Hi,
I want to create a bootloader project to start up both M7 and A53 core,how can i do for it? Some doc or idea?
I find the Bootloader Integration Example in the Platform_Software_Integration_S32R45 don't start A53 core, or I didn't understand it correctly.
Can you help me?
Hi aiweixin,
The bootloader integration example does demonstrate booting of the A53 core, the boot sequence is: POR -> HSE (NXP BootROM FW) -> M7_0 (bootloader application) -> A53 (u-boot -> Linux). Please follow the bootloader example user guide and go through the steps to import, build and run the example and you will see the outcome of having M7_0 and all A53 cores enabled.
We can help you understand it better but please be specific with your questions; which parts do you have trouble with?
Hi Gary,
I have tried to do it as following these steps:
1) import the bootloader integration example on S32DS, and open the .mex file to generate code;
2) build it successfully.
3) build the linux, and generate linux files(uboot, image, dts, rootfs);
4) use s32ft.exe to upload uboot to flash(the address is same as BootSources_A53_uboot in step 1);
5) debug bootloader project by S32 Debug Probe.
But, there is nothing output on the COM (Serial port).
where do i make some mistakes?
Hi aiweixin
我看了你的截图,猜测你应该是中国人,
请问一下,你这边同时启动M7 和 A53 成功了吗?
我的问题和你相识,我用的是S32G-VNP-RDB2的板子,深度参考了附件的文档,M7这边的bootloader以及M7这边的APP都已经起来了,但是M7启动A53(FIP)的时候没有相应,不知道问题出在哪里。
下面是我发的贴子,但是感觉NXP这边回复的跟我问的相差很大,所以目前还问题还没有解决
