  • Grant set to Porting Replicant to Android 9 (NLnet Foundation)
Actions #2

Updated by Denis 'GNUtoo' Carikli almost 2 years ago

So far:
  • heimdall flash --BOOT recovery.img --RECOVERY recovery.img doesn't work, even with the recovery being out/target/product/i9300 and being just built with make recoveryimage
  • reboot to recovery in various ways doesn't work (that's probably to implement somewhere)
  • But, but... The power + volume up + menu button when the device is off can boot that recovery

Caveats:
  • It has the LineageOS logo instead of the Replicant one
  • It prints this message:
    E: Failed to clear BCB message: failed to find /misc partition
    .
  • The blinking '_' cursor isn't disabled. If it uses the framebuffer, an ioctl is probably need to be issued to disable that (FBIO*?)

The colors are also wrong, but that should be fixed once we stop hardcoding that, and choose colorspace with the first client using the framebuffer / DRM interface.

We also need to find out how it works under Replicant 10: The partition size for the recovery is 8M and the recovery being generated is about 12M. Yet I had the recovery working and did adb sideload.

So we need to look if it's supposed to work like in AOSP or not and what exactly is flashed in the RECOVERY partition and when it is flashed.

I have:

$ heimdall flash --BOOT recovery.img --RECOVERY recovery.img 
Heimdall v1.4.2

It seems that I really have a 8M partition:

i9300:/ # ls -la /dev/block/platform/soc/12550000.mmc/by-name/RECOVERY

 179       12   12091392 mmcblk2p12

So RECOVERY is mmcblk2p6 which is about 8192KiB.

I sideloaded Replicant 10, then It hanged next boot with:

11-22 08:46:33.065  1284  1284 I bootstat: Canonical boot reason: reboot,ota

adb reboot normal fixed it.

Though I wonder if reboot,ota needs to be cleared somehow or where it is written.

Actions #10

  • Device Galaxy S 3 (I9300), Galaxy S 3 4G (I9305) added
  • Device deleted (Unknown)
  • Type of work Build system integration added

The recovery now works fine, and even there isn't big Replicant logos or text, Replicant is still mentioned anyway as:

Android Recovery
Samsung/replicant_i9300/i9300
11/RP1A.201105.002/replicant09011614
userdebug/test-keys

TODO:
  • We needd to produce zip "otapackage" files.
  • We still have to fix the following error:
    E: Failed to clear BCB message: failed to find /misc partition
    .
  • We didn't test install / upgrades or talking to the recovery from Replicant like we do with our experimental test libraries that can install Replicant 6 automatically.
  • We still need to remove the blinking cursor, but we'll do that once we have a boot animation during the standard Replicant boot, otherwise users have 0 clue the device is on and booting.
