Speeduino CORE4 board, 202207 firmware with some minor mods (no changes in data structures or new functions whatsoever).

I followed the instructions found here (https://wiki.speeduino.com/en/Installing_Firmware) to mod the firmware, installing the Arduino IDE and Time library; the code compiles correctly with no errors.

I randomly get a CRC Check failure dialog box when burning data to the ECU in Tunerstudio, and the dump always look like this when it happens:

Any ideas on why this could happen? It did happen before, with the standard firmware, but it was much less frequent.

The 202207 series code seems to Be troublesome. I had to Back to 202108. Resets, forced ofline. Random studer/10afr stuf. Now when i got Back to 08 series noin of that just Works.
