ATK 1 Posted June 24, 2016 Share Posted June 24, 2016 I tried changing script.bin/fex > usbc0 (settings) with many combinations but was not able to get the USB port working as genreal USB host ... so what am i missing ? Target Board :- Banana Pi. Target Os :- 3.4.112 (Armbian_5.10_Bananapipro_Debian_jessie_3.4.112_desktop) Link to post Share on other sites More sharing options...
tkaiser 1643 Posted June 24, 2016 Share Posted June 24, 2016 Did you try to adjust these two usbc0 settings and have a look what happens after exchanging script.bin and a reboot? usb_port_type = 1 usb_host_init_state = 1 On a pcDuino3 Nano it will look like this afterwards: root@pcduino3nano:~# lsusb Bus 001 Device 002: ID 152d:3562 JMicron Technology Corp. / JMicron USA Technology Corp.

ATK 1 Posted June 24, 2016 Author Share Posted June 24, 2016 Hi Tk .. did the modifications as per your last post BUT nothing changes... i`hv connected a wireless dongle for Mouse/KB via OTG cable ... after doing above changes and reboot the dongle is`nt detected ... AFAIK as per the banana Pi H/W schematics ... the port is powered through a chip (SY6280AAC) whose enable signal is "USB0-DRV" which is mapped to SOC`s "PB9" pin ... and inside the fex file this is referred as "usb_drv_vbus_gpio = port:PB09<1><0><default><0>" which again translates to the the USB drive set to Default-LOW .... Though i even tried setting this to "High" in default mode in my previous attempts BUT there was`nt any change ... So i now wonder how to do this.... Edit :- Can you paste here the full listing of [usbc0] of your "pcDuino3 Nano" on which your USB-OTG is working OK in USB-Host mode ? Link to post Share on other sites More sharing options...
tkaiser 1643 Posted June 24, 2016 Share Posted June 24, 2016 Here's whole config regarding OTG: [usbc0] usb_used = 1 usb_port_type = 1 usb_detect_type = 0 usb_id_gpio = port:PH04<0><1><default><default> usb_det_vbus_gpio = "axp_ctrl" usb_drv_vbus_gpio = port:PB09<1><0><default><0> usb_host_init_state = 1 usb_restric_flag = 0 usb_restric_voltage = 3550000 usb_restric_capacity = 5 Did you check dmesg/lsusb? Just as a reference (since the disks were already lying around).

ATK 1 Posted June 24, 2016 Author Share Posted June 24, 2016 Ah ... the major difference between your Fex > usbc0 and the fex accompanying the Armbian (3.4.112 (Armbian_5.10_Bananapipro_Debian_jessie_3.4.112_desktop)) is the line "usb_det_vbus_gpio = "axp_ctrl"" ...it seems that the fex you are using and also the standard fex @ http://linux-sunxi.org/Fex_Guide are having "axp_ctrl" set for " usb_det_vbus_gpio" ... which clearly indicates that here the vbus detection is governed/done by the on board PMU CHIP of banana pi .... BUT the bundled fex with "Armbian_5.10_Bananapipro_Debian_jessie_3.4.112_desktop" is not having this ... so now i will further investigate the issue by setting > usb_port_type = 1 usb_host_init_state = 1 usb_det_vbus_gpio = "axp_ctrl" BTW :- lsusb/dmesg has nothing to say on this .... nothing detected..no activity...

tkaiser 1643 Posted June 24, 2016 Share Posted June 24, 2016 Well, regarding fex file contents... this should be something the hardware vendor is adjusting responsibly to match his device's schematic. Reality differs. We have some fex files in our repo without any adjustments made and some required loads of work (since the hardware vendor did a really bad job trying to describe his hardware). Without double checking schematics you never know. And since you own a device made by @sinovoip you're already lost. They are known for not being able to describe their own hardware correctly (be it fex files or device tree with mainline or even schematics -- they simply don't care and do not even get the idea why that matters) I really liked Banana Pi in the beginning due to being the A20 device with the best GbE throughput. But in the meantime I had to realize that not a single piece of documentation the vendor provides can be trusted. It might be correct or it might be just one of the many copy&paste errors they're famous for. Might apply to BPi too -- won't touch this hardware anytime soon.

zador.blood.stained 764 Posted June 24, 2016 Share Posted June 24, 2016 According to schematics, USB ID detection pin is connected to SoC GPIO PH4 on Banana Pi and Banana Pi M1 and to PH3 on Banana Pro Edit: USB0-DRV (responsible for powering OTG port when OTG cable is connected) is connected to AXP209 GPIO2 on all 3 mentioned boards.

ATK 1 Posted June 24, 2016 Author Share Posted June 24, 2016 OK..I can confirm that the USB0-DRV signal connects to two points on Banana pi PCB .. (1) SOC`s PB9 pin . (2) PMU(AXP209) chip`s PIN no.6 (N_VBUSEN). so now i will try again with the fex settings for usbc0 provided by TK . TK : the board is from Lemaker .. its not a Sinov product .

tkaiser 1643 Posted June 25, 2016 Share Posted June 25, 2016 TK : the board is from Lemaker .. its not a Sinov product . Banana Pi is neither a LeMaker nor a SinoVoip product. I was only talking about 'quality' of documentation / hardware descriptions. I still think LeMaker never did any hardware, their role was to create a community around and they also were agents / reseller (at least last year here in Germany you were only able to get the unfortunate BPi M2 they really have nothing to do with through their sales channels and not SinoVoip's). Banana Pi is a Foxconn product, ODM was done by Xunlong, SinoVoip is currently producing the hardware (and does the most horrible 'support' anyone can imagine, same applies to LeMaker in the meantime too for obvious reasons): http://linux-sunxi.org/User:Tkaiser#Banana_Pi_development_history.2Frumours http://linux-sunxi.org/Banana_Pi https://www.google.com/?q=lemaker+foxconn+inurl:irclog.whitequark.org/linux-sunxi Link to post Share on other sites More sharing options...
