hi

 

I have IMX7 DUAL SABRE SD board.

I am trying to run A7  core and M4 core on the board in parallel but I am not able to achieve this Task.

 

In other words I am trying to run LINUX on A7 and FreeRtos on M4 in parallel.

For this I am using the Manual FreeRTOS BSP for i.MX 7Dual Demo User’s Guide.

Chapter 10 RPMsg Ping-Pong FreeRTOS Demo with RTOS API

After performing the necessary steps for M4 Core which are :

1. fatload mmc 0:1 0x7F8000 rpmsg_pingpong_freertos_example.bin

2. dcache flush

3. bootaux 0x7F8000

 

After performing step 3 when I am trying to boot Linux on A7 using the command "boot" then it is not booting.

 

Can any one help me with this issue ?

Can anyone tell me how to run both M4 and A7 in parallel ?

 

regards

Ehsan
