Replace 5V regulator

Post by **jhsa** » Sun Mar 23, 2014 6:39 pm

Bob, did the atmega chip in the 9x really survive that 12V blast or did you replace it?

bob195558 · Post by **bob195558** » Sun Mar 23, 2014 8:13 pm

Hi João,

I do not know. I do not see any damage to it and it look's really good.
I did what I could troubleshooting and the values are not the same, as a good working 9x mainboard.
I replaced some caps and installed the 5V Regulator and the ohms values were still not correct.
I do not know how to troubleshooting for it.
I would like to know if the CPU is OK too.

If you have any suggestions to check it out, I would like to try them.

I hope to remove the stock CPU chip from the Fuse Brick mainboard today and maybe solder the new ATMEGA2561-16AU CPU Chip in its place.

When I have this completed, I think the next thing is to try flashing the er9x firmware to it.
Is there anything special I need to do and/or know when I get to where I am ready to power the new ATMEGA2561-16AU CPU Chip up ?

Bob

When you come to flash the '2561, the factory default is to use its internal oscillator, divided by 8, so it is slow. You need to set the fuses correctly (values in another thread). To do this, you will need to slow the programmer clock down (Avrdude -B or -b, can't remember which).
Once the fuses are set, the CPU will use the external crystal so will then run at full speed.

Mike.

Removed Fuse Brick ATMEG64A AU 1139 CPU from Stock 9x Mainboard, using CHIP QUIK.

(Upgrading to the ATMEGA2561-16AU CPU Chip) 2561

Hi,
I have removed the Fuse Brick ATMEG64A AU 1139 CPU from Stock 9x Mainboard.
Please View the Photo's and if you see something that looks like there may be a problem, let me know so it can be correct it.

: Removed Fuse Brick ATMEG64A AU 1139 CPU

: Removed Fuse Brick 9x ATMEG64A AU 1139 CPU CHIP

Next I soldered the ATMEGA2561-16AU CPU Chip on to the Stock 9x Mainboard.

: New ATMEGA2561-16AU CPU Chip

Soldered ATMEGA2561-16AU CPU Before cleaning it up.

After cleaning!

I will inspect the connectors with the 20X Magnifier Eye Loupe Lens Jeweler Watch Repair LED Light.
And if the Photo's look good to you, ..... I will install it into the 9x Radio.
I will need help with setting the fuses correctly as I do not have a good understanding about the fuses and setting them.

Also see here for a place to purchase the ATMEGA2561-16AU Chip: (http://openrcforums.com/forum/viewtopic ... =60#p71554).

To Flash your new ATMEGA2561-16AU chip use eepe, see here: (http://openrcforums.com/forum/viewtopic ... 105#p74295).

Inspect the surroundings with the magnifier. When I replaced the chip on one of my tx's, I had a very small blob of chip quik shorting a smd capacitor. Lucky I checked all with the multimeter and magnifier.

Edit March 19, 2019, Note: Go down to where I used eepe to setup the 2561 chip:
(viewtopic.php?f=95&t=3819&start=120#p74295).

Hi,
I have the new ATMEGA2561-16AU2561 Chip soldered to the 9x Mainboard and the ohm readings have check OK.
I have installed the upgraded 9x Mainboard into the FlySky 9x Radio.
I have the SmartiesParts Programmer Board installed for the USBasp connection to the computer
and it is ready to be powered up to set the Fuse Settings and flash the er9x-2561 firmware.

I have not done this before and I am not sure how to do these next steps.
I would like to use the same process that you used when you did your Fuse Settings and Flashing er9x -2561 firmware to the 2561 Chip.

And do I need to make ...... the programmer, Slow Down by adding -b and/or -b100 to the Extra Arguments on the Burn Menu (in Companion9x and/or myAVR ProgTool and/or other ?)?

I am not sure which Software to use and how to use it at this point.
eepe or Companion9x or AVRdude-gui v0.2.0 or Bill suggested using: myAVR ProgTool V1.39:

Bill wrote:Bob,
Forget the dudes Dude a simple tool that will do everything you need is myAVR progtool:
http://shop.myavr.com/index.php?sp=down ... wort=dl112
All you need is to do then is to load the correct hex file.
It includes simple diagnostics and fuse setting.
If the processor is bricked however you will need to apply an external clock to the processor to get it to talk to the programmer.

Are these the correct setting for Companion9x:

Bob

Post by **jhsa** » Thu Mar 27, 2014 8:11 am

Does myAVR ProgTool support UsbAsp? Didn't know that. The option in extra arguments is -b100 and not -b.
Don't use companion to set the fuses on the 2561 as it doesn't support it as far as I know. 2560 IS NOT the same chip.

Question for Mike.
Eepe supports the 2561, but can it program the fuses like we do with the other chips? If not I think it would make it easier if it did.

