We have three OpenIMU300ZI units.
One of them is working correctly with a custom firmware. Is a modified version of the original VG_AHRS source code with baudrate changed to 230400bps, and 200Hz sampling.
The other two units have gone out of service after the firmware update attempt. I don't have the backup binaries to program them with ST-LINK Utility, because I only read and save a bin file of 129kbytes (not all 512kbytes). I think that the firmware is corrupted.
I have tried other recovery tips that are explained in this forum, but any success.
The serial numbers of those two OpenIMU300ZI are:
Could you send us the binaries of those units to program and recover them.
Thank you and regards,
