Flashing M128

Then there should be thought about the possibility of an automatic transfer in eepe.
(not quite easy to cover all combinations I guess ...)

And if it is not possible? Should that stop the development because we are too lazy to re-program the voice, audio and haptic again?

There are a few more options in the voice alarms menu that we didn't have before.. Not sure if it would be possible to make a conversion, even because eepe would have to recognize which logical switches are being used for voice and which not.. Hmm, maybe that could actually be done.. but we would have to check everything anyway.. so, better to just program them all.. it shouldn't take too long if you know what you have to do..
And I think Mike already has a lot to do... on his own..

we can make a little effort too.. After all we get all this for free

No, no!

Please not stopping this great evolution!

I haven't thought about you and me ...

(I have still transfered the voices in all my 28

model setups )

Thought of all the others (e.g.

Joe Average) ...

Klaus

Post by **jhsa** » Sun Dec 21, 2014 2:51 pm

Yes. True.. Joe Average is very lucky that Mike never really did eeprom upgrades because of that same reason I believe. That could probably mean reprogramming the complete model if not possible to convert with eepe

Mike, please correct me if I'm wrong here.
Compared to that, programming the audio again in a much better implementation is kids play. Also I think that Joe Average that is the one that most owns radios with the m64 chip will be pleased with the extra flash savings

João Average..

I'm proposing a way forward for voice alarms etc. on the M64 on the er9x development thread (viewtopic.php?f=5&t=2&start=1980#p91023). Please continue this discussion there.

Well I pick up where I left off,Quasimotoglez with "FlySky FS-TH9X with erx firmware LOCKDOWN!!!!" I finally got the board from HK and installed in the radio (it says Turnigy and no trim issue on power up)

I painted the radio with GUN GRAY, installed the new board and back light, it comes with the Atmel Atmega 128A

I’m afraid to mess thing up and bother you guys later with a disaster that I may make later on (jhsa and mike thanks so much for your comments and effort in my past problem)

"The more I read about it the more confusing I get"(me)

I downloaded the zip file er9x-128B, but witch one should I put?

So I'm expected to have an issue or NOT with the horizontal trim or some other software/hardware issues after software upgrade so I did the trim mod before I install the er9x software

Please, if it is possible and no time consuming from mike or somebody, can you guide me to all the process and steps (including links, pics and videos for at least successfully UPDATING this radio.)

Best regard to mike and jhsa thank you for your time.

Tony

Please don't keep posting the same content on different threads. We will see it if you post it once

Actually I already replied to it on the first thread you posted it.. I f you wish you can create another thread for your mods, and keep all together.

Hi Quasimotoglez,
What are you using for the transmitter module?

You may want to upgrade to the new 9Xtreme Upgrade Board for 9x Radios when it becomes available.
See: (viewtopic.php?f=95&t=7182&p=99410#p99410).

You don't have to apologise.

It's just that you might get better help if you keep it all in one place..

reviving this thread.
I've been out of the loop for a while.
I've got a couple of modded 9x's with M128 chips.
I like the idea of loading a bootloader & flashing over USB via an FTDI adapter.

I've got a few questions...
- where can I find more info on loading the latest version of the bootloader? Can I load openTX on the 9x with the same bootloader setup?

- Confused on which pins on the AVR need to be connected to the FTDI adapter. Normally, It's the TX & RX pins from UART0 on an AVR/Arduino, plus the DTR pin (via a cap&pull-up resistor 'bounce' circuit). However, I'm seeing mention of the SPI pins though. How's this supposed to work?

Any chance that USB joystick functionality can be implemented on the 9x by using the bootloader+TTL/USB adapter setup?

Post by **MikeB** » Wed Sep 21, 2016 9:02 am

The bootloader for the '128 is included in the .hex file of er9x-128, you just need to flash the latest revision (or test version).

You use the same pins as used for the telemetry serial, I thought this post: viewtopic.php?f=5&t=6525#p90924 describes how to connect. The confusion of the SPI pins is due to the 'normal' method of flashing (USBASP) uses these same pins but as a SPI connection.
You only need Tx and Rx. You access the bootloader by holding the two horizontal trims inwards at power on. This is detected in er9x, and passes control to the bootloader.
I don't think openTx have included this, so if you have er9x flashed, you could flash openTx once, but then you will lose the ability to get to the bootloader.

USB joystick will require a lot of work to write a USB HID driver on the '128, unless there is the source code of one available.

Maybe not for the Atmega128, but for the atmega8, 88, 328,168, etc

The same that USBASP uses. I think you already know it

So, could this be a real possibility, or is it just too complicated & resource-heavy to implement on the '128?

MikeB wrote:The confusion of the SPI pins is due to the 'normal' method of flashing (USBASP) uses these same pins but as a SPI connection.

ok, got it.
Seems a bit strange that the SPI pins are being used as a standard serial port. Is this some kind of software serial implementation?