Bob, you might have to find a program that supports both usbasp and the atmega2561. Try searching for "extreme burner" or "Xtreme burner" I'm not sure. That might do the job. I never used it yet I gotta say.

Good luck

eepe from r393 does include fuses setting for the '2561. It ignores the EEPROM protect option and always sets the fuses so the EEPROM is protected from being erased when flashing.

Mike.

Edit: I've just changed the code to handle to protect option. That will be in the next revision of eepe.

Post by **jhsa** » Thu Mar 27, 2014 9:37 am

Bob, then I think you should try eepe r393. Don't forget -b100 in the extra arguments when setting the fuses. after setting the fuses this option is not needed anymore and you can remove it from the extra arguments.

João

bob195558 · Post by **bob195558** » Thu Mar 27, 2014 3:13 pm

Hi Mike and João,

I am good to try eepe!

: Updated eepe to Revision: r397

I have updated eepe to Revision: r397 (is this version OK ?)
and I have entered the following Data and Selection Options to:
Preferences / Version to download: er9x-2561, Processor: m2561.

Note: The "Processor" setting in the photo needs to be changed to m2561 in this photo.
(Processor setting to: m2561).

: "Preferences"
Note: The "Processor" setting needs to be changed to M2561 in this photo. (Processor setting to: M2561).

AVRDUDE Configuration / AVRDUDE Location: C:/Program Files (x86)/eePe and eepskye/eePe/avrdude.exe,

Programmer: usbasp, mcu: m2561, Port: _ _ _, Extra Arguments: - B 1000.
Note: Needs to change the "Extra Arguments" settings in the photo to: -B 1000

: "AVRDUDE Configuration"
Note: Needs to change the "Extra Arguments" settings to: -B 1000

Is the next thing to do (when I an ready to give it a try) connect the 9x Radio
with the new ATMEGA2561-16AU CPU Chip through the USB to eepe ?

: Which one: Set Fuses to Protect EEPROM
or Reset Fuses to Factory Default.

Next I think, is to do, the Fuse Settings.
I am not sure what to do at this point.
Do I click the Set Fuses to Protect EEPROM or Reset Fuses to Factory Default?

: Set Fuses

Do I need to set any of the Fuse Settings for '2561 when using the updated eepe:
Low: 0xDE
High: 0xD1
Ext: 0xFC
and if it needs to be set, how do I make these settings?

: Set Fuses Screen,
NO 9x Radio connected yet!

Depending on which to select with the 9x Radio connected through the USB SmartieParts programmer Board,
I then Click on the correct Set Fuses option.

NO 9x Radio connected yet!

Then after this I should be able to Flash er9x-2561 firmware to the new ATMEGA2561-16AU CPU Chip / FlySky 9x Radio.

Add Edits:
Note you need to corrected some of my settings that I have in the photos, they are incorrect.

Read further down this string for all the proper settings with using eepe to flash the new chip.

Bob B.

Post by **MikeB** » Thu Mar 27, 2014 3:27 pm

Looks correct. It will set the fuses to protect the EEPROM, the option is ignored in eepe at present (it will be handled in a future revision). You do not have to set the fuse values.

Mike.

Post by **jhsa** » Thu Mar 27, 2014 3:38 pm

In preferences your photo shows the m64 processor as selected? better change it to m2561

Mike, would it help to add an option to read the fuses so we would be able to test the connection before writing something? At this point you can't do any firmware reading. but we would be able to read the fuses.. Also in some cases the fuses changed for some reason and the radio stopped working properly. In some cases it became very slow if I remember. wouldn't being able to read the fuses help to diagnose the problem?

Thanks

João

bob195558 · Post by **bob195558** » Thu Mar 27, 2014 4:31 pm

Hi João,

Good catch!
I placed a Note under that Photo saying it is now corrected.
It was an older photo which I took before I saw that it needed to be changed.

I think, when I Set Fuses I need to use: Set Fuses to Protect EEPROM.

I need to go out now, so I will try it when I get back.

Bob.

Hi Mike and João,

It did not work.

1) When I turn on the FlySky 9x Radio the display screen is blank with the Back Light on.

: Powered New ATMEGA2561-16AU CPU Chip up.

2) I rechecked all the Data and Selected Options and they are good.
To set Fuses on new ATMEGA2561-16AU CPU Chip:
Update eepe to Revision: r393 and up. Entered Data and Select Options:

3) I then clicked: Set Fuses to protect EEPROM.
4) Then I clicked OK.
5) And there is an error, when it ran:

6) Trying to flash er9x-2561 failed also.

I think the programmer can't see the chip.
1- Check the connections. You have the SP Board right? Make sure that all the pins make contact.
2- How are you powering the radio? using the SP Board? Latest versions of the SP Board require the tx to be ON as far as I remember.
Ahh, NEVER, NEVER use the -F option. That can brick your radio.

