I have no indication though that the UDC core itself is in any way different to the ones on other i.MXs.

I have no indication though that the UDC core itself is > in any way different to the ones on other i.MXs. I have tested usage device mode on i.MX27. It works (Patch for PCM-038 will be sent), but driver(?) does not work for me on i.MX51... Executing is freeze at dr_controller_setup (drivers/usb/gadget/fsl_udc.c). Now I trying to check for missing clocks, but not sure about this since we enable all clocks at start... So, if anyone can test this feature on i.MX51 it will be helpful.

If there's a problem it's more likely that the usbmisc registers are not correctly initialized, so it probably won't help to test on another board Sascha -- Pengutronix e.K. | | Industrial Linux Solutions | http://www.pengutronix.de/ | Peiner Str. 6-8, 31137 Hildesheim, Germany | Phone: +49-5121-206917-0 | Amtsgericht Hildesheim, HRA 2686 | Fax: +49-5121-206917-5555 | _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 6+ messages in thread

It is neccesary to set an additional bit in MX5_UTMI_PHY_CTRL_0. #define MX5_OTG_PHYCTRL_OTG_XCVR_BIT (1 << 7) ... v |= MX5_OTG_PHYCTRL_OTG_XCVR_BIT; ... But now it still works only with "fsl-udc" driver, not with "chipidea". I will continue work on it. --- _______________________________________________ barebox mailing list barebox@lists.infradead.org http://lists.infradead.org/mailman/listinfo/barebox ^ permalink raw reply [flat|nested] 6+ messages in thread
