u-boot가 커널 부팅에 멈췄습니다

내 목표 설정:

SOC: STM32H743 (Cortex m7 single core)
Internal Flash: 2MB
Board: Waveshare CoreH7XXI
On-board DRAM: 8MB, Start_Address: 0xd0000000, Size_in_bytes: 0x7A1200
SDCARD: 1GB

Bootloader: mainline u-boot (only I've modified the device tree and added my board files, almost everything is default)
kernel:     mainline linux (compiled with stm32_defconfig configuration + some tweaks in menuconfig)

내 콘솔(PC) 설정:

OS: Ubuntu 20 LTS on windows10 WSL2
Text Editor: VSCode (Visual Studio Code)
Debug Probe: STLink V2
Debug Software: Openocd + gdb-multiarch integrated in VSCode
