PCAN USB FD firmware update fails
Posted: Thu 11. Jun 2026, 12:59
When using Peak Flash 3 to update the firmware on my PCAN USB FD, it always reports:
"Error: Accessing the momory of the device failed"
When the PCAN USB FD enters bootloader mode (flashing red light?), the USB drive appears on my laptop and I can write to it.
Once Peak Flash 3 fails, the PCAN USB FD remains in bootloader mode until unplugging/re-plugging.
Where can I download the 3.5.1 firmware to manually update the device? (plus some instructions to ensure it is correclty updated).
