Bringing up a new design from 'cold'

Hi All,

 We have just taken delivery of a new board design, using the iMXRT1021. It's currently just populated with the iMXRT1021 and a serial flash on the FlexSPI. The power supplies all come up, and the internal DC-DC is working OK.

QUESTION 1: I would have expected to be able to communicate with it via SWD, but it does not respond. Should I be able to even with an unprogrammed Flash?

QUESTION 2: I need to be able to use the ROM Bootloader via UART. As far as I can tell, Mfg-tool2.exe does not support UART, it only supports USB. Is that correct?

 

Thanks,

 

Chris.
