Hi, my name is Franco, and I'm interested in adding this new device to the sunxi-boards repo in order to be able to build a new kernel and get rid of android. My idea is to use this tablet as a control center for some smart devices in my house.
So far I was able to retrieve most of the device information. I have both bootinfo.txt and script.fex files with the extracted dram parameters. I wasn't able to extract information about the touchscreen and other sensors because it seems that android is now broken. I can only boot recovery interrupting u-boot and manually loading the recovery partition. The so called, normal boot, ends up with the device stuck on the bootlogo and on serial I can only see the "Starting kernel..." text. I've tried to manually change the loglevel hoping to see some kind of messages from the kernel but nothing. I also haven't found a way to read boot logs on u-boot, so I think android is done for the moment. In theory, I now have to add support to u-boot, but for that, I need a device tree, and I don't really know how to write one. My previous experiences with dtb and kernel compilations are with the WonderMedia's 8650 soc. I only copied text that I gathered from different messages and pasted it on the dtb file, and things just worked. I want to learn how to write dtb files, but in the meaning time, I was wondering if someone could guide me a little bit on what route should I take. The device page is here <https://linux-sunxi.org/X-View_Proton_Tab_2>, with all the information I was able to find, and I also attach both bootinfo.txt and script.fex files to see if you can tell me what already written dtb file is the closest one to what my device needs. Thanks in advance. Cheers, Franco. -- You received this message because you are subscribed to the Google Groups "linux-sunxi" group.
