PCAN USB FD firmware update fails

Post by annoyed » 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).

Hi,

please send us an email with your devices serial number (printed on the PEAK sticker) and refer to this forum entry.
