S32G2 Linux bsp emmc boot

Hi,nxp team:
Recently I am learning how to start EMMC, referring to Johnli's article "S32G_EMMC_Application". I have some questions. If I use bsp29 and follow the steps in the manual, I can start emmc, but if I use other versions, such as bsp38, the same steps will not start emmc. Since I am not very familiar with the u-boot instructions, I don't know which instructions I need to change when switching bsp. Please help me, thank you.The following is the link to the article I referred to：

Hi, @Joey_z :

What I want to know is the address you marked in the red box. How do you confirm it. Is it written in that document? Please guide me. Thank you.

hi，jiajun_cheng

Thank you for your reply.

You can refer to the S32G2_LinuxBSP_38.0_User_Manual.pdf document Chapter 4, refer to the address. The different addresses that BSP29 and BSP38 into DDR are related to the Image itself. When BSP38 burn DDR through SD card, it is very likely that the low address space has been occupied, resulting in a conflict.

Hope it can help you!
