This is not a problem directly about Teensy. I searched and asked in NXP forum without getting a clear answer.
When in XIP mode, can processor like rt1064 write to the same flash chip itself? Some people say yes, as far as you can locate that part of the code in memory and stop all the interrupts. Some say no, only if there are more than one flash chips or a dual port flash.
May I ask how this problem is handled on Teensy 4.1? According to memory map in https://www.pjrc.com/store/teensy41.html, the code is running from the same flash chip that has a LittleFS system.
Thanks.
