Re: Bad Eeprom error. 9xtreme/encoder.

Thanks Mike, I installed the app and it works.

Re: Bad Eeprom error. 9xtreme/encoder.

Suggest, maybe it could be a hardware problem. If you have a bad switch or a bad chip it could be causing the troubles. Many years ago I had a new 9x that bricked when programing it and later found the selecting switches were corroded. After replacing several of the selecting switches, it worked OK...

Re: Bad Eeprom error. 9xtreme/encoder.

Oh, I see.. :) But if the radio is completely dead, I don't know if maintenance mode will work. As far as I know it is part of the firmware :) But Mike knows better than me of course.. :) João Yep, that is the thing, bootloader and maintenance mode worked fine.

Re: Bad Eeprom error. 9xtreme/encoder.

I have just checked on my 9xtreme radio. You do have a "Restore" option in the Radio "Settings / EEPROM" menu. You can use it to restore the EEprom you have saved to the SD Card. João Yes, but that is when the radio is working, not like the other days with the radio completelly dead, lol. Hence Id ...

Re: Bad Eeprom error. 9xtreme/encoder.

I think you can :) but not sure. I know we can backup the complete eeprom to the SD Card. I don't have the radio with me at the moment, but you can check in the Radio Settings/EEprom. You might have to unlock the menu by holding the left horizontal trim to the left at power ON. :) João Hi Joao, yes...

Re: Bad Eeprom error. 9xtreme/encoder.

Thanks Mike, I will test it tomorrow morning, first thing I will do.

This time I did not get the bad eeprom message but just got that full black screen. Not sure if you can see anything in the files I posted.

Thanks again, will post tomorrow :D

Re: Bad Eeprom error. 9xtreme/encoder.

I have been thinking about this and I have some ideas: Blocking access to the encoder removed most of the issues... Maybe you could block it until the splash screen is gone. Also another thing that would help a lot is to be able to restore the eeprom from the bootloader or from the maintenance mode....

Re: 9x Exit button size.

Thanks for the help, guys, very appreciated.

In this case the SMD button is broken. He opened the radio and checked inside and it does not do any click... So it needs replacing.

Re: 9x Exit button size.

Just to point the button was damaged in shipping. It does not make the characteristic "click" when pressed anymore, and he has to press it very hard to make it work, so it looks like it needs to be replaced. Unfortunately I dont have more 9x radios so far except my extreme so I cannot measure or che...

9x Exit button size.

Hi friends. A friend of mine has the exit button damaged. It needs to be replaced. Could you tell me the size? I guess it is a SMD switch, 4.5mm? How long?
Thanks!

Re: Voltage drop in 9x

Easy to add the extra build, so I've posted a '128 version for the Green processor created by doing a full build of all versions, so it will be updated and released with all the other versions.

Re: Voltage drop in 9x

I'll think on what to do permanently. Maybe I need to build a '128 version specifically for the Green processor. I think that will be the easiest solution since I don't like the idea of adding the 300mS software watchdog to the standard '128 version as that would increase the watchdog timeout to 0....

Re: Voltage drop in 9x

I'm wondering if the Green chip is clocking the watchdog faster, and using some unused bits in the configuration register to set up the longer timeouts. Either that, or the watchdog is just not working properly. I've just posted a new test version that includes a 300mS software driven watchdog, whi...

I've just posted a special test version, for the '128, with the watchdog set to 2 seconds instead of the normal 0.5 seconds.
