ipc 3.x MessageQApp test on AM572x evaluation module

Hi Yordan,

I download ti-processor-sdk-rtos-am57xx-evm-02.00.00.00-Linux-x86-Install.bin.

IPC_Install_Guide_Linux.pdf is included in ipc_3_40_01_08 (in ti-processor-sdk-rtos-am57xx-evm-02.00.00.00-Linux-x86-Install.bin)

I read the IPC_Install_Guide_Linux.pdf .

I believe the document provided in ipc_3_40_01_08 is common for various platforms. So the part where omapl138 is mentioned is just an example, you should replace with the relevant platform instead.

It is different on AM572X.

1. rproc_mem linux boot-up parameter, I don't know the address, I use readelf to get the  entry point messageq_single.xe66, then guess the address is 0x90000000.

So I use rproc_mem=32M@0x90000000.

2. How to load the dsp firmware, omapl138 has module parameter da8xx_fw_name to specify firmware name, but am572x doesn't the parameter. I traced the omap_remoteproc.c, but no ideal. I rename dra7-dsp2-fw.xe66 to load the messageq_single.xe66 .

It is convenience that a document describes the part.

IPC_Install_Guide_Linux.pdf don't mention the cortex m4 part, I don't know how to test cortex m4 by IPC 3.x .

Dear all,

I inserted debug message in MessageQapp, it is in MessageQ_open() while loop.

Does it change message successfully?
