Deep Dive w/Scott: iMX RT Flash#adafruit
53Today I answer any questions folks have, show the flash changes for RP2040, most other ports, show off the iMX RT dev boards from NXP and discuss the iMX RT flash changes. Visit the Adafruit shop online - http://www.adafruit.com
I’m sponsored by Adafruit to work on CircuitPython. Support them, and by extension me, by purchasing hardware from https://adafruit.com
Chat with me and lot of others on the Adafruit Discord at https://adafru.it/discord.
Deep Dive happens every week. Normally Fridays at 2pm Pacific but occasionally shifted to Thursday at 2pm. Typically goes for two hours or more. Questions are welcome.
Next week will be on Friday. The week after on Friday I’ll be speaking at the Open Hardware Summit in the morning and then streaming the 1 year anniversary in the afternoon at the normal time.
