[iMX6UL] BSP Build error when enable CONFIG_CMD_USB_MASS_STORAGE in u-boot-imx

[jimhuangtw]

Hi iMX experts,

I am trying to enable "ums" command in u-boot-imx on i.mx6ultralite-evaluation-kit

After I enabled CONFIG_CMD_USB_MASS_STORAGE=y in mx6ul_14x14_evk_defconfig 

and re-build u-boot-imx, I got the build error as below.

Could you give a suggestion for enabling "ums" command in u-boot?

BSP uboot-version:
U-Boot 2017.03-nxp/imx_v2017.03_4.9.11_1.0.0_ga+ga2fea67

BSP build code method:

repo init -u git://git.freescale.com/imx/fsl-arm-yocto-bsp.git -b imx-morty
MACHINE=imx6ulevk source fsl-setup-release.sh -b build
bitbake fsl-image-gui

Thanks,

Jim

Take a look at configs/pico-imx6ul_defconfig. It is a mx6ul based board that has CONFIG_CMD_USB_MASS_STORAGE=y.
