Some Questions about A53 Image Preparing for S32G3 Multicore Application

[lihongjun_01]

Dear NXP, 

I am practicing multicore application on S32G-VNP-RDB3 board. 

After several question & reply interactivities on NXP community, I have successfully built: the A53 u-boot and ATF(in Ubuntu VM), the 2 M core IPC multi-instance examples(IPCF_Example_multi_instance_S32G399_M7_0/1, in S32DS3.5) and the M core bootloader. I also generated S32G boot image using IVT_TOOL successfully. At last I burned all the images to the board using S32 flash tool. All operations are strictly according to AN13750, with details and tips told my NXP technical supporters. 

But when I set the board boot from nor flash and turn it on, no A53 boot log appears on the terminal. I think the issue is caused by wrong SD card image. 

According to the steps introduced by section 4 of AN13750, I have to download the prebuilt image of Linux BSP, write it to SD card using cygwin, update fip.bin and fip.s32 file by the newly generated ones, replace the kernel image and dtb image in the SD card. But in S32G3 Linux BSP 35.0 User Manual, it seems that no Cygwin operation and similar file copying steps are required.  

So the questions are: 1) for S32G3 chip and RDB3 board, are there any changes for above SD card prepare steps? 2) How to build IPC images and deploy them to SD card?

Thanks.

Hi Li Hongjun

Hope you are doing well.

1)  for S32G3 chip and RDB3 board, are there any changes for above SD card prepare steps?

A.  Let me first explain about Cygwin:- it is a Unix-like environment and command-line interface for Microsoft Windows. It is terminal emulator on which you run some of linux command. if you are write sdcard from window os you have to use this tool.

In linux os 'dd' command used to write image on sdcard. in BSP user manual there are just steps mentioned using dd command which is for linux os. so no any name like Cygwin mentioned.

The image writing steps mentioned in bsp user manual is just for normal image write( Without Enabling Multicore Application ). if any want use enabling Multicore Application then follow AN13750. here some file copying steps are required so.

2) How to build IPC images and deploy them to SD card?

A.  Are you asking about to build ipc application ?
