| PinePhone won't boot |

Hello everyone
I got my "Manjaro Community Edition with Convergence Package" a couple of days ago and tried to set the phone up yesterday.
The first time I tried to boot it, I just removed the battery seal, connected it to USB power and gave it a go with no SIM and no SD inserted. A red LED in the upper left corner of the phone started to light up, but the screen did not do anything. After maybe 15 seconds the red LED went off. I retried several times to power on the phone, but it would just not boot.
I assumed that maybe there is no OS on the internal memory, so I went ahead, downloaded beta1-20201104 of Manjaro Phosh and burned it to the SD with dd.
I then inserted the SD into the PinePhone and tried to start it up several times. All I ever got was the red LED. After maybe 10 attempts to boot the PinePhone, the screen was finally lid and I saw the Manjaro logo alongside a loading animation for about a minute before the device has switched itself off again. I was unable to make it boot ever since. All I ever see is the red LED.
I tried to find my way around the wiki, but couldn't find a useful starting point for my case.
Should I try to have a look at the logs on the SD?
Many thanks for your help in advance.
PD: I am new to Linux.

Phosh is nice at first, but I'm not really happy with it:
* HDMI is not always recognized
* windows do not always fit on the screen. Often they are just too big. Mostly settings windows of other applicaions (which also appear as floating windows in other tiling window managers; can it be that hard to make all windows fullscreen by default?)
* some features expected for a phone are missing
Are there other mobile window managers, I can try on Manjaro?
I tried to run Plasma, but I think it was the desktop variant.
On most systems I use i3, but I think, there's nothing similar yet for mobile. Is it?

Dear pinebook pro users,
I have spent a certain amount of time reading about the pinebook pro cpu voltages (rk3399) in pine64 wiki overclocking and I have come up with two ideas:
1 - Improve battery by adding a slight undervolt:
The default cpu clocks and voltages for rk3399 big cores are the following (Extracted from https://github.com/torvalds/linux/blob/m...9-opp.dtsi):
Cpu clock - Cpu voltage
408Mhz - 800mV
600Mhz - 800mV
816Mhz - 825mV
1008MHz - 875mV
1200MHz - 950mV
1416MHz - 1025mV
1608Mhz - 1100mV
1800Mhz - 1200mV
As suggested by the wiki, more optimised voltages can be found in: https://github.com/torvalds/linux/blob/m...1-opp.dtsi which are the voltages used in some chromebooks with the rk3399:
Cpu clock - Cpu voltage
408Mhz - 800mV
600Mhz - 800mV
816Mhz - 825mV
1008MHz - 850mV
1200MHz - 900mV
1416MHz - 975mV
1608Mhz - 1050mV
1800Mhz - 1115mV
2016Mhz - 1250mV [last freq can be skipped as it requires a slight overclock]
1.1 - How to apply such improved voltages?
The default ones can be overrided in arch/arm64/boot/dts/rockchip/rk3399-pinebook-pro.dts . This has been already done by tsys in its kernel to overclock to 2000Mhz - 1300mV ( https://gitlab.manjaro.org/tsys/linux-pi...ok-pro.dts ):
Code: &cluster1_opp {
opp08 {
opp-hz = /bits/ 64 <2000000000>;
opp-microvolt = <1300000>;
};
};
So in our case we want to change it to the following:
Code: &cluster1_opp {
opp03 {
opp-hz = /bits/ 64 <1008000000>;
opp-microvolt = <850000>;
};
opp04 {
opp-hz = /bits/ 64 <1200000000>;
opp-microvolt = <900000>;
};
opp05 {
opp-hz = /bits/ 64 <1416000000>;
opp-microvolt = <975000>;
};
opp06 {
opp-hz = /bits/ 64 <1608000000>;
opp-microvolt = <1050000>;
};
opp07 {
opp-hz = /bits/ 64 <1800000000>;
opp-microvolt = <1150000>;
};
};
2 - Improve CPU performance with a small overclock:
The main concern with overclocking the CPU in this laptop is that when attached to the charger, the battery will discharge when it is under a big load. My guess is that with the overclock proposed in rk3399-op1-opp.dtsi , the discharging problem can be solved as we are not exceeding the "The highest safe voltage [...] for the big cores is 1.25V" (extracted from the overclocking wiki mentioned at the beginning of the post):
2016Mhz - 1250mV
2.1 - How to apply such overclock?
Following the same guide as for the improved voltages (Section 1.1), we need to add:
Code: opp08{
opp-hz = /bits/ 64 <2016000000>;
opp-microvolt = <1250000>;
};
As I don't own a pinebook pro, I can't test any of the proposed changes. Would anyone try them and report if they are stable?

Hello,
I have a postmarket phone that has run very well up until now. Today, I upgraded mobian, I turned off the phone, waited a few minites and restarted it but only the green light came on then nothing. I made a fresh re-install, upgraded the system, rebooted and I ended up exactly in the same situation like before - the green light comes on and the phone hangs.

eMMC Fails After Suspend |
|

Most of the time, after the device going to sleep and waking up, everything works fine. But on occasion, when the device wakes up, the eMMC does not, and disk requests hang. For example, if I had a terminal already open and type 'ls' in it, it hangs. As one might expect, the DE also starts falling apart rather quickly.
Does anyone know what the issue here is? Is my eMMC chip bad, do I need a new u-boot firmware, is it a kernel or userspace bug?

Started up my new PBP this morning, install goes well. A few minutes after initial boot, the screen freezes - I can use the mouse but nothing works. Tried letting it sit for 5 minutes or so, no dice. Had to shutdown. Have restarted 5 times now and the same issue issue persists. Can’t seem to do anything in settings or terminal before it freezes. Any advice??
Thanks for reading

Does anyone know where or how to catch signals from the power management module. DBUS? /proc? I am porting kalliope and I need to shut down whenever the phone sleeps or suspends or even blanks the screen.
Between ACPI, DPM, pm_utils and Crust I am not sure where to look. Or what to look for.
TIA
LF
