Many examples use UART4 as debug output, in my particular design, UART4 are in an inconvenient location, so need to switch to another U(S)ART. In CubeMX following is available. From left to right, BOOT ROM, TF-A and OPTEE. currently I have USART1, 2 and 6 as an alternative.
Questions:
1.only USART1 shows OPTEE, why is this ?
2 . USARTS 1 does not have a checkbox for A7 BOOT ROM. what does this imply for boot ? No messages ?
3. Are there any other pro/cons for using one of these U(S)ART ?
