Boot: ROM code may hang in UART boot mode during data transfer

Details:

Due to advisory i2310, it is possible for ROM code execution to hang during UART boot. The software workaround presented in i2310 is not implemented in ROM, and thus an erroneous timeout interrupt can be triggered in an unexpected state. This can prevent the ROM from being able to clear this interrupt and therefore hang.

This can manifest any time UART boot mode is used or when UART is used as the boot interface to enable production flows such as UniFlash or programing eFuses with OTP Keywriter.

Workaround(s):

None. Another boot interface should be used.
