Hi list,

I want to use the ums command to access the SD card of a A20-OlinuxIno-Lime board via usb-org cable. For that I start the CPU in FEL mode, download the u-boot-sunxi-with-spl.bin file by sunxi-fel tool. I do this FEL mode boot for preparation of an Einstein A20 board, which has only an internal MMC. I run on uboot serial console:

=> ums 0 mmc 0 UMS: LUN 0, dev 0, hwpart 0, sector 0x0, count 0x1dc000 Controller uninitialized g_dnl_register: failed!, error: -6 g_dnl_register failed

Sorry to jump in such an old thread, but as this is still an issue in current master (~ 2020.07-rc2) I don't think it hurts.

This error is typically encountered with Allwinner SOCs when: CONFIG_CMD_USB_MASS_STORAGE=y but CONFIG_USB_ETHER is not set.

Enabling CONFIG_USB_ETHER=y workarounded the issue for me, as reported also elsewhere: http://patchwork.ozlabs.org/project/uboot/patch/CAEXMXLTm9bhX7aAub+MaZGBdw2c... http://linux-sunxi.org/U-Boot/USB_Mass_Storage#Prerequisites
