Hello,
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
It seems that the drivers/usb/musb-new/sunxi.c is not initialized. The
devicetree has a node that should match:
usb at 01c13000 {
compatible = "allwinner,sun4i-a10-musb";
reg = <0x1c13000 0x400>;
clocks = <0x2 0x0>;
interrupts = <0x0 0x26 0x4>;
interrupt-names = "mc";
phys = <0x2b 0x0>;
phy-names = "usb";
extcon = <0x2b 0x0>;
allwinner,sram = <0x2c 0x1>;
status = "okay";
dr_mode = "otg";
};
My config is:
cat defconfig
CONFIG_ARM=y
CONFIG_ARCH_SUNXI=y
CONFIG_MACH_SUN7I=y
CONFIG_DRAM_CLK=384
CONFIG_MMC0_CD_PIN="PH1"
CONFIG_I2C1_ENABLE=y
CONFIG_SATAPWR="PC3"
CONFIG_DEFAULT_DEVICE_TREE="sun7i-a20-olinuxino-lime"
CONFIG_AHCI=y
# CONFIG_SYS_MALLOC_CLEAR_ON_INIT is not set
CONFIG_SPL=y
CONFIG_SPL_I2C_SUPPORT=y
# CONFIG_FASTBOOT is not set
# CONFIG_CMD_FLASH is not set
# CONFIG_CMD_FPGA is not set
CONFIG_CMD_USB_MASS_STORAGE=y
# CONFIG_SPL_DOS_PARTITION is not set
# CONFIG_SPL_ISO_PARTITION is not set
# CONFIG_SPL_EFI_PARTITION is not set
CONFIG_ETH_DESIGNWARE=y
CONFIG_SUN7I_GMAC=y
CONFIG_AXP_ALDO3_VOLT=2800
CONFIG_AXP_ALDO4_VOLT=2800
CONFIG_SCSI=y
CONFIG_USB_EHCI_HCD=y
CONFIG_USB_MUSB_GADGET=y
CONFIG_SYS_USB_EVENT_POLL_VIA_INT_QUEUE=y
CONFIG_USB_GADGET_DOWNLOAD=y
# CONFIG_USB_ETHER is not set
Is the ums working for Allwinner CPUs, or is there some further configuration
needed that I have not figured out?
Br,
Frank

First of all - I do not have any experience with Allwiner...

Could you paste output of the console after defining #define DEBUG on
top of drivers/usb/gadget/g_dnl.c ?
It seems like your musb UDC is not initialized in your board
(CONFIG_USB_MUSB_GADGET=y).
Please check if you call it at your board file.

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:
