Thanks for that tip but it made no difference to me.
I need to look deeper into that problem.

Just a bit of a context here.
I'm playing with ARC SP board which consists of 2 parts:
 [1] Baseboard with all peripherals and their connectors
 [2] Daughterboard with CPU and DDR

Baseboard is connected to CPU-board via AXI tunnel. 

And when CPU-board is the one with ASIC based on ARC770
that runs at 700 MHz I see USB 2.0 working perfectly fine.

But if I use CPU-board that sports FPGA with ARC HS38 CPU
running at 75 MHz I see the first asynchronous tarnsaction
on US 2.0 never happens. 

In particular in ehci_submit_async() after we enable async. schedule
setting CMD_ASE command STS_ASS gets set but then token's status
stays active forever i.e. following is always true:
->8-
QT_TOKEN_GET_STATUS(token) & QT_TOKEN_STATUS_ACTIVE
->8-

Note USB host controller, phy and usb dongle are exactly the same.
And USB 1.1 (OHCI) works perfectly fine at the same time.

Any ideas what could be wrong?

Try defining CONFIG_EHCI_IS_TDI , that _might_ help.

I remember seeing that stuff multiple times before, but it might be a different 
issue. It was usually triggered by some sort of corruption during the transfer.
On ARM, that was often caused by cache issues.

Connect signaltap or chipscope ? :)

Try adding #define DEBUG at the first line of common/usb.c , so we can get some 
more debugging info. Also adding the same into common/usb_hub.c helps.

[U-Boot] [PATCH] axs103: add support of generic OHCI USB 1.1 controller

2015-12-16 Thread Alexey Brodkin

This commit adds support of USB 1.1 storage media on AXS103 board.
For some yet unknown reason USB 2.0 doesn't work on AXS103 board issuing
messages like this:
>8---
AXS# usb start
starting USB...
USB0:   USB EHCI 1.00
