I have a custom PCB using a G400-S that isn’t accepting programming through SAM-BA. Other PCBs in the same batch are working fine. Power supplies all read correctly, and switching USB ports and reinstalling the SAM-BA driver did not help.
Module appears in Devices and Hardware as “Bossa Program Port” even when PA11 (Pin 75) is not pulled to ground on power up. Update.bat fails with the following log file contents:

Any ideas?
Edit:
I’ve now tried to update the rest of my modules. 2 out of 12 could not be updated. One of those modules had 5 V inadvertently applied to the 1.8V and 3.3V supply pins due to a couple of mis-populated linear voltage regulators. This has since been fixed. The 2nd module never had incorrect power applied to it, but is experiencing the same issue.