MikeB wrote: I don't think openTx have included this, so if you have er9x flashed, you could flash openTx once, but then you will lose the ability to get to the bootloader.

Ok, I understand.
Does openTX even support the 128?
Are you one of the openTX devs? If so, could the 128 bootloader be something that you could push for?

(please excuse my ignorance, I've only ever looked into openTX for my taranis, not for 9x's, didn't even realize it was possible to load openTX on a 9x)

Post by **MikeB** » Sat Sep 24, 2016 11:11 am

I'm not at all sure if the processor could drive a software USB port and still be able to handle everything else.

"Seems a bit strange that the SPI pins are being used as a standard serial port."
No, it is the serial port pins being used for the programming SPI port that is strange. There is a SPI port on other pins.

OpenTx does support the '128 on the 9X.

Dear Mike,

Today I have changed M64 to M128 a load the firmware "er9x-128.hex", when power on Thr and Ail switch warning.

I reloaded the firmware "er9x-frsky.hex", It work well but Eeprom size same as M64.

Can you please send me firmware for M128 with Frsky mod.

Best Regard,
Luu

Post by **jhsa** » Wed Oct 12, 2016 8:23 am

Load the "er9x-128.hex" again.. Then hold the left horizontal trim to the left for about a second while turning the radio ON. This will enable the hardware menu that is disabled for safety.
Now go to Radio Setup / Hardware, find the option "Frsky Mod Done" and set it to ON. Now your switches should work.

João

Dear Mike,

I have a problem with the firmware "er9x-128.hex".
Telemetry (Screen 3) - Custom display: Up to 6 Telemetry sources can be displayed but only 5 items can be selected, the last one can not be selected.

Can you please help me to check this.

Thank you so much.
Luu

Post by **MikeB** » Tue Nov 15, 2016 9:55 am

Have you flashed revision 820 from http://www.er9x.com?

I recall this as a bug and it is fixed in test versions available from here: viewtopic.php?f=5&t=4598#p64969. Try this one: er9xProv821g_multiDSM-2.zip.

Mike.

Hoangluu · Post by **Hoangluu** » Wed Nov 16, 2016 12:56 am

Dear Mike,

Thank you for your reply.
Yes, I flashed revision 820 from http://www.er9x.com.
I will flash file "er9x-128.hex" in "er9xProv821g_multiDSM-2.zip" and let you know the result tomorow.

Many thanks,
Luu

Dear Mike,

I have flashed file "er9x-128.hex" in "er9xProv821g_multiDSM-2.zip" again, telemetry (Screen 3) - Custom display: 6 items can be selected now.

I built an Openxsensor with GPS and IMU as this thread https://www.rcgroups.com/forums/showthr ... ?t=2597766 and DIY FrSky RX module(2 way) as this thread https://www.rcgroups.com/forums/showthr ... ?t=2124647.

Both of them worked, but the GPS result display on Tx are not exactly (GPS altitude, GPS speed).
GPS altitude is difference too much from Barometric Altitude.
GPS speed is too low (not sure the unit) when compare with my car speed (Put openxsensor on my car when tested)

If you have time, please have a look on this problem.

Thank you,
Luu

Post by **MikeB** » Thu Nov 17, 2016 10:20 am

GPS altitude is absolute, above sea level.
Barometric altitude depends on the local air pressure, and is auto zeroed to be ablove ground level.
These two will therefore normally be different values.

The GPS speed form the FrSky sensor is in knots, so this is what I expect from the openXsensor.

Mike.

Now I understood,
Thank you Mike.

Hoangluu · Post by **Hoangluu** » Mon Nov 21, 2016 1:02 am

Dear Mike,

I have tried to set GPS speed in Km/h by use a scaler in ER9x but unit in scaler setting menu don't have Km/h.
GPS altitude in Telemetry screen is *10 of GPS altitude in Custom display screen.

If you have time, please have a look on these problems.

Thank you,
Luu

Post by **MikeB** » Mon Nov 21, 2016 9:45 am

Which GPS altitude value is correct (so I know which to change)?

Mike.

Hoangluu · Post by **Hoangluu** » Mon Nov 21, 2016 9:59 am

Dear Mike,

As you say, GPS altitude is absolute, above sea level. I am not sure which value is correct but when I tested at my home GPS altitude in Telemetry screen is 12, GPS altitude in Custom display screen is 1.2.

Thank you,
Luu

Dear Mike,

I have take 2 picture for yor more imformation.

I'm just doing a formal release of er9x/ersky9x/eepe/eepskye. When I've got this out, I'll be able to look into these.

Mike.

Hrllo,
I just tested the serial and it works really nice for reading/writing eeprom and reading radio firmware. I want to flash the testversion with more multiprotocols from 15. january I think but I think the version there is with the bootloader, right? Do I have to flash the radio with ISP again or is there somewhere a firmware without the bootloader?
Thanks for answers
