Linux: Access firmware RAM



Tool/software: Linux

Hi,

Hi,

I am using GNU Tools ARM Embedded (arm-none-eabi-gcc.exe with -march=armv7e-m) for my source code together with TI CSL drivers, I am loading the firmware via remoteproc driver in kernel.

  • IPU1 is located at 0x90000000 (32MB)
  • IPU2 is located at 0x92000000 (32MB)

I want access (read/write) from IPU1 (0x90000000) to the RAM of IPU2 (0x92000000)? Is it possible (I don't want shared RAM)?  If yes, where do I need to configure it (rsc_table, dts-file, linux driver)?

Regards,

Andreas
