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@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
