Hi Developers,
I am struggling with the u-boot for the Banana Pi BPI-P2 Zero. I used this defconfig but it has problems with at least the mmc card:
CONFIG_ARM=y CONFIG_ARCH_SUNXI=y CONFIG_DEFAULT_DEVICE_TREE="sun8i-h3-bananapi-m2-plus-v1.2" CONFIG_SPL=y CONFIG_MACH_SUN8I_H3=y CONFIG_DRAM_CLK=408 CONFIG_MMC0_CD_PIN="" CONFIG_MMC_SUNXI_SLOT_EXTRA=2 # CONFIG_SYS_MALLOC_CLEAR_ON_INIT is not set CONFIG_PREBOOT="" # CONFIG_SYS_DEVICE_NULLDEV is not set CONFIG_SPL_STACK=0x8000 CONFIG_SYS_PBSIZE=1024 CONFIG_SUN8I_EMAC=y CONFIG_USB_EHCI_HCD=y
This is the output from serial: U-Boot SPL 2022.10 (Oct 28 2022 - 20:34:40 +0200) DRAM: 512 MiB Trying to boot from MMC1
