Hello,

I try with slimbootloader and u-boot payload to read on mmc, i have this issue:

=> mmc info sdhci_set_clock: Timeout to wait cmd & data inhibit sdhci_set_clock: Timeout to wait cmd & data inhibit sdhci_set_clock: Timeout to wait cmd & data inhibit CMD_SEND:0 ARG 0x00000000 sdhci_send_command: MMC: 0 busy timeout. RET -70

My setup is CRB cherryboard with alderlake N with slimbootloader and u-boot. With config slimbootloader_defconfig:

CONFIG_X86=y CONFIG_ENV_SIZE=0x1000 CONFIG_DEFAULT_DEVICE_TREE="slimbootloader" CONFIG_VENDOR_INTEL=y CONFIG_TARGET_SLIMBOOTLOADER=y # CONFIG_USE_CAR is not set CONFIG_BOOTSTAGE=y CONFIG_BOOTSTAGE_REPORT=y CONFIG_BOOTDELAY=3 CONFIG_AUTOBOOT_KEYED=y CONFIG_AUTOBOOT_STOP_STR="s" CONFIG_AUTOBOOT_KEYED_CTRLC=y CONFIG_USE_BOOTCOMMAND=y CONFIG_BOOTCOMMAND="usb start ; if usb storage ; then if fatload usb 0:1 $loadaddr boot.scr; then source $loadaddr ; fi ; else if mmc list; then if fatload mmc 0:1 $loadaddr boot.scr ; then source $loadaddr ; fi ; fi ; fi" CONFIG_SYS_CONSOLE_INFO_QUIET=y CONFIG_BOARD_EARLY_INIT_R=y CONFIG_LAST_STAGE_INIT=y CONFIG_HUSH_PARSER=y CONFIG_SYS_PBSIZE=532 # CONFIG_BOOTM_PLAN9 is not set # CONFIG_BOOTM_RTEMS is not set # CONFIG_BOOTM_VXWORKS is not set CONFIG_CMD_MEMINFO=y CONFIG_CMD_LSBLK=y CONFIG_CMD_MMC=y CONFIG_CMD_BKOPS_ENABLE=y CONFIG_CMD_MMC_SWRITE=y CONFIG_CMD_USB=y CONFIG_CMD_DHCP=y CONFIG_BOOTP_BOOTFILESIZE=y CONFIG_CMD_PXE=y CONFIG_CMD_EXT2=y CONFIG_CMD_EXT4=y CONFIG_CMD_FAT=y CONFIG_CMD_SQUASHFS=y CONFIG_CMD_FS_GENERIC=y CONFIG_CMD_ZFS=y CONFIG_EFI_PARTITION=y CONFIG_ENV_OVERWRITE=y CONFIG_SYS_RELOC_GD_ENV_ADDR=y CONFIG_USE_BOOTFILE=y CONFIG_BOOTFILE="bzImage" CONFIG_TFTP_TSIZE=y CONFIG_BOOTP_SERVERIP=y CONFIG_USE_ROOTPATH=y CONFIG_REGMAP=y CONFIG_SYSCON=y # CONFIG_ACPIGEN is not set CONFIG_LBA48=y CONFIG_SYS_64BIT_LBA=y CONFIG_SUPPORT_EMMC_BOOT=y CONFIG_MMC_IO_VOLTAGE=y CONFIG_MMC_UHS_SUPPORT=y CONFIG_MMC_HS400_ES_SUPPORT=y CONFIG_MMC_HS400_SUPPORT=y CONFIG_MMC_TRACE=y CONFIG_MMC_DW=y CONFIG_MMC_SDHCI_ADMA=y # CONFIG_PCI_PNP is not set CONFIG_SYS_NS16550_PORT_MAPPED=y CONFIG_CONSOLE_SCROLL_LINES=5 # CONFIG_GZIP is not set
