Hello,

Without USB vendor commands, the SPI flash cannot be accessed and hence firmware cannot be modified. The flash needs to be de-soldered and erased through a different mechanism before using it with FX3 for booting.

Best regards,

Hello,


The firmware that is running on FX3 needs to have a vendor command to send erase commands to the SPI flash.
