Hi,
I'm trying to get the USB OTG port working on my device (S3C6410 board),
but am running into problems.
This board doesn't have a 48Mhz clock, so I set the reference clock in
the USB PLL to a 12Mhz external crystal (see patch).
Still, I'm having trouble getting it to work; I'm seeing these messages
(see attachment for full log):
s3c-hsotg s3c-hsotg: s3c_hsotg_rx_data: FIFO 8 bytes on ep0 but no req
(DxEPCTl=0x00028000)
hub 1-0:1.0: connect-debounce failed, port 2 disabled
This looks like the hardware is configured correctly, but the
currently-in-use gadget isn't setting up an EP0 RX transfer?
I've tried Mass Storage, serial, Ethernet, ... gadgets and they all give
the same errors.
Any hints/pointers would be welcome!
Thanks,
Maurus Cuelenaere

Hi,
I'm trying to get the USB OTG port working on my device (S3C6410 board),
but am running into problems.
This board doesn't have a 48Mhz clock, so I set the reference clock in
the USB PLL to a 12Mhz external crystal (see patch).
Still, I'm having trouble getting it to work; I'm seeing these messages
(see attachment for full log):
s3c-hsotg s3c-hsotg: s3c_hsotg_rx_data: FIFO 8 bytes on ep0 but no req
(DxEPCTl=0x00028000)
hub 1-0:1.0: connect-debounce failed, port 2 disabled
This looks like the hardware is configured correctly, but the
currently-in-use gadget isn't setting up an EP0 RX transfer?
I've tried Mass Storage, serial, Ethernet, ... gadgets and they all give
the same errors.
Any hints/pointers would be welcome!
Thanks,
Maurus Cuelenaere

In fact, I once used 12Mhz external crystal, after setting PHYCLK
right, both USB 1.1 as host and 2.0 as gadget can work. The kernel
version I used is 2.6.28.

You say the kernel version you used is 2.6.28, I'm betting you weren't
using Ben Dooks' driver then and this was Samsung's tree?
The kernel that is currently shipped with the device I'm porting for
(SmartQ 7) is using 2.6.24, which also has Samsung's patches applied
(and uses other drivers than in mainline).
AFAIK there are 2 (?) 'main' trees floating around with Samsung patches:
2.6.24 and 2.6.28, then there are 2.6.29 and 2.6.31 (and newer) trees
which contain patches from a mix of both and mainline.
What I'm looking for is getting everything to work with *mainline*
drivers, so in the end I can push the SmartQ boards to mainline.

Maurus Cuelenaere

Its sad, they have switched to a different SoC in later SmartqV series
and are phasing
out the SmartQ-5,7 series(I cudn't get one). best of luck, though.
