Thanks for the log, i made a new build that hopefully fix the music crash issue: PRIME #2
I also made some slight changes to the heart rate sensor, please check if it’s working correctly, thanks.

The HRM is not working - the testing app says “test failed”. I’m pretty sure it was working with your first kernel. I also had a crash. Same situation but it took longer to crash than before. Here’s the log.

Thanks again for the logfile, it is unfortunately still the same problem.
Seems to be caused by the ‘fpsgo’ driver and a missing proprietary kernel module (which isn’t included).
It’s intended to boost gaming performance, but i don’t think this has a lot of use for our smartwatches, so i turned it off.

Anyway, here is a new build that should fix this issue: PRIME_#3

The crashing bug does seem to be fixed, and HR is working again. I tested every feature* (though not always extensively) and everything seems to be working correctly.

*Except phone features; I don’t have a SIM card in my Prime.

Here is a build for the Kospet Hope.

(Please note that i don’t own this device, some drivers like the display are untested).

Edit:
I updated the kernel images on the first post and added support for the Rollme S08.

I also found that the HRS3300 heartrate sensor in the Rollme supports blood pressure.
However this is currently not supported on the Android interface and can only be accessed via ADB:

echo 1 > /sys/devices/virtual/sensor/m_hrs_misc/blood_pressure
cat /sys/devices/virtual/sensor/m_hrs_misc/blood_pressure

Maybe someone has an idea how this can be made accessible to a (customized) Android app.

Here is a build for the Kronosblade Genesis.
(please note that the display and touchscreen drivers are untested)

Here is another test in which the CPU voltage was significantly reduced (from 1001MHz/1135mV to 910MHz/1000mV).
This is less intended for power saving, but more for reducing the heat output/overheating, which can be a common issue.

Edit2:
(the undervolting is already included in the images linked in the original post)

Edit:
Test with PCMark for Android shows:

Undervolt:

  • Points: 2387
  • CPU max. 60°C

Default:

  • Points: 2122
  • CPU max. 73°C

Nice. Would be interesting to get this for the genesis…:+1:

25

Did the Genesis test build worked?
I unfortunately don’t own this device, so i was hoping someone could test it and report back if the display and touchscreen was working correctly.

26

I haven’t test it yet. But I hope I will find some time this weekend. Is it voltage reduced, too?

I updated the link on the Genesis post to include the undervolting as well.

  • added lcm panel workaround

Can you please re-upload the kospet prime undervolt file and how can I install it? :slightly_smiling_face:

32

The undervolting was integrated in the new images that are linked on the original post, a quick tutorial how to flash these can be found here.
