Turnigy 9X AFHDS 2A system

Post by stotty1111 » Sat Apr 13, 2019 4:29 pm

Hi its me again,

Member of an adjacent model club turned up at my club today with the above radio system. It will not boot, just beeping and displaying
Eprom error message.
I just want to ask, do I re flash the eprom with the Eprom from a similar radio followed by a trial, then reflash the firmware from the other radio?
If not what should I be doing?
I would try the ER9X route suggested last year, but, the guy wants to try to retain the AFHDS 2 A system as he hasn't got an original transmit module for the said ER9X route!

Also been scratching around trying to find info on an ORX TX module 18 DBM Walkera Switchable unit, Can this module be used in a Turnigy 9X, unflashed or flashed, might be able to use with the above TX perhaps?

BUMP!!!

Ok, so should I give it a go and reflash a copy of the eeprom file from a similar Tx? Will it compromise the tx if it doesn't work?If it didn't, I would then try flashing ER9X and use an Orange module, as 6 channel rx's are currently around £3.50 on H/king!

AFAIK the module just takes PPM and handles the AFHDS2A on its own (single model), the software of the radio is unmodified. Either flash the EEPROM from the stock firmware which should get things working again, or move to open software.

Read the eeprom and firmware from a similar 9x AFHDS 2a using a smartie parts basic board, then flashed the eeprom followed by the firmware.
The firmware appeared to be accepted following the screen displaying progress! When rebooted just a beeeeeeeeeeeeep and error message.
where would I find the stock firmware?

By default flashing firmware erases the EEPROM. You must flash firmware first and EEPROM second.

If you are flashing using eepe, the is an option, under the burn menu, to "set the fuses to protect the EEPROM". If you use that, then flashing the firmware will not erase the EEPROM.

Ok, flashed stock firmware and then eeprom from stock package. Some progress, now getting switch error message and intermittent beep.
Fuses set to protect eeprom!

I assume you have tried setting all the switches in different positions to try to clear the switch error. I've not used the stock firmware.
I also assume the radio hasn't had the telemetry mod done to it.

Ok another day another problem, just bought a blank screened 9X off Leboncoin, didn't pay a lot for it.
Switching on, no display, installed a S/P basic board, reset fuses to protect eeprom, it took that instruction apparently, tried to flash stock AFHDS 2A firmware, it ran thro' the motions, but after reading it came back with:-

AVRDUDE.EXE did not finish correctly and at the bottom of the steps

AVRDUDE.EXE: verifying....
" : verification error; first mismatch @ byte 0x0004
0x0c ! = 0x8c
AVRDUDE.EXE: verification error; content mismatch
AVRDUDE done - exit code 1

Help!!!

It sounds like the processor may be "broken".
Read the flash memory to a file, zip the file up and post it here (or PM it to me). I'll have a look at it, it may well tell me if the processor is bad.

If processor turns out to be bad, then one option could be
to upgrade to the ATMEGA2561-16AU Chip: viewtopic.php?f=95&t=3819&start=120#p74105
Er9x on 9x radio, with Smartieparts Programmer and TelemetrEZ Board.

Ok, can't read flash memory, its telling me to try a later version, think the version I have is the latest. I have an old m/board from an earlier version, i'll piggy back it with all the plugs transferred and give that a go!
