  1. Okay, so i wanted to try the dev and legacy kernels. Is it possible the dev kernel for bananaPi is also not supported by the installer? So to check them out i need to remove and add the packages as mentioned before manually? Regards, Paul EDIT: I tried switching to DEV, and its also not working there (4.5.0-rc3). No dmesg musb logs at all (and no ethernet for some reason). So next step would be trying the legacy kernel.
  2. Hi there, I sent the M2 back and got me a bananaPRO, hoping it would work out of the box with the vanilla kernel. Problem is, it does not work. I am on 4.4.3-sunxi now, and by default, the DR_MODE was "host". In this setting i get musb logs in dmesg. BUT if i change it to "otg", theres no more musb logs in dmesg AND modprobe g_hid still fails with the error device not found. There should be musb logs in dmesg regardless of the DR_MODE, right? Can you give me some more advice? Shall i switch to dev? Or try the legacy version? Regards, Paul
  3. Hi, I will now try to switch to the debug kernel manually using apt-get. To do so, i will first remove "linux-*-next-sunxi" (*=dtb|firmware|headers|image) : sudo apt-get remove linux-dtb-next-sunxi linux-firmware-next-sunxi linux-headers-next-sunxi linux-image-next-sunxi linux-jessie-root-next-bananapim2 (root tweaks) has no dev counterpart in the repo (only linux-jessie-root-bananapim2 without any tags). Both have latest version 5.00, so which one shall i choose? The existing next one or the one without a declarator (linux-jessie-root-bananapim2)? and then i will install the dev counterparts: sudo apt-get install linux-dtb-dev-sunxi linux-firmware-dev-sunxi linux-headers-dev-sunxi linux-image-dev-sunxi As the repo also includes a custom uboot for dev, i will install it too (but theres nothing to uninstall as the uboot package is not installed atm): sudo apt-get install linux-u-boot-bananapim2-dev Then I will reboot and hopefully still have a working system, but switched to dev kernel, right? And the selection of the root fs tweaks package does not even matter maybe because of the same version? Regards, Paul
  4. Hi, I found this patch for A31s musb specifically: https://patchwork.ozlabs.org/patch/492959/ But it should already be inside your code, as the "reset" DT field was added by the patch. But wait, at least the patched notes state "reset" , but the devtree has "resets". Might that be a reason for it not to work? Regards, Paul
  5. hmm, your installer does not list the banana pi m2. so i'll have to switch manually? does that happen by me uninstalling the old packages and installing the dev one?
  6. Hi Igor, thanks for your lightning fast reply! by latest kernel you mean switching to the dev kernel, right? And also, the modprobe sunxi didnt throw any errors, but also no change. If the musb subsystem worked, there would be something about that in dmesg, right? So as long as I don't get these dmesg musb messages, any later changes (like modprobing the sunxi thingy) won't bring success, if i am not mistaken with my limited linux knowledge. I will try the dev kernels this evening. Regards, Paul
  7. hi all, I read the other topic about "Banana Pi USB OTG" in preparation of trying to enable USB OTG (device mode actually) on a Banana Pi M2 (A31s). When my Pi arrived yesterday, I performed the following steps: downloaded latest Jessie Vanilla image from http://www.armbian.com/banana-pi-m2/, burned to SD, installed (without any problems) ran apt-get update & upgrade I now have "uname -r" -> "4.4.1-sunxi", and "dpkg -l" lists "linux-*-next-sunxi" (*=dtb|firmware|headers|image) in version 5.01. I was happy to find that the g_* kernel modules were present (with the exception of g_zero), but root@bananapim2:~# modprobe g_hid modprobe: ERROR: could not insert 