17:59 <Viciouss> I have a Galaxy Note 10.1 tablet which is based on the Exynos 4412 and I try to get some uart output with a mainline kernel. There are quite some things already covered in the base dts and with a little bit of help from the midas config I could get the display to light up but now I'm stuck as there is nothing happening. The lcd driver in the Samsung sources is deeply hooked into MDNIE and S3C and I don't get anything displayed.

17:59 <Viciouss> Unfortunately there is no output on the serial but from S-Boot and can't figure out why it immediately cuts off after switching to the kernel code.

18:00 <Viciouss> The Samsung kernel too doesn't seem to output anything to uart. Did I miss something somewhere?

18:05 <Viciouss> I currently believe that it's the 30pin connector that's causing the issue but as I'm quite new to the linux kernel, I'm still trying to wrap my head around everything

18:38 <Viciouss> I was looking into the issue for so long and then I found the cause just 30 minutes after asking... there was one GPIO that needed to be configured and now I have a serial! I'm so happy right now. The display will still be an issue though but one step at a time :D
