Re: TH9X/Turnigy 9x bricked after flashing

Finally I solved this issue. Well, what I did: I put a external oscilator to generate a 1Mhz clock on the 24 pin of the Radio microcontroller (normally is an "ATMEGA", but in my case, a "Green ed040502-h16d", a clone of the common ATMEGA). Any circuit capable of generating this c...

João
About the resistors, only one goes to the programmer output pins, R4 to TXD, but this pin is not in use. :|

Re: TH9X/Turnigy 9x bricked after flashing

Also on your programmer, what are the values of R1, R2, R3 and R4? João Yesterday I bought an Arduino Uno Board, Do you think that it could help in something? I read that people are using an oscilator signal to reset the fuses, applying 1MHZ at pin 24 of the ATMEGA. Could use arduino to generate th...

Re: TH9X/Turnigy 9x bricked after flashing

Please confirm that all the connections between radio and programmer are good. Is the programmer permanently installed in the radio? is your programmer powering the radio's processor when programming, or are you turning the radio ON? A good picture of your radio mainboard and connections could help...

Re: TH9X/Turnigy 9x bricked after flashing

some USBASP do need to be rebooted to be able to connect again, that is known. I know that this probably do not work, but what about if you try to read the eeprom instead of flashing the firmware?? You can also try to READ the fuses using companion.. you said you also mod the radio for telemetry? w...

Re: TH9X/Turnigy 9x bricked after flashing

welcome to the forum.. I aways used a usbasp v2.0, and -F parameter , but yesterday I got this issue. I believe that this was what possibly bricked your radio. You should NEVER EVER use the -F parameter.. Where did you read that you should use it?? :o :shock: We always advise people not to do it.. ...
