UUU FBK command is not working in imx6s

[hangunwoo]

Hello.

I have a problem with my customized imx6solo board.

I built the yocto(zeus) and fusing the u-boot, kernel image with initramfs.

And also built the initramfs in my zeus yocto.

Everything is okay, but FBK command is not working in UUU.

I changed the kernel image and initramfs in L4.19.35_1.1.0_images_MX6QPDLSOLOX.zip

But  FBK command is still not working.

Is the FBK command not supported on the mx6solo or mx6 series?

here is my uuu script.

-----------------

uuu_version 1.2.39

# boot from u-boot-dtb.imx
# load the u-boot image into the sdram
SDP: boot -f firmware/u-boot-dtb.imx

# burn u-boot to emmc
# macro value is follow the u-boot source
FB: ucmd setenv fastboot_dev mmc
FB: ucmd setenv mmcdev ${emmc_dev}
FB: ucmd mmc dev ${emmc_dev}
FB: flash bootloader firmware/u-boot-dtb.imx
FB: ucmd mmc partconf ${emmc_dev} 1 1 0

# load kernel & initram filesystem
FB: ucmd setenv fastboot_buffer ${loadaddr}
FB: download -f firmware/zImage
FB: ucmd setenv fastboot_buffer ${fdt_addr}

FB: ucmd setenv mfgtool_args ${mfgtool_args} mfg_mmcdev=${emmc_dev}
FB: ucmd run mfgtool_args
FB: acmd ${kboot} ${loadaddr} ${initrd_addr} ${fdt_addr}

# get mmc dev number from kernel command line
FBK: ucmd cmdline=`cat /proc/cmdline`;cmdline=${cmdline#*mfg_mmcdev=};cmds=($cmdline);echo ${cmds[0]}>/tmp/mmcdev
# Wait for mmc
FBK: ucmd mmc=`cat /tmp/mmcdev`; while [ ! -e /dev/mmcblk${mmc} ]; do sleep 1; echo "wait for /dev/mmcblk${mmc} appear"; done;

FBK: Done

This is uuu verbose log.

Okay. I solved this issue in myself. :smileyhappy:

It caued by UDC.

I guess udc is not properly configured in my kernel defconfig and dts file.

The below steps are required for UDC to work properly.

u-boot defconfig

--------------

CONFIG_CI_UDC=y

CONFIG_CMD_FASTBOOT=y
CONFIG_USB_FUNCTION_FASTBOOT=y
CONFIG_FASTBOOT_UUU_SUPPORT=y
CONFIG_FASTBOOT=y
CONFIG_FASTBOOT_BUF_ADDR=0x12000000
CONFIG_FASTBOOT_BUF_SIZE=0x10000000
CONFIG_FASTBOOT_FLASH=y
CONFIG_EFI_PARTITION=y

Kernel defconfig

--------------

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

imx6dl-sabresd.dts

--------------

&usbotg {
    dr_mode = "peripheral";
    status = "okay";
};

And i will upload my kernel defconfig for your reference.

Regards.

Hi Han

seems fbk is working only with android as described in

sect.5.6 FBK: Android fastboot protocol uuu manual

https://github.com/NXPmicro/mfgtools/releases/download/uuu_1.2.135/UUU.pdf 

Best regards
igor

Thanks for your reply.

I think your comment is wrong.

FB command is the Android fastboot protocol too. But it works fine.

FBK command is the same. It's not support only with android.

I think it depends on initramfs or kernel.

Regards.
