CONFIG_USB_MUSB_TUSB6010=m affects the code inside musb_hdrc inspite of tusb6010 not loaded at all. When I disable CONFIG_USB_MUSB_TUSB6010 in my configuration, everything works fine. After the following modification, usb seems to be semi-working with CONFIG_USB_MUSB_TUSB6010=m. diff --git a/drivers/usb/musb/musb_regs.h b/drivers/usb/musb/musb_regs.h index 03f2655..a146b9a 100644 --- a/drivers/usb/musb/musb_regs.h +++ b/drivers/usb/musb/musb_regs.h @@ -234,12 +234,7 @@ #define MUSB_TESTMODE 0x0F /* 8 bit */ /* Get offset for a given FIFO from musb->mregs */ -#if defined(CONFIG_USB_MUSB_TUSB6010) || \ - defined(CONFIG_USB_MUSB_TUSB6010_MODULE) -#define MUSB_FIFO_OFFSET(epnum) (0x200 + ((epnum) * 0x20)) -#else #define MUSB_FIFO_OFFSET(epnum) (0x20 + ((epnum) * 4)) -#endif I am still testing, and suspect that musb_readb/musb_writeb stuff in musb_io.h is also the subject. The question is how to fix all this in correct way. -- With best regards, Matwey V.
