I just tested e-0.21-n-20240608-CUSTOM-espresso3g.zip,
I am sorry but after the Samsung_logo only a black screen is displayed, so i tempt a format /data → not better…
This device is reputed a nightmare to build, Only @Android-Andi have achieved it…
However @Mighty told me yesterday that there will be no problem to build /e/nougat from official LOS sources

hmm, I took the official LOS sources and applied the patches needed for hardware_ti_omap4 only.

maybe this is the issue or other patches needed too?

ok, last try. I applied now all patches I could find:

still a black screen after the Samsung Logo…
thank you for your time !

wich sources did you use ? those from @Android-Andi or those from @Mighty ?

The official LOS sources and patches for andi

Sorry, I am out of development for years now and by accident formatted the SSD with all sources synced.
Black screen could be everything… Selinux, wrong blob and kernel combination. Try to get a dmesg and see if you find something telling what’s going on and what not.

Best regards

Andi

Local manifest example, also on how to replace the CM omap4 repo:
https://github.com/andi34/local_manifests/tree/cm-14.1

Those branches uses a newer DDK! Changes in Frameworks also needed, see the patches here:
https://github.com/andi34/android_pull/tree/v1-nougat

My omap4 hardware repo already contains everything needed.

Hope this helps! Make sure to use the right branches!

Overclock kernel. Has own def config!

Hey andi, something offtopic but the patches in other branches link to ua gerrit which is down.
As far as I recall we just need the frameworks/ab patch for video decoding using Ducati right? Otherwise it should atleast just boot

@piero did you try these patches?

Posted sources + patches (patch files, can be applied easily) should be fine and is what I used in the past. If I remember right added the omap4 hardware patches there too, to apply onto the lineageos hardware repo.

If using my repo:

I used the official sources from lineage for the device and applied the patches from the repo as above.
I remember that 2 of the patches I could not apply from the vendor/cm branch…I need to lookup for the error messages again
Building however went fine, but apparently those 2 patches are needed.

@ronnz98 some patches are only needed for the newer DDK. That might explain the bootloop.
New DDK depends on the hardware/ti, frameworks/native, vendor/ti and kernel/ti/omap4 (hope I didn’t forgot one).

I will try with your repos

If it boots you might think about using the OC kernel. Tab 2 isn’t snappy :stuck_out_tongue_winking_eye:

Ketut Kumajaya on XDA developed / adjusted the OC Interface long time ago and was used by many users by his legend Blackhawk NEXT kernel.

ok, now I took sources from Android-Andi and build for latest nougat (0.21) without patches:

Testing e-0.21-n-20240613-UNOFFICIAL-espresso3g.zip :

  • it boots…

  • i see the e bouncing…

it is expected to be long…

  • first boot wizard… :+1:

the screen need to be in portrait to be abble to ignore the lack of SIM card.

  • BlissLauncher boots :+1:

BlissLauncher don’t allow Landscape mode, even if its locked screen allow it.

  • there is no browser, is it expected ?

Edit : it should be not the “final build”…

after some minutes, touch and screen were buggy, black screen, swipe to unlock screen don’t work,
now it’s a bit better.
also, even if GSM icone or wifi say it’s good, f-droid can’t download, don’t update repo,
bluetooth don’t work
reflash,
install kit stop to work when trying to install “Mull” from SDcard
MTP don’t work, adb don’t work…
i have seen a message tells system not responding when i wanted to reboot
now it is stuck on the reboot window… i needed to force shut down and reboot
factory-reset don’t help…

thanks for your effort
