    In the i.MX RT1060 docs, they mention
    On-chip RAM(1MB) :
    * 512 KB FlexRAM shared between ITCM/DTCM and OCRAM
    * Dedicate 512 KB OCRAM

    So I think the RAM1 (FlexRAM) can be partitioned...

    The imxrt1062.ld file seems cryptic to me. I tried to change

    _heap_end = ORIGIN(RAM) + LENGTH(RAM);

    to

    Although the simple example above works but the library I am using seems have new/malloc which is taking up some memory in the RAM2.
    Is there any way to move the heap from RAM2 to RAM1?

    After looking into the core files I found removing DMAMEM allows to use almost all the RAM2. Most of the places DMAMEM is undefined when CPU speed is below 30MHz. I did a quick testing by changing...

    Thanks for your suggestion! I will look into Teensy 4.1. For the time being, I am trying to keep the data within 512 KB (in the 2nd block) but I faced another issue.

  10. Teensy 4.0: assign large chunk of data in RAM

    Hi,

    The Teensy 4.0 has two memory blocks each of 512KB. I have a requirement to assign a single uint_8 array of size 550KB. The first memory block is already occupied with 300KB of data but have...
