Hi Eric Li

Please describe brief about your issue

As per your description you want to run llce sample app from uboot ? after then you want work continue in u-boot. but before run sample and after testings, identified clock initialization  you are getting shell like zombie ?

Thanks caring, let me clarify for you,

[Eric] Yes, accurately speaking I run ipcf sample by uboot firstly, and then integrate llce into it.
but before run sample and after testings, identified clock initialization you are getting shell like zombie ?
[Eric] added llce function (Mcu_InitClock(McuClockSettingConfig_0);) to ipcf main function, uboot hang up.

Hi Eric Li

I think you are coping llce function (Mcu_InitClock(McuClockSettingConfig_0);)  in the ipcf main function. LLCE and IPCF both sample app configured different. please read clocking system of s32g first. please understand booting and multicore booting are deep technical projects especially the complex multi-core system like S32G. refer IPCF and Platform Software_Integration S32G.  please let us know if you have more quarry.

Thanks caring.

Based on our testing today, the image file is bigger aftering integrating with llce code, which may be the reason of hanging up uboot shell,  and then could you plz tell me how to correct linker config to make it run right way.

Thanks

Hi Eric Li

Are you sure the bigger image be the reason of hanging up u boot shell ? did you run LLCE sample app( Without edit) without hanging up u boot shel ? please let us know

there may be most possibility is the clock conflict between M7 and A53. we suggest you find the conflict points via constant debugging.

Thanks Buddy,
Basically run llce sample manually (no use debugger) and made uboot hang-up