'g_hid': No such device OK, so i checked the Device Tree file /boot/dtb/sun6i-a31s-sinovoip-bpi-m2.dtb To decompile it, I ran: dtc -I dtb sun6i-a31s-sinovoip-bpi-m2.dtb -O dts -o sun6i-a31s-sinovoip-bpi-m2.dts When checking the DTS file, i found the musb controller, which was disabled: usb@01c19000 { compatible = "allwinner,sun6i-a31-musb"; reg = <0x1c19000 0x400>; clocks = <0x10 0x18>; resets = <0x11 0x18>; interrupts = <0x0 0x47 0x4>; interrupt-names = "mc"; phys = <0x1d 0x0>; phy-names = "usb"; extcon = <0x1d 0x0>; status = "disabled"; }; So I changed the "disabled" into "okay" and added dr_mode="otg" to the DTS: usb@01c19000 { compatible = "allwinner,sun6i-a31-musb"; reg = <0x1c19000 0x400>; clocks = <0x10 0x18>; resets = <0x11 0x18>; interrupts = <0x0 0x47 0x4>; interrupt-names = "mc"; phys = <0x1d 0x0>; phy-names = "usb"; extcon = <0x1d 0x0>; dr_mode = "otg"; status = "okay"; }; Then i compiled it back into the DTB file: dtc -I dts sun6i-a31s-sinovoip-bpi-m2.dts -O dtb -o sun6i-a31s-sinovoip-bpi-m2.dtb After a reboot, the modprobe problem is still there. Also in dmesg, nothing shows up about musb: root@bananapim2:/boot/dtb# dmesg | grep "usb" [ 3.203261] usbcore: registered new interface driver usbfs [ 3.203316] usbcore: registered new interface driver hub [ 3.203380] usbcore: registered new device driver usb [ 3.388457] ehci-platform 1c1a000.usb: EHCI Host Controller [ 3.388487] ehci-platform 1c1a000.usb: new USB bus registered, assigned bus number 1 [ 3.388738] ehci-platform 1c1a000.usb: irq 31, io mem 0x01c1a000 [ 3.404952] ehci-platform 1c1a000.usb: USB 2.0 started, EHCI 1.00 [ 3.405229] usb usb1: New USB device found, idVendor=1d6b, idProduct=0002 [ 3.405241] usb usb1: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 3.405250] usb usb1: Product: EHCI Host Controller [ 3.405259] usb usb1: Manufacturer: Linux 4.4.1-sunxi ehci_hcd [ 3.405267] usb usb1: SerialNumber: 1c1a000.usb [ 3.406519] ohci-platform 1c1a400.usb: Generic Platform OHCI controller [ 3.406544] ohci-platform 1c1a400.usb: new USB bus registered, assigned bus number 2 [ 3.406657] ohci-platform 1c1a400.usb: irq 32, io mem 0x01c1a400 [ 3.469165] usb usb2: New USB device found, idVendor=1d6b, idProduct=0001 [ 3.469177] usb usb2: New USB device strings: Mfr=3, Product=2, SerialNumber=1 [ 3.469185] usb usb2: Product: Generic Platform OHCI controller [ 3.469194] usb usb2: Manufacturer: Linux 4.4.1-sunxi ohci_hcd [ 3.469202] usb usb2: SerialNumber: 1c1a400.usb [ 3.470269] usbcore: registered new interface driver usb-storage [ 3.506676] usbcore: registered new interface driver usbhid [ 3.506682] usbhid: USB HID core driver [ 3.724966] usb 1-1: new high-speed USB device number 2 using ehci-platform [ 3.875545] usb 1-1: New USB device found, idVendor=1a40, idProduct=0101 [ 3.875558] usb 1-1: New USB device strings: Mfr=0, Product=1, SerialNumber=0 [ 3.875567] usb 1-1: Product: USB 2.0 Hub [ 4.174962] usb 1-1.3: new low-speed USB device number 3 using ehci-platform [ 4.314881] usb 1-1.3: New USB device found, idVendor=046a, idProduct=0011 [ 4.314902] usb 1-1.3: New USB device strings: Mfr=0, Product=0, SerialNumber=0 [ 4.327046] input: HID 046a:0011 as /devices/platform/soc@01c00000/1c1a000.usb/usb1/1-1/1-1.3/1-1.3:1.0/0003:046A:0011.0001/input/input0 [ 4.385300] hid-generic 0003:046A:0011.0001: input,hidraw0: USB HID v1.11 Keyboard [HID 046a:0011] on usb-1c1a000.usb-1.3/input0 So is musb currently still disabled for a reason on BPi-M2 (Igor mentioned such in the other thread in March) ? Or am I doing something wrong? Hardware setup wise, I just connected the microUSB to my notebooks A port (power seems sufficient) using a normal cable. Ah yeah, and big thanks Igor for this awesome distro and the community for bringing insight about usb OTG mode. regards, Paul
