Firmware CRC mismatch detected

[Simon1]

Hi,

I've been trying to reinstall the firmware after something got corrupted. I've used axoloti-win-1.0.12-2-java1.8.0-191.msi. I'm using Windows 10.

When I've tried to connect to the board I get an error message saying Firmware CRC mismatch detected!. I've selected to update the firmware but the green light on the board doesn't blink (error message says the leds will blank for a minute).

Not sure where I'm going wrong. Any help would be appreciated.

Thanks in advance,
Simon

Firmware CRC mismatch detected

Hey @Simon1

According to this thread, a flash rescue maybe could work?:

CRC mismatch > update firmware > connects > but not working

Is that the board where you damaged the tracks between the processor and the sdram chip? In that case only a rescue flash (dfu) will work and all objects that use sdram will result in unpredictable behavior too. #define BOARD_AXOLOTI_V05 1 is correct for board revision 1.0 too. When a CRC mismatch is detected, patches will not run, preventing more weirdness.

Herre is how to do the flash rescue. Push the link and you will be taken to the instructions:

No available USB device found with matching PID/VID

The symptoms you're reporting could be caused by a power-only USB cable, but you have already verified, great! The next thing to exclude is anything related to firmware. Could you try a "rescue flash": remove power from Axoloti Core, and then connect the micro-USB port to your computer while holding button S1. The LEDs will stay off when in DFU mode. Then select in the Board menu -> Firmware -> Flash (Rescue)... If the LEDs stay off, but you still get "No devices in DFU mode detected.", then …

Fantastic. That seems to have sorted it.

Thanks.