João

mmilan · Post by **mmilan** » Fri Mar 28, 2014 9:20 am

Bob,
You might have try using the command prompt in Windows. I used this command with success:
C:\Program Files\eePe>avrdude.exe -P USB -c usbasp -p m2561 -B 500 -u -U lfuse:w:0xDE:m -U hfuse:w:0xD1:m -U efuse:w:0xFC:m -v

Your path may be different.

Post by **MikeB** » Fri Mar 28, 2014 9:33 am

I just checked Avrdude, you need -B 100 not -b 100, or even, for setting the fuses -B 1000. It doesn't matter if you slow the clock a lot, there are only a few bytes to transfer.

Mike.

Post by **jhsa** » Fri Mar 28, 2014 9:42 am

I'm always confused with -B and -b

João

KAL · Post by **KAL** » Fri Mar 28, 2014 11:57 am

'cause I'm not very familiar with avrdude and its parameters I'm using AVRDUDESS,
a very nice GUI for avrdude so far.

Checking and setting fuses is very easy, you can save own presets ...

The SP Board is the Rev. 2.3 and I do hear the USB sound connecting it to my Win 7-64bit computer.
Yes, I believe with the Rev. 2.3 SP Board the 9x Radio needs to be turn on to make connection to the 9x mainboard.
Thank you, João for the Warning about the -F option, Do not want to go there.

I have change Extra Arguments setting to: -B 1000 for setting the Fuses.

Hi,
Before I do the next step to try to Set the Fuses for new ATMEGA2561-16AU CPU Chip.
I did a quick test for the address of the AVRDUDE Location.
I changed the Data and Selection Options back to my FlySky 9x Radio with er9x-frsky firmware and I was able to: Read Memory from TX.
My thinking is the AVRDUDE Location address is working OK.

Bob

bob195558 · Post by **bob195558** » Fri Mar 28, 2014 4:45 pm

I think its working! It looks like the Fuses are set!
Its writing er9x-2561 to it now, it is taking a long time to write to it.

OK, just wait for it to finish, then remove the -B 1000 from the extra arguments, that's what is slowing it down. You need to -B 1000 to get the fuses written, but then the '2561 will be clocked at full speed.

Bob: You need to read this thread: viewtopic.php?f=95&t=3594. Some of it you can skim over, but you will need to do one of the mods suggested to make sure you don't get a reboot when using a horizontal trim switch.

Hi Mike and João,

I have done this mod: Digital Ground Fix for Horizontal Trim Rebooting and I did Bill's version for this mod fix.
See: (http://openrcforums.com/wiki/index.php/ ... Ground_Fix)
"Also See Bill's version of Horizontal Trims Rebooting / Digital Ground Fix @: (http://openrcforums.com/forum/viewtopic ... 120#p69475)"

I will review the: "9x upgrade to ATmega128A3-AU + Reboot With Horizon Trims" String Posting soon.

The Flashing is complete, But some things are not working correctly.
Note: I have removed the -B 1000 setting from the Extra Arguments option.

Added Note Sept 7, 2018: Installing the new 2561 chip and flashing it went very well

,
but I did have another problem with several of the (Hobby King) button switches in being very corroded,
so I had to replace them as you will read further on.

This is the 9x Radio that got the 11.6 volts to it, because of a Wrong 5v Regulator (was 12v) I installed by error.
Before the mishap with the wrong regulator, everything was working in this 9x Radio.

in this 9x Radio the parts that have been replaced are:
1) 9x Mainboard that had a Fuse Bricked CPU now upgraded to the '2561 CPU.
2) Are using a different SmartiesParts Rev. 2.3 programmer board.
3) There is a different Stock 9x transmitter module plugged in to it also.

Note: I have received a new 9x TelemetrEZ board to replace the burnt one.
It has not been installed yet, ..... so No 9x TelemetrEZ board is installed in this 9x Radio yet.

With great difficultly, ..... I was able to calibrate the pots after flashing was complete.

Here is what is not working: 3 of the buttons are not working properly. (as I have been able to see so far)

1) The MENU button is not working.

2) The Exit button is not working.

3) The Minus button is not working.

Its difficultly and/or impossible to move around in the menus without working buttons.

: er9x-2561 Radio

Could, not having the 9x TelemetrEZ board installed yet, affect the buttons from not to work ? (answer: NO).

Bob

bob195558 · Post by **bob195558** » Fri Mar 28, 2014 8:16 pm

Hi,
Maybe when I installed the 9x 2561 mainboard, I did not get the buttons installed correctly.
I think I need to check this out, But they do feel like they are working correctly.
Still ..... it may be the problem.

Buttons Up, Down and + work good.
