AM6442: Industrial SDK boot issue using running via remoteproc

Hi Team,

We are trying to build industrial sdk(ind_comms_sdk_am64x_11_00_00_13) for ethercat_slave_beckhoff_ssc_demo for r5f1_0 booting via A53 linux kernel using remoteproc framework. With ethercat stacks added, we could able to generate am64-main-r5f1_0-fw file for r5f1_0 core and placing in /lib/firmware/mcubenchmarkdemo, and boot via a53 using echo cmd, faced error -22, With one of TI support thread assistance(https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1289532/am6442-problems-loading-demo-project-into-r5f-from-linux), I changed the memory mapping from MSRAM to DDR, and then I could see the linux prints as
[ 60.960808] remoteproc remoteproc2: powering up 78400000.r5f
[ 60.965177] remoteproc remoteproc2: Booting fw image am64-main-r5f1_0-fw, size 62868
[ 60.967636] remoteproc remoteproc2: remote processor 78400000.r5f is now up

added syscfg and linkercmd for your ref.
syscfg.txt.txt
linker_cmd.txt.txt
but from r5f fw, main is not executing in thread, on debugging it crashes in startup, main is not hit, can you provide solution on this.

Hi Team,

Can I get updates on this any time sooner??

Hello Sankar,

You will need to make modifications to the R5F project in order to get it working alongside the Linux A53 cores. Please refer to this FAQ:

 [FAQ] AM64X: How to combine R5F PRU_ICSSG Ethernet with Linux A53 cores 

I would suggest keeping the SRAM allocation for your Ethernet FIFOs. SRAM access is much faster than DDR access.

You can see an example of allocating SRAM for the R5F core in the Multicore academy here:
