I checked it with some Allwinner A33 Tablets from eBay or Amazon, the touch isn't working at the moment, but I hope I have time to check it in the future.
I had to disable the pwm_bl module, otherwise the screen will go black while boot.Įcho blacklist pwm_bl>/etc/modprobe.d/pwm.conf MODULES_NEXT="hci_uart gpio_sunxi rfcomm hidp bonding spi_sun7i 8021q a20_tp g_serial gsl圆80 gc0312 gc2145 rtl8150" MODULES="hci_uart gpio_sunxi rfcomm hidp bonding spi_sun7i 8021q a20_tp g_serial gsl圆80 gc0312 gc2145 rtl8150" android 4.4 q88 allwinner a33 quad core tablet pc dual camera bluetooth wifi,10pcs/lot dhl free Irulu brand expro 7 tablet pc dual core android 4.2 tablet. #MODULES="hci_uart gpio_sunxi rfcomm hidp bonding spi_sun7i 8021q a20_tp" # depending of board and resolution use a defconfig file from sources/u-boot/v2018.05/configsīOOTCONFIG="q8_a33_tablet_1024圆00_defconfig" Hi Markbirss, I checked it again with current build and it's working with module "g_serial" add to boards/nf
Log1.txt Edited Decemby specific tablet you are using ? Are you able to boot a Armbian build image directly from sdcard now? I checked a lot of things, but I can't find a solution to solve this problem, the Kernel is booting this way, until it can't find the SD Card. Please check your kernel config and/or bootloader. done, booting the kernel.Įrror: unrecognized/unsupported machine ID (r1 = 0x00001029). So I want to debug the Armbian Kernel with serial output and I used fastboot for it, I'm booting into fastboot with "adb reboot bootloader" and then I'm sending the bootimage with fastboot ( first I created a image with mkimage with and without dtb file)įastboot -c "console=ttyS0,115200" boot uImage I was checking and this Image is booting the Tablet, with Kernel 4.1x. The Serial connection is only in the SD Adapter and I cant use it if I'm booting from it, or is there a possibility ? The SD Card is booting with a nice screen output but only to Kernel Boot, then the screen freezes. I created an new board, based on the nf with BOOTCONFIG="q8_a33_tablet_1024圆00_defconfig" and build a Debian Stretch Image with mainline Kernel 4.13 / 4.14. Check steps to install driver for your Android Tablet.UPDATE: Today I build it again and now it's working, I think someone has change something. The foremost issue which we have experienced among users is that their tablet does not get identified by the pc.Īctually, USB driver installation has not been installed. Download the ISO image & then connect your Tablet to the PC.
Download the Firmware or Flash file for your Allwinner A33 Tablet PC with tools needed to perform the flashing.
