Hi Guys,

I need to get the original firmware as supplied with our sensors as the backup wasn't completed properly and after download disrupts from website, we have had to use different firmware downloaded from the forum.

We have the units communicating with the firmware (1908811027__1.0.2_a2-k5jfscxs.bin) and with just this firmwere the canbus will work but we need the later firmware uploaded so as we can change the CAN msges.

If we upgrade the units firmware from the developer website,(VG-AHRS) it will download and work on the developers website but as soon as we connect to canbus it faults the canbus system. Then if we reload that bin file we found (1908811027__1.0.2_a2-k5jfscxs.bin) and not change anything the canbus works fine but we cant change the code. Does anyone have an original firmware bin image close to these serial numbers while we are waiting for original bin files.

The 2 units are are
OpenIMU300RI-EVK Part # 8350-3311-01, Serial Number - 1903139137
OpenIMU300RI-EVK Part # 8350-3311-01, Serial Number - 1903139126

I have bought 2 x OpenIMU300RI Units, programmed one successfully using vg_ahrs and aceinna developer site. once programmed tried to upgrade to a different firmware (VG_AHRS_1.0.3_a2) via aceinna site. update failed and timed out. This hass now happened with both of the units and canot connect via, RS232 or Can. I tried to start with bootloader and just cycles baudrate with no comms. I can successfully connect with ST-Link and Visual Studio Code and download firmware but cant connect to aceinna python server or computer. Have also tried to flash original firmware and still nothing. Can you please provide some support for this. Only have one device serial numbers as second wont connect at all after flashing using ST-Link.
