RTX Mailbox in specific RAM locations

Chris Carter

I'm using an NXP LPC1768 and RTX 4.7.0.

I was using this code to store a large buffer in AHBSRAM0:

__attribute((section("AHBSRAM0"),aligned)) BufferStruct Buffer[BufferCount];

And I'd like to switch and use a Mailbox in RTX.

I'm wondering if it is possible to cause osMailAlloc to create mailbox items in specific RAM locations?

For example, if i have a scatter file with the sections below could i use IRAM2 for the mailbox?

  RW_IRAM1 0x100000C8 0x7F38  {
   .ANY (+RW +ZI)
  }
  RW_IRAM2 0x2007C000 0x4000  {  ; RW data for Mailbox
   .ANY (AHBSRAM0)
