[U-Boot] Ethernet via USB on Sinlinx SinA33

[Quentin Schulz <quentin.schulz@free-electrons.com>]

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
