Hi ,
Our board used two TDA4VM SoC and QNX OS.
We developed the PCIE feature for communicate between two SoC and it used the physical memory address "0x8_C000_0000" for 1G size.
From the following link: 8.9. Understanding and updating SDK memory map for J721E — Processor SDK RTOS J721E
I understand that the following files need to be modified in the Linux system. Is it necessary in the QNX system?
-
Linker command files for various RTOS CPUs
./c66x_1/linker_mem_map.cmd ./c66x_2/linker_mem_map.cmd ./c7x_1/linker_mem_map.cmd ./mcu2_0/linker_mem_map.cmd ./mcu2_1/linker_mem_map.cmd
-
Memory map .h file that is used by various system init, mmu/mpu init functions
./app_mem_map.h
-
Linux DTS file snippets to copy/paste into linux DTS/DTSO files
./k3-<soc>-rtos-memory-map.dts
-
A human readable html table showing the different memory map sections
./system_memory_map.html
