Good morning Biser,
In the TRM," Table 26-30 pins used for SPI boot "are listed and also there is "NOTE : That all the pins might not be driven at boot time" similarly
"Table 26-36 pins used for UART boot" are listed ans there is a "NOTE : Alll the pins might not be driven at boot time".
kindly , let me know the pins used for SPI boot and for UART boot and also the pins which are not driven at boot time in each of the mode. and also how to take care of those pins which are not been driven at boot time.
Regards,
Mamatha
