Receiving the following error when attempting to enter bootloader mode on CW1200

I successfully updated my CW version number to 5.4 by performing a Git pull through the virtual machine. Now, when attempting to enter bootloader mode through the following block of code ‘import chipwhisperer as cw
scope = cw.scope()
prog = cw.SAMFWLoader(scope)
prog.enter_bootloader(True)’

I receive this error message.

Any help would be greatly appreciated. Thank you.

You can run into that broken pipe error if communication with the CW1200 gets interrupted. The best fix to to unplug + replug.

Thank you, that fixed it. After running the Firmware updater exe, it immediately closes. Is this supposed to be run through a different program? Thank you.

You need to use the firmware updater from the command line with the following usage: firmware_updater.exe COM_PORT CW1200, where COM_PORT is the serial port of the SAM3U bootloader (I believe it shows up as AT91 Bootloader in device manager).
