Support writing calibration data #6

Open froqstar opened 3 weeks ago

Hi, newer IJV firmwares require (?) writing a custom calibration to the radio, but I could not figure out how to do that with K5TOOL. Is it supported, and if yes how to do it?

Thanks!

just write it to a proper address, k5tool allows to select custom address for writing. Calibration data is started from 0x1e00 offset, so you can write it with the following command:

./k5tool -wree 0x1e00 custom_calibration.bin

Before doing it make sure you have backup file taken with ./k5tool -rdee, it will save backup file to eeprom-0000-2000.raw. You can use this file in future for recovery.
