Hi,

I just realized that I cannot download files on a Gitabit Ethernet network. I'm getting timeouts:

MX6QSABRELITE U-Boot > boot
Using FEC device
TFTP from server 172.16.0.1; our IP address is 172.16.0.100 Filename 'wolf/uImage-mx6q-mainline'.
Load address: 0x10800000
Loading: error frame: 0x4fd76ca0 0x00000804
T error frame: 0x4fd77f00 0x00000804

Before I start digging, is this a known issue?

Wolfgang.

Hi Wolfgang,

This is/was an issue on the first batch of Sabre Lites.

It stemmed from the proper connection of pin 9 on the ethernet jack (it shouldn't be connected):

https://wiki.linaro.org/Boards/MX6QSabreLite#Gigabit_Ethernet_issue

If you're not in a position to de-solder the pin, contact me off-list and we'll arrange for a swap.

Regards,

Eric

Also, I recently posted a patch for mainline u-boot. I'll repost with you and Joe Hershberger in cc.

Thanks for the patch. It help to some extend but I'm still getting timeouts. I need to fix the hardware as well, as Eric suggested.
