02:30 <hexagonwin> Hello, I just woke up and is continuing research (?) of the phone. I just found out this (https://u-boot.denx.narkive.com/7vv58bTn/patch-0-9-arm-exynos-add-tm2-board-support) which is a u-boot support patch of tm2. If then, can I change this in some way and maybe load to my device? Or would it be impossible to know since it's unknown what was done

02:30 <hexagonwin> on s-boot? Thanks..

02:31 <hexagonwin> (Sorry for saying just phone, I mean the exynos5433 attached Samsung Galaxy Note 4 S-LTE (SM-N916 / tre3calte) )

09:14 <PabloPL> hexagonwin: Hi. I did played with that patch some time ago and after some small changes go it to work on 7578 (or maybe it was 8890 - don't remember now). It was flashed in place of stock kernel (so it was loaded by stock sboot).

09:14 <hexagonwin> Ah, nice. Thanks!!

09:15 <hexagonwin> Btw, is the 7578 (Or 8890) that you got to work normally in 64bit mode, or was it also in 32bit mode? PabloPL

09:16 <PabloPL> hexagonwin: I was trying them in 64 bit mode (build kernel for arm64), but they have some broken firmware so some hacks to dts were needed (for clocks)

09:17 <hexagonwin> Which device were you doing that for? Or maybe just some test board?

09:18 <hexagonwin> PabloPL In this device the firmware may be 32bit only, maybe your one had 64bit firmware? So I'm curious about that one. Thanks

09:19 <PabloPL> hexagonwin: I have Samsung S7 (8890), S6 Edge (7420) and Samsung A3 2016 (7578/7580). I got minimal kernel (with uart) boot on all of them

09:20 <hexagonwin> Ah, thanks! I think those devices are all 64bit, but still I'd try that u-boot patch.

09:21 <PabloPL> hexagonwin: S6 has clocks driver and UFS so right now i did put arch linux arm instead of android files and i'm booting it from UFS (this device don't have sdcard). Other has sdcard so it should be easy to boot it from sdcard

09:22 <hexagonwin> PabloPL That's nice. Btw, do you still have that patch edited that worked for you? If it's available I'd like to check it and see some things.. Thanks.

09:22 <PabloPL> hexagonwin: Just take that patch, adapt to Your device, flash in palce of normal boot.img (replace zImage with uboot), attach uart cable and check

09:22 <hexagonwin> Alright

09:25 <PabloPL> hexagonwin: If it won't work, just flash previous working kernel from recovery. Just check that serial port is correct one (the one used on Your device)

09:26 <hexagonwin> Alright! I'll have to first order the UART cable though :D so I'll probably try that in some months and report back..

09:27 <PabloPL> hexagonwin: Here is a info how to make one https://redmine.replicant.us/projects/replicant/wiki/SamsungSerial

09:28 <PabloPL> hexagonwin: Resistor value could be different - here they used 150k

09:28 <hexagonwin> Thanks, yesterday on here people told me a working how-to, I'll check this and that and buy the correct parts.
