Hi Nicolas,
I have not tested a RT1020 lately. My board is pack becaue I am moving in a fey days. It will be a several weeks before I can l look at it. Possibly Dave Marples github @mubes can lend a hand.

However, I get a hardfault at boot which I haven't been able to solve by myself and would appreciate some help to figure out if i'm doing something wrong or if there is an issue with the configuration for this board. I have been able to get the following information : - Debugger is pointing at mm_initialize.c line 141 after hardfault (I've included a picture with registers values if that's useful) - When i enable Memory manager and Scheduler debug, I get the following logs : nx_start: Entry mm_initialize: Heap: name=Umem, start=0x20201da1 size=4294959711 mm_addregion: [Umem] Region 1: base=0x20201f00 size=4294959360 I assume that size is the issue but i haven't been able to fix it myself. If that matters : I have been using MCUXpresso IDE to flash the board and I'm using the board is SCH-29856 REV A3 Thanks ! Nicolas
