Since FW R12 , it is not allowed to run the reset.cwe:

Swiflash -r broken with release 12 on wp77xx?

Hey, After a board issue (see topic https://forum.mangoh.io/t/cannot-access-mangoh-yellow-wp7702/4848/27) I think there is a problem with the swiflash command and its -r option for recovery mode. With fw R12, this tool doesn’t work, I had to downgrade to R11 to be able to use it. Thanks
