Re: [linux-sunxi] [PATCH] musb: sunxi: Ignore VBus errors in host-only mode
Hey Hans, I've tried getting your musb stuff working on a cubietruck, but i don't seem to see this patch on your linux-sunxi/sunxi-wip branch on github? Is your github branch fully functional at the moment? What I have done so far, is build the kernel using sunxi_defconfig and enabled USB_MUSB_SUNXI with its dependancies (musb isn't enabled there by default): USB_SUPPORT [=y] && USB_MUSB_HDRC [=y] && ARCH_SUNXI [=y] && NOP_USB_XCEIV [=y] && PHY_SUN4I_USB [=y] && EXTCON [=y] && GENERIC_PHY [=y] Selects: SUNXI_SRAM [=y] I changed the dts from dr_mode='otg' to dr_mode='host', a) we only need host mode anyway (the id pin isn't properly connected) and b) I got an error about an known dr_mode before and this was the quick and easy way. Dmesg produces the following related to musb. [1.691062] usb_phy_generic.0.auto supply vcc not found, using dummy regulator [1.691445] musb-hdrc: ConfigData=0xde (UTMI-8, dyn FIFOs, bulk combine, bulk split, HB-ISO Rx, HB-ISO Tx, SoftConn) [1.691453] musb-hdrc: MHDRC RTL version 0.0 [1.691467] musb-hdrc: 11/11 max ep, 5184/8192 memory [1.691543] musb-hdrc musb-hdrc.1.auto: MUSB HDRC host driver [1.691553] musb-hdrc musb-hdrc.1.auto: new USB bus registered, assigned bus number 5 [1.692470] hub 5-0:1.0: USB hub found [1.692529] hub 5-0:1.0: 1 port detected [1.699956] sunxi-rtc 1c20d00.rtc: setting system clock to 2015-08-06 07:59:08 UTC (1438847948) [1.704733] usb0-vbus: disabling [1.765695] ldo4: disabling [1.808351] ldo3: disabling [1.848769] vcc5v0: disabling [1.848774] vcc3v0: disabling The usb_phy_generic missing shouldn't be too bad? But the usb0-vbus being disabled obviously might be related to the musb port not working? What causes this though? I went through all the musb patch series mails but don't recall seing anything special being needed. If there are fixes missing in the sunxi-next stuff that could explain this, could you be so kind and push your latest work so I can try it? Thanks Hans!
