About the font corruption, it's normal. Official firmware use fonts that are located in the flash, unlike OpenGD77 which embed the fonts inside the firmware itself.EB3EEL wrote: ↑Mon Mar 23, 2020 1:31 pmWEEELLL. finaly the radio works, an stupid mistake in the connections, finally can connect to mcu, reprogram it and its alive now, but some little problems, one is that if i upload an official firmware the radio dont work well, the display is in black blocks and dont do anything, after some tests i find that if install the opengd77 firmware all works, the other problem is that i lost the calibration data and cant write it with flash manager, the program dont find the radio, seems that i have to calibrate the radio manually.
Thankyou so much for your help, now i have to finish the program and enjoy it for a long time.
Salut

Since you erased the MCU, you lost everything. But it's recoverable by flashing everything back, using the extra window from the CPS.
Of course, your calibrations might be slightly off since you need to flash the ones from another transceiver.
I can share MCU/etc dump, via private emails.
Cheers.
