Hi, I tried to update the firmware of my arch pro board, but now it is not recognized by my computer(I run Linux). I tried to press the reset button while connecting it to the usb port, but it doesn’t work.
Thank you for your help.

Maybe you need to check the USB cable, see if it’s broken, and see if the USB port on your computer is working properly.

I tried with another cable, it doesn’t work. The usb port are working properly. What’s weird is that it was working perfectly before the upgrade, but after I unplugged the board and plugged it back, it was not recognized anymore.

Update or Restore Firmware

The latest firmware version for the Arch Pro is v0221 built on Jan 28 2015. To check your firmware version and build date, open the MBED.HTM or DETAILS.TXT of your MBED disk in a text editor.

To update:

  • A Windows or Linux computer is needed.
  • Download the latest firmware.
  • Press and hold the Arch Pro’s BUTTON and power it ON.
  • A disk named MBED LOADER will appear.
  • Drag-n-drop the downloaded firmware into the disk.
    That must be the loader is down, you can upgrade this way.

I tried that, but when I press and hold the button while plugging the board, my computer doesn’t recognized it.
I tried to connect to connect the test point BOOT to ground like mentionned here , it worked once, I put the file named lpc11u35_lpc1768_if_mbed_20150128.bin in the drive but now it doesn’t work anymore.

So after trying several times to upgrade the firmware without success, here’s what I did to solve the problem:

  • Connect the test point BOOT to GROUND while connecting the board to the computer
  • A drive named CRP DISABLED appeared. I typed this command : sudo dd if=/path/to/new/firmware/0253_lpc11u35_archpro_0x0000.bin of=/path/to/old/firmware/CRP\ DISABLD/firmware.bin conv=notrunc
  • I unplugged the board
  • I restarted my computer and now it works

Thank you for your help
