Can you bring me some light ? I'm currently digging a whole while been in the fog without any shovel ... :unsure:

Now that I checked changes again, it just about power key connected to PMU, so probably that's not it.

 

So, does reset with PineH64 U-Boot work on OPi or not? If not, then it has to be some peripheral settings...

Not on fresh boot, as well as original OPi U-Boot, but both work well if the BSP U-Boot handler is still in memory.

 

This is why I've said "Back to SquareOne" when I've investigated the reset_cpu() code from arch/arm/mach-sunxi/board.c

... and I still don't catch why PineH64 U-Boot works fine on PineH64 boards ...

pity, oh well let's hope the best of it

honestly had the feeling it was so close to a satisfactory solution, but alas ...

thanks for all your efforts though it is appreciated. cheers

I've tried looking into it. Mainline u-boot has a reset command, wich triggers a watchdog based reboot, and it just locks up the machine, when the watchdog timeout expires. The same thing simply happens in kernel. Kernel tells ATF to reset, ATF does the same thing as u-boot (watchdog based reset), and the SoC locks up.

 

Presumably, there's some other setup needed on H6 to make the SoC reset correctly. Maybe CPU resets into an incorrect PC adadress. Who knows? I didn't find anything obvious by looking at the reset code in the BSP u-boot/kernel. It will be something less obvious.

What is even less obvious is that using the same 5.0.y kernel branch and same v2019.01 u-boot, the PineH64 reboot properly while other H6s are freezing.

I've compared DTs and defconfigs between PineH64 and other H6s and didn't found any obvious differences... :(

 

EDIT : I've almost forgot : I've compared also schematics, just in case it been an hardware issue, but didn't find any differences there too ...

Maybe setting the register that controls where the CPU starts executing after reset via RVBARADDR register, before triggering the watchdog may help.

Since I wasn't aware of those RVBARADDR registers, I've look at the doc and figure out that those have locations at 0x09010040, 0x09010048, 0x09010050 and 0x09010058.

I've used "./devmem2 0x09010040 l" which displayed 0x0000000000104108, and then "./devmem2 0x0000000000104108 l" which displayed 0xF2A618A0D2810600.

This is the same on all boards, PineH64, OPi3, OPiOnePlus and OPiLite2 ...

I'm trying to recreate the bootproblem of the PineH64, but no luck. It misbehaves because it behaves.

I don't know why, it did it yesterday a few times. The crash moment was right before Starting kernel. Then there's only 1 cursor on the screen, and it stayed there multiple minutes. I'll keep trying.
The law of TTL? It only does it when you're not watching...

Hhmmm doesn't fix the issue :'(
 
[    3.497925] sunxi-wdt 30090a0.watchdog: Watchdog enabled (timeout=16 sec, nowayout=0)
still stuck
Maybe nowayout param should be set to 1? I remember that nowayout=0 on H3 just disables watchdog hardware reset as described here: https://www.kernel.org/doc/Documentation/watchdog/watchdog-api.txt

There is some discussion on forum here with H3 CPU, worth to be read.

BTW, make sure that you have "verbosity=7" as well as "console=serial" to get as much as details possible in case you reproduce it.

How to do that? My google doesn't seem to know, or I ask it the wrong question. I see something of -v, but where to stick that -v...
I also tried using putty before, but I can't copy text in Armbian. Any way to do that?

Press both mouse buttons at  same time to paste to putty terminal if that is what you mean.

Normally yes, but those things don't work. Normally you just select what you want to copy and it's in the clipboard. But I ain't having that on Armbian...

It is in /boot/armbianEnv.txt ...

Thank you. I again learned something new.
It isn't doing it anymore. I've been rebooting the whole day. Not once. Yesterday is was about 25% of the times. I don't know how it's possible. I did upgrade my eMMC image today, but my sd-card image is still not upgraded. So that's not it.
I never hated it so much that a device isn't crashing.
From now on I'll keep a 2nd sbc running for serial.

"IIRC there are 3 watchdogs on the H6. One is the trusted watchdog, which should be reserved for underlying firmware. The other two are the normal and R-block watchdog. Although they look the same, the "normal" one can't reset the system. :( That one is actually the one ATF currently uses. So reboot doesn't work on the H6.

ChenYu" - https://lkml.org/lkml/2019/4/5/425

 

If it's true it's strange that the reboot works on PineH64...
