Porting i.MX8MM EVK lf-6.1.22-2.0.0 u-boot

I'm currently trying to port the lf6.1.22-2.0.0 i.MX8MM eval kit to our custom board. Previously we customized the evalkits board files, but we want to use our own files. I changed the UART from 2 to 1, changed the dts, imx8mm_evk2.h & .c and set ,changed the 

IMX_BOOT_UART_BASE = 0x30860000

 
When I startup uuu to flash the uboot into the eMMC I can see the uboot starting up, but when the uboot says "Jump", it is stuck, right after loading the ATF. The U-Boot log is as follows:
 
U-Boot SPL 2023.04-g95b4974dc2-dirty (Dec 28 2023 - 14:43:32 +0800)

I refered to this thread: https://community.nxp.com/t5/i-MX-Processors/Porting-i-MX8MM-EVK-u-boot/m-p/1726956 but the problem didn't work out
I'm using the NXP L6.1.22 BSP, the files work well on lf-6.1.1
