SK-AM64B: IPC failed on SK-AM64B (HS-FS Version)

Part Number: SK-AM64B
Other Parts Discussed in Thread: SYSCONFIG, UNIFLASH

Hello,

I am trying IPC in SK-AM64B board (HS-FS Version) which is red in colour and is marked with a "M2" sticker (the user guide in the website mentions M1 sticker).

CCS version: 12.2.0

MCU+ SDK version: AM64x 08.05.00.24.

I am trying the IPC between the two cores r5f0_0 and r5f0_1 .through the following steps:

1. Importing projects ipc_rpmsg for r5f0_0 and r5f_01 in CCS projects. r5f0_0 is main core.

2. Making changes to sysconfig of both projects by disabling IPC of other processors except r5f0_0 and r5f_01.

3. Making changes to .c files of both projects by removing the other remote core IDs except r5f_01.

4. Building both the projects succesfully.

5. Creating Target Configuration by selecting Connection as "Texas Instruments XDS110 USB Debug Probe" and Board or Device as "AM64x".

6. Launching Target configuration.

7. Connecting the r5f0_0 and r5f_01 cores and doing a CPU Reset on both of them.

8. Loading the respection xxx_ti_arm_clang.out files on both the cores.

9. Starting the execution on both the cores one by one.

I get the following output on the UART terminal after executing all the above steps:

[r5f0-1] 1.058137s : [IPC RPMSG ECHO] Remote Core waiting for messages from main core ... !!!
[IPC RPMSG ECHO] Message exchange started by main core !!!
ERROR: RPMessage_send:272: [IPC RPMSG] Message send to remote core 1 @ 13 end point failed due to invalid parameters !!!
ASSERT: 0.514852s: ../ipc_rpmsg_echo.c:ipc_rpmsg_echo_main_core_start:175: status==SystemP_SUCCESS failed !!!

Could you please help me resolve this issue?

Thanks in Advance

Hi Guenter,

Thank you for your detailed steps.

I tried the steps mentioned by you on AM64B HS FS. I used MCU SDK Version 8.05.24 itself, but I am on CCS 12.3(CCS Version should not be a concern at all)

I was able to run the IPC example between r50_0 and r50_1.

Here is the log on the COM port:

On top of the IPC message logs, as you can see I have all the cores initialized via SBL Null.

My question is: Have you done SOC Initialization using SBL Null ?

I have successfully followed the SOC Initialization via UART Uniflash and SBL null, but I am unable to do the SOC Initialization via CCS Scripting.

Does this affect the succesful execution of IPC?

Thanks in advance

Hi Guenter,

Thanks for the reply.

I will try the CCS scripting myself and check if there is any problem doing SOC Initialization.

Hi Guenter,

Apologies for the delayed response as I was on leave.

I tried to do the SOC Initialization using CCS Scripting. It worked, I feel like you might be getting the dev boot mode wrongly on the HS FS SK-AM64B.

Please look at the attachment of successful execution & the boot mode pins position as well.

Boot Mode Pins(DEV BOOT MODE):

The reason I am sending the photo of the boot mode pins is because I think you have got the dev boot mode set up wrongly.

Please let me know if it helps.

Hello Vaibhav, I am able to run IPC and I am getting the same output as you. Thank you for helping me out
