Hi, I am trying to get Ethernet to work through the USB port of the Sinlinx SinA33 on U-Boot to use TFTP to get the kernel and dtb files.
However, I am getting 'data abort' when using dhcp or tftp after adding: #define CONFIG_USB_HOST_ETHER #define CONFIG_USB_ETHER_ASIX to include/configs/sunxi-common.h and checking CONFIG_USB_EHCI_HCD as told in the documentation [1] I tested this configuration with the C.H.I.P. and it is working well. Steps to reproduce: 1) Add the following lines to include/configs/sunxi-common.h: #define CONFIG_USB_HOST_ETHER #define CONFIG_USB_ETHER_ASIX 2) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- Sinlinx_SinA33_defconfig 3) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- menuconfig 4) Check CONFIG_USB_EHCI_HC and save configuration 5) make ARCH=arm CROSS_COMPILE=arm-linux-gnueabihf- -j$(nproc) 6) Prepare SDCard: sudo dd if=u-boot-sunxi-with-spl.bin of=/dev/sdX bs=1024 seek=8 7) Boot the board and run dhcp or tftp 8) Get 'data abort' and board gets reset (ethact is also not defined) The log file is attached. Thank you, Quentin [1] https://github.com/lentinj/u-boot/blob/master/doc/README.usb#L132
