Coreelec version 9.2.5 works perfectly, both from the microsd card as well as when running with emmc. Unfortunately, booting from emmc memory takes approx. 38 seconds, while normal boot from SD card takes approx. 20 seconds.

I am attaching the logs below:

1. Run from a microSD card

You won’t get any help for starting from emmc cause installtointernal will not be supported here.

3

That’s the “half” truth. It’s ceemmc used, not installtointernal. But correct the device isn’t official supported and tested by CoreELEC.

I looked into the dmesg and it’s not the eMMC:

[    5.866761@3] [0] release decoder
[   12.473281@0] meson6-dwmac ff3f0000.ethernet eth0: fail to init PTP.

Here you loose for whatever reason 7 seconds.

Please boot from eMMC. After booting inset uSD or USB stick. Run ceemmc and make a copy of the internal install to the external boot media. When done boot from the external media and make a dmesg|paste again please.

4

Can I do this on the nightly version? I installed it during testing and it stays that way.

5

Sure, it the same “delay” happen it does not matter.
Nightly is good.

Please also dump you Android dtb:

dd if=/dev/dtb | gzip > /storage/downloads/dtb.img.gz
6

I’ll have to restore Android. I’ll take care of it tomorrow.

7

You don’t need to restore it to dump /dev/dtb, it’s still available after ceemmc install.

8

Ok. I have.

Boot from Coreelec splash screen to Kodi ~ 23s

I checked you dmesg and it looks like a linear error in the booting time. So it looks like the eMMC speed is lower then your uSD.

You can confirm this by trying to write/read a test file on /storage:

CoreELEC:~ # echo 3 > /proc/sys/vm/drop_caches
CoreELEC:~ # dd if=/dev/zero of=test.speed bs=1M count=1024
1024+0 records in
1024+0 records out
1073741824 bytes (1.0GB) copied, 13.235369 seconds, 77.4MB/s

1073741824 bytes (1.0GB) copied, 12.030407 seconds, 85.1MB/s

Boot from eMMC and perform this 5 commands. Then boot from uSD/USB and do the test again.

Hm…

I would expect the other way :slight_smile:
Then I don’t know the reason why booting from eMMC is slower then from uSD. The transfer speed is better but boot slower!?

12

Well, that’s what surprises me too …
I checked this before, before starting the thread, but just forgot to include it in the logs.

Well. Let it be. I practically do not run the box anyway, it is always on. But I thought that I could improve and it would be better for others.

Maybe analyzing startup gives you a hint, see:

But … after a dozen or so reinstallations to eMMC it is a bit better - the boot takes about 25-30 seconds, not 40 seconds.

but it’s still 30 sec from coreelec splash to kodi…

16

Then it’s likely some HW init time which delays availability (not startup) of kodi.
But this is a question to the experts here…
