1710 and USB host

Anyone else having success using the 1710 in USB host mode? Using the latest git kernel, I'm getting the boot messages below. I have a USB key plugged in and it's lighting up, so presumably it's getting powered properly.

Maybe the jumpers aren't set quite right, I don't quite grok the comments around the 'hmc_mode' value in. board-h3.c. In any case, my SW1501 settings are 1=on, and the rest are off.

Thanks for any pointers,

Kevin

Last time I tried it was on a platform where the transceiver wasn't wired up usably, so it was kind of pointless. I expect that's not what you're finding ...

I have no H3, so I can't say whether any of this is sane or not. As I recall, there are two transceivers on that board: OTG, and non-OTG. Ideally both should work. I seem to recall positive reports about using the OTG transciever.

That "init err" means the controlle wasn't responding to basic stuff. Like maybe it wasn't clocked correctly ... you could turn on USB_DEBUG in Kconfig and see if the register dump looks even vaguely sane (like, it should report three ports etc).

Hi Kevin,

We have a custom 1710 based board and I see exactly the same error message. Did you solve your problems with the "init err" on the 1710 platform? If yes, what was the solution. Thanks for any input here.

Best regards,
Stefan
