Hi everyone,

I think I might have overwritten the bootloader. I can't connect to the OpenIMU300ZA anymore.
Could anyone please share bootloader.bin and recovery image file for OpenIMU300ZA EVK SN1908400116

Hi everyone,

I've got OpenIMU300ZA EVK board. SN:1908400166. I connected to the device from python program and was able to fetch and record the data.

Device: OpenIMU300ZA5020-3885-01 1.0.22 SN:1908400166

Today I tried integrate GPS in the device by uploading the INS firmware. initially it worked and started showing GPS locations but soon it crashed automatically & went into bootloader mode.

Device: OpenIMU_Bootloader_4.0.3. Unit SN:1908400166

But when I tried uploading new bin file using STlink debugger, the program got uploaded but it is not connecting now. What to do? latest messages are here

I think I lost the firmware and bootloader both. I don't even have the backup image file with me. Please help me to fix this problem.

Hi everyone,
I've got OPENIMU300ZA EVK. But the values I'm getting for acceleration doesn't seem to be correct. z direction vector should show -9.8 approximately. but it is showing 10.10 How to correct it or calibrate it?
