1036342 - [Flame][v2.0] No Wifi: missing driver & files.

Status: RESOLVED FIXED

(Firefox OS Graveyard :: Wifi, defect)

Description

[Nicolas B. Pierron [:nbp | PTO until 11/11]]

When building from sources:

  BRANCH=v2.0 ./config.sh flame
  ./build.sh
  ./flash.sh

The wifi cannot be enabled, simply because the Wifi driver and its files are missing from the system partition.

The problem seems to be related to Bug 1009396, which first landed for disabling the fact that we pull files from the backup.

https://github.com/mozilla-b2g/device-flame/commits/v2.0
https://github.com/mozilla-b2g/device-flame/commits/master

I suggest we cherry-pick the fact that we pull files from sources[1] and update the manifest[2] on v2.0.  The other option is to revert Bug 1009396 changes from v2.0 [3].

Let's get bug 1009396 fully uplifted. It doesn't make sense to have bug 1009396 half landed in 2.0.

NI: how exactly does this impact an end user, if its build only and helpful for testers/dev's can you seek approval here ?

hoping to get his in 2.0 by uplift request, clearing the nom

I requested blocking on bug 1009396 - I didn't see any appropriate approval flag for b2g32

Per bug 1009396 comment 51, this should be fixed. Please make sure that you rebuild with uptodate sources.

Yes, the Wifi does not appear while in order to run benchmarks on a flame v2.0.
A new line should appear here, a few hours after fixing this issue: http://arewefastyet.com/?a=b&view=regress#machine=26

After some repository surgery from Alexandre, this issue is now fixed locally.

The problem being that if you already have a B2G tree which has been configured for the flame, then the extract-files script added a /vendor/t2m directory which is still tell the build system to use the driver which are coming from the backup of the flame instead of building the driver.

The driver is indeed present on the phone but it had a version mismatch between the driver and the kernel, which caused failures while loading the driver.

Work-around:
 - ./repo sync
 - remove B2G/vendor/t2m
 - remove out/target/product/flame/system/lib/modules/pronto/pronto_wlan.ko
 - ./build.sh && ./flash.sh

=> Works for me now.

I just set up the nightly of Firefox OS 2.0 and it works perfectly.

Thank you :)
