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. You may visit the product page, but usually, Allwinner does not provide many details beyond the hardware specs.UPDATE: Today I build it again and now it's working, I think someone has change something.
Besides Android support, another operating system called HybridOS is being developed partially based on Huawei HarmonyOS, more specifically OpenHarmony. Allwinner designed an R818 evaluation board, but I cannot find it for sale anywhere yet. That also means an Android 10.0 SDK, and support for Allwinner wireless chips namely Allwinner XR829 802.11 b/g/n WiFI 4 & BT4.2, and Allwinner AW859A 802.11 a/b/g/n/ac WiFI 5 & BT 5.0. Those different processor names happen because of Allwinner structure with business units that take care of different customers, with for instance a Tablet business unit (A-series now merged in T-Series), and a “Smart Speaker/Smart Home” business unit (R-Series). If the specifications look similar it’s because Allwinner R818 is actually the same chip as Allwinner A133 tablet SoC.
