Earlier i used fel to retrieve script.bin and boot1.header from tablet. I do not have serial port set up in my tablet.
Can i use fel-gpio script to manipulate gpio settings when tablet is in fel mode from my laptop? "fel-gpio: A script which used fel to upload fel-pio to the target, and which then can use the pio utility, and manipulate gpio settings, over fel/usb" If possible, could you advice this procedure? lauantai, 25. tammikuuta 2014 17.37.01 UTC+2 Ian Daniher wrote: > > Something like pio -m 'PB9<1><2><1><1>' ought to enable the 5v rail for > that port, possibly solving your issues. > > You'll need to get 'pio' source from > https://github.com/linux-sunxi/sunxi-tools/blob/master/pio.c and compile > it. > > > On Sat, Jan 25, 2014 at 7:40 AM, SK <[email protected] <javascript:>>wrote: > >> >> >> perjantai, 24. tammikuuta 2014 18.30.06 UTC+2 Ian Daniher wrote: >> >>> Depending upon your kernel and hardware, you may need to configure the >>> port as host-only? >>> >>> > usb_port_type = 1 >>> > usb_host_init_state = 1 >>> >>> On my A20 board with a similar basic configuration, I have to manually >>> enable the pin used for usb_drv_vbus_gpio to enable the 5v rail. >>> >> >> Not work with host-only configuration. >> Nor with powered usb hub. >> >> How can i enable this usb_drv_vbus_gpio pin? >> >> Regards >> Seppo >> >>> >>> >>> On Fri, Jan 24, 2014 at 5:55 AM, SK <[email protected]> wrote: >>> >>>> >>>> >>>> perjantai, 24. tammikuuta 2014 12.18.52 UTC+2 Olliver Schinagl wrote: >>>> >>>>> On 24-01-14 10:18, SK wrote: >>>>> >>>>> >>>>> > Few days ago i finally got my MID S906 booting to Fedora 19r1 >>>>> > But usb not seem to activated.
