Hi team,
I am using the imx6d board. While flashing the image into the board, i am getting success till
# This command will be run when i.MX6/7 i.MX8MM, i.MX8MQ
SDP: boot -f u-boot-dtb.imx
# This command will be run when ROM support stream mode
# i.MX8QXP, i.MX8QM
SDPS: boot -f u-boot-dtb.imx
# These commands will be run when use SPL and will be skipped if no spl
# SDPU will be deprecated. please use SDPV instead of SDPU
# {
SDPU: delay 1000
SDPU: write -f u-boot-dtb.imx -offset 0x57c00
SDPU: jump
# }
# These commands will be run when use SPL and will be skipped if no spl
# if (SPL support SDPV)
# {
SDPV: delay 1000
SDPV: write -f u-boot-dtb.imx -skipspl
SDPV: jump
# }
# use uboot burn bootloader to eMMC
# becaue difference chip, offset is difference
# you can use kernel to do that for specific boards
FB: ucmd setenv fastboot_dev mmc3
FB: ucmd setenv mmcdev ${emmc_dev}

# get mmc dev number from kernel command line
# Wait for emmc
FBK: ucmd while [ ! -e /dev/mmcblk%mmc% ]; do sleep 1; echo "wait for /dev/mmcblk%mmc% appear"; done;
after till below FBK command is not working.
# get mmc dev number from kernel command line
# Wait for emmc
FBK: ucmd while [ ! -e /dev/mmcblk%mmc% ]; do sleep 1; echo "wait for /dev/mmcblk%mmc% appear"; done;
i have done the changes in the uboot and kernel as per UUU.pdf.
below is the u-boot changes i have done.
CONFIG_CMD_FASTBOOT=y
CONFIG_USB_FUNCTION_FASTBOOT=y
CONFIG_USB_GADGET=y
CONFIG_USB_GADGET_DOWNLOAD=y
CONFIG_USB_GADGET_MANUFACTURER="FSL"
CONFIG_USB_GADGET_VENDOR_NUM=0x0525
CONFIG_USB_GADGET_PRODUCT_NUM=0xa4a5
CONFIG_CI_UDC=y # UDC need change according system, ←-
some system use CONFIG_USB_DWC3, some use CONFIG_USB_CDNS3
CONFIG_FSL_FASTBOOT=y
CONFIG_FASTBOOT=y
CONFIG_FASTBOOT_BUF_ADDR=0x83800000 # Address need change according ←-
system, generally it can be the same as ${LOADADDR}
CONFIG_FASTBOOT_BUF_SIZE=0x40000000
CONFIG_FASTBOOT_FLASH=y
CONFIG_FASTBOOT_FLASH_MMC_DEV=1
CONFIG_EFI_PARTITION=y
CONFIG_ANDROID_BOOT_IMAGE=y
below kernel changes.
CONFIG_USB_CHIPIDEA=y
CONFIG_USB_CHIPIDEA_UDC=y
CONFIG_USB_CHIPIDEA_HOST=y
CONFIG_USB_GADGET=y
CONFIG_USB_MASS_STORAGE=y
CONFIG_USB_FSL_USB2=y
CONFIG_USB_CONFIGFS=y
CONFIG_USB_CONFIGFS_MASS_STORAGE=y
CONFIG_USB_CONFIGFS_F_FS=y
Please suggest on this .
