[U-Boot] i.MX6Q SabreLite: Ethernet does not work at Gigabit speed

[Wolfgang Grandegger]

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):

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.
