Hello,
I'm currently developing on RP2350 and test the Secure Boot via OTP that is presented in the datasheet. I saw that you can disable debug interface with the CRIT1 bits via picotool but, is USB interface also able to be disabled? Secure boot would be only preventing to install new unsigned firmware, but you can actually download the flash content with picotool via USB interface right?
Is there any way to prevent that apart of denying physical access to the interface?
Thanks for your time
