重现步骤
I design board base on 01Studio CanMV.
About Hardware:
- I edit PQ pin Lpddr4 (I edited lpddr4_init_32_swap_2667.c and rebuild u-boot).
- Memory eMMC ->MMC0
- SDCard > MMC1
期待结果和实际结果
When i config boot from MMC1 (SD card , BOOT0=1 BOOT1=1), i get error boot:
U-Boot SPL 2022.10 (Apr 23 2025 - 21:23:28 +0700)
lpddr4 2660 - SilverAI-2
