[U-Boot] Ethernet via USB on Sinlinx SinA33

[U-Boot] Ethernet via USB on Sinlinx SinA33

[Quentin Schulz]

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

Are you perhaps building u-boot with gcc6 ? There are some known issues
when building u-boot with gcc-6, which look pretty much like this.

Is the ethernet adapter connected to a regular usb host port, or to
the otg port ?

Hans

No, I'm building with gcc-5:
$ arm-linux-gnueabihf-gcc --version
arm-linux-gnueabihf-gcc (Ubuntu 5.2.1-22ubuntu1) 5.2.1 20151010

The Ethernet adapter is connected to the regular USB host port.

Hmm, then maybe we are missing some cache flusing somewhere in the ehci code?

Otherwise I would not know what the issue might be.

So I've been debugging some armv7 cache issues lately and I've come
up with the following fix:

https://patchwork.ozlabs.org/patch/605967/

This might very will fix your issue too. If not we're likely missing
some cache flushing / invalidation in the usb driver for your usb
host controller.

Hans

I actually tried uboot-sunxi repository (and then checked out on merge
commit in master for this repository) and it is working as expected: I
get Ethernet over USB.

I tested with master (43d3fb5c0609a76409e7859a2a5800670c7b5bd2) and I
first get a reset of the board when starting USB (before I can enter
U-Boot command line) and then after the reboot, U-Boot hangs on starting
USB (still before the command line).

I did a git bisect on master and it returned this commit:
http://git.denx.de/?p=u-boot.git;a=commit;h=3f9f8a5b83f8aec40c9f4ee496046a695e333c45

Tell me if I can help in any way.

Quentin

Ah, that is fixed by this commit:

http://git.denx.de/?p=u-boot/u-boot-usb.git;a=commitdiff;h=cfb3f1cd0e022711d69ff040884357b8410865ef

A pullreq for which was send this morning, so this should be fixed
in master as soon as the u-boot-usb pull-req gets merged.
