Hi experts,
I use the uuu to download image to imx8mm evk board.
If I use : uuu -b emmc_all uboot.bin image to download the whole image , it will succeed. So I think it means the hardware environment is no problem.
But if I use uuu example_kernel_emmc.uuu to download the kernel/dtb/rootfs, it is always stuck at UTP: Waiting for /dev/utp to appear .
From my understanding, in this step, it has downloaded the kernel_image and fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot into the DDR RAM. then boot the kernel_image.
But fails to recognize the new usb device.
my fsl-image-mfgtool-initramfs-imx_mfgtools.cpio.gz.u-boot is copied from NXP's demo image-LF_v5.10_2.0.0_images_IMX8MMEVK.
and my kernel is built from rel_imx_5.4.24_2.1.0.tar.bz2, use the imx_v8_defconfig.
in this config , the usb related config are enabled :
CONFIG_USB_LIBCOMPOSITE=y
CONFIG_USB_F_MASS_STORAGE=y
CONFIG_USB_F_FS=y
CONFIG_USB_CONFIGFS=y
CONFIG_USB_CONFIGFS_MASS_STORAGE=y
CONFIG_USB_CONFIGFS_F_FS=y
my uuu version is uuu (Universal Update Utility) for nxp imx chips -- libuuu_1.4.149-0-gab2f4c7
. as the uuu FBK supports the two Vid/Pid.
FBK: 0x066f 0x9afe
FBK: 0x066f 0x9bff
I grep 066f in the linux code ,can't find any usb vid defined to 066f.
Does the uuu support to download sperate kernel/rootfs to imx8mm?
What should I do to address this problem?
Anyone can suggest on this is appreciated.
