melka Posted August 30, 2019 Posted August 30, 2019 Hi everyone, I'm trying to get armbian running on an A20 based board. Been through the wikis (armbian and sunxi-linux) but I get a problem that is hard to figure out (for me). The board is an old tablet, know as Inet K100 (mine is branded Storex), and I'm trying to get the legacy kernel running on it to get a desktop install with LCD etc... Using sunxi-tools, I was able to get a fex file from the board.

Is there anything special to do with the kernel configuration for an A20 based board, like disabling some stuff ? Or is it more likely due to a bad defconfig or dts file ? I thought that the dts file was not needed for the legacy kernel, so do I really need it ? Thanks for taking the time to answer my questions Full boot log below.

melka Posted August 30, 2019 Author Posted August 30, 2019 So, I might be going into the right direction. Since the kernel panic happened just after trying to load the USB stuff (ohci), I built the kernel without the OHCI and EHCI modules and I was able to boot into a debian minimal terminal appearing on the LCD. From an old linux-sunxi mailing list post, it looks like I might have the wrong pin definition. My boot log showed those lines, so I'll check into it. <6>ehci_hcd: USB 2.0 'Enhanced' Host Controller (EHCI) Driver <6>ohci_hcd: USB 1.1 'Open' Host Controller (OHCI) Driver WRN:L430(drivers/usb/host/sw_hci_sunxi.c):ERR: gpio_request failed WRN:L816(drivers/usb/host/sw_hci_sunxi.c):ERR: alloc_pin failed WRN:L430(drivers/usb/host/sw_hci_sunxi.c):ERR: gpio_request failed WRN:L816(drivers/usb/host/sw_hci_sunxi.c):ERR: alloc_pin failed If someone could answer a question about the build process in armbian, that would help. Since I'm trying to build the legacy (3.4.113-sun7i) kernel, shouldn't the .fex file be enough ? Do I have to write a defconfig and / or dts file ? Thanks
melka Posted August 31, 2019 Author Posted August 31, 2019 Hi everyone, So I guess my board is working now and I have the answer to my question : you only need to modify the fex file is you're building the legacy kernel. My previous boot error (the kernel panic) was because the usb_drv_vbus_gpio for [usbc2] was undefined. Modified the fex file with this line to get it to boot with all usb ports working : usb_drv_vbus_gpio = port:PH03<1><0><default><0> I can boot to the desktop, now it's a matter of building modules etc... for the various components of this board.
