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@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
