[linux-sunxi] Re: A20 mainline kernel questions

Hi Andrea, Indeed my song is mono, so that may explain the issue. I also continued to investigate the code from Marcus, which if I understood correctly, is based on your code. I got some successful results also with this code. I think that Marcus wanted to merge the two structures sunxi_priv

[linux-sunxi] Re: A20 mainline kernel questions

Hi Andrea, Good news! I can hear some sounds :). After some discussions with Marcus I've checked I2S pins with logic analyser, the data where at the output but really fast (340kS/s). I decided to replace the I2S driver from Marcus https://github.com/codekipper/linux-sunxi repo with your

Re: [linux-sunxi] A20 touchscreen controller with mainline kernel?

Hi Hans, Thanks for your answer, I saw this after, it wasn't clear to me since no dts file use it. I will use it with TS from olimex which is resistive. Once again I'm really impressed by the sunxi mainlining effort, it's far better than exynos chips... Best regards, Alexis. -- You received

Re: [linux-sunxi] A20 touchscreen controller with mainline kernel?

One other mistake I did, the kernel need Event interface in input section, it wasn't enabled. -- You received this message because you are subscribed to the Google Groups linux-sunxi group. To unsubscribe from this group and stop receiving emails from it, send an email to

[linux-sunxi] Re: A20 mainline kernel questions

Ok thanks for your answer, I don't any screen yet(I'm still waiting for the lime LCD ribbon) so I will play with alsa mixer later. For now I think it may be interesting to play in userspace with i2c and try to speak with the UDA, at least to see if it behaves as expected. I also have a DSLogic

Hi Andrea, Thank you for your answer, I also got one from code keeper with a link to his git repo here. https://github.com/codekipper/linux-sunxi/commits/audio_mainlining After some tweaks(uboot scripts and kernel config for systemd) I successfully booted his kernel. Now I need to do some

[linux-sunxi] Re: A20 mainline kernel questions

I received one answer by mail, init of lcd screen is done by u-boot, I found useful informations by looking in u-boot/configs/ folder and with some grep and looking tablets defconfig files. At least it works on my no-name a20 tablet I will try later on lime2, I didn't received the lcd cable

[linux-sunxi] A20 mainline kernel questions

Hi, I wonder if I can and how to use a olinuxino lime 2 on LCD(via LVDS) with mainline kernel. I'm using fedora since it shows a good upstream policy(I feel) and I use it everywhere. From what I understand, for now u-boot is supposed to init the screen and then kernel just use simple-fb, is it

[linux-sunxi] Re: New firmware for GSL1680

Hi, You can do it with readelf and dd, it's not straight forward, you need to find the symbol offset(table offset + symbol ofset) and size in the file then you dump it with dd. I made a graphical tool to make this easier: https://hephaistos.lpp.polytechnique.fr/redmine/projects/execut/wiki You

Hi, I made a free(GPL) graphical tool to view and extract symbols or sections of an elf file. It may be useful for android firmware extraction(from kernel drivers) and other stuff. I hope it would help somebody. Feedback and contribution are welcome.

Hello everybody, I bought an A20 tablet which doesn't seems to be listed in the wiki device list, I would be happy to contribute in any way to provide all the information about it, I took some PCB pictures, I started to list all the chip inside. At this point I can boot linux on it thank to
