Bootloader starts M7_0 program error

youke — Thu, 19 Dec 2024 03:12:06 GMT

hi NXP,

I successfully used the bootloader based on AN13750 to initiate communication between the IPCF of three M7 cores and A53;
Version used: linux bsp41、Integration_Reference_Examples_S32G2_2023_06、SW32G_IPCF_4.9.0_D2310
Now I want to test LLCE communication, and I have done the following tests:
Open the can2can DS project, modify the LD file to match the space occupied by "IPCF_Sample multi_instance S32G274A_M7-0", compile and add IVT and other information, burn QSPI, and I caught the can signal on the llce_can line;
I used the can2can program to replace IPCF_Samplemulti_instance S32G274A_M7-0 and started can2can through bootloader, but I couldn't capture the relevant signal on the can line.
May I ask where a DS or EB routine needs to be modified in order to boot through bootloader?

The following figure shows the jump information when burning can2can separately, compared to the jump information when bootloader starts

hi,youke

Thank you for contacting us and details.
1. In the basic CAN2CAN program, do you capture relevant signals on the can line?
2. Have you changed the addresses of Reset_Handler and int_sram_c0 in the Bootloader? The addresses of CAN2CAN program need to be changed to those in CAN2CAN program before CAN2CAN program can be started.
3. In addition, in order to better help you with the test, could you please provide the Integration_Reference_Examples_S32G2_2023_06 project? I will try my best to help you.

hi joey，

1. I caught the CAN signal on the llce_can line；
2. I modified ResetHandler and int_stram_c0 on the bootloader. The following image shows the ld file of my can2can;

3.
Wait a moment, I will send out the relevant project

thanks,

hi,youke

I have received your attachment. Can you provide a complete Integration_Reference_Examples_S32G2_2023_06 project.

In addition, regarding the following information, CAN2CAN is loaded in the description, and the signal cannot be measured on the line. Has your A core been started?

"I used the can2can program to replace IPCF_Samplemulti_instance S32G274A_M7-0 and started can2can through bootloader, but I couldn't capture the relevant signal on the can line."
