Hi @stefancinipeanu,
Thank you very much Stefan for your clear and prompt reply. I see, and your screenshot indeed shows that MBDT 1.3.0 only support the i.MX RT1024 MCU, not my i.MX RT1020 MCU. I was thinking that since both MCUs basically share the same instruction set (ISA), then both will be treated similarly by the MBDT compiler (especially since even older generation i.MX RT1011 is supported).
So I think my solution is to just purchase an i.MX RT1024-EVK.
But maybe I will try one last thing before: if I click the "build" button on Simulink for that example on the Quick Guide (ignoring that "select OpenSDA driver" step), this will make MATLAB coder generate a .bin file in the example folder, which I can just copy-paste into the mass storage that appears when I plug in my i.MX RT1020EVK board to PC, this -I read somewhere- has the same effect as deploying that example into the board. I tried it actually once, but seems like I only managed to override the default blinky demo pre-loaded on the board. I will try again with some other examples maybe, and if you have any tips that can make my EVK work with Simulink blocks please do not hesitate to share anything, it's all useful. Thanks a lot!!
Best Wishes,
Youness
