A recent load did something very strange to two CYW943907AEVAL1F eval boards:  The UART is receiving repeated characters, PRINT char's are being received as input UART characters, and the Wi-Fi is working very odd/broken.

I think some code has quasi-bricked these things.

Is there a way to put the factory load on the devices?  I've been scouring the documentation, but haven't found anything yet.

I don't have a JTAG tool, either.

Thanks!

Thank you for the link.  As it turns out, it wasn't the eval board but rather the serial terminal program "moserial".  For some reason it decided to loop back printed characters back to the UART TX and threw the s/w for a loop.  After switching to "cutecom", the problem is solved.  Phew!
