It is a common thing to boot a Linux system (see the Raspberry Pi) from a micro SD card. It is not that common for a microcontroller. The NXP i.MX RT ARM Cortex-M7 fills that gap between these two worlds. No surprise that it features a ROM bootloader which can boot from a micro SD card.

In “First Steps with the NXP i.MX RT1064-EVK Board” I mentioned that the board kit came with a camera module, but it was unclear to me which module was included in the kit. I know it now: it is the ON Semiconductor MT9M114 :-).

I noticed on Mouser.com that there is a new i.MX RT1050 board: the EVKB one. I have used the EVK (the one without the ‘B’) for several weeks (see “MCUXpresso IDE V10.1.0 with i.MX RT1052 Crossover Processor” and “Adding a Rocktech Capacitive Touch LCD to the NXP i.MX RT1052 EVK“). I needed anyway a second board, so I ordered that EVKB from Mouser, and after some delay and waiting it arrived on my desk. So far this boards seems to be a better one:
