lte modem: missing antenna is not handled correctly
Sh-Anand opened this issue · 5 comments
When booted without an antenna, mbimcli does not connect to network even if the antenna is attached during runtime.
mbimcli instead errors:
Error: Device not registered after 101 tries
and then exits immediately.
Instead of exiting after a set number of tries mbimcli should retry forever with a backoff strategy.
As @Sh-Anand is currently working on his master thesis, I have taken over this Issue from him.
When I did want to test his changes, using the mbimcli run script I discovered, that this no longer works after the update to Genode 23.02. Therefore I created a separate commit that fixes this run script.
As I do not have the hardware for most of the platforms, I hope, this doesn't break anything. I was able to build it for all platforms up to where it tries to launch it. Except for RPI where I got the following error:

This could be due to my personal setup, as I normally do not build for any arm_v7a platform.
When doing further tests, we discovered, that after a signal loss (simulated by removing the antenna) the connection isn't re established. I created a separate commit that fixes this.
Except for RPI where I got the following error:

This could be due to my personal setup, as I normally do not build for any
arm_v7aplatform.
The script fails as rpi is an arm_v6 platform. Mind the missing library mk files, which can be found in the /lib/mk/spec/arm_v6/bootstrap-hw-rpi.mk subdirectory that is not visible in an arm_v7a build.
@chelmuth when I try to build base-hw for rpi (arm_v6) with the following branches
- genode: 23.02 (57fcc7a25f)
- genode-rpi: master (fe52ae28c3)
I get, beside others, the following error:
/data/genode/depot/genodelabs/src/base-hw-rpi/2023-04-17T1042/src/core/spec/arm/bcm2835_pic.cc:18:17: error: ‘Core’ is not a namespace-name
18 | using namespace Core;
| ^~~~
If I remember correctly the namespace Core was introduced in 23.02. Is there a known good combination of genode/genode-imx repositories, that I can use to build? Or are you fine if I do not investigate further?
I guess something got tangled up here.
- genode-rpi and genode-imx cannot be used in combination, most basically because rpi is arm_v6 and imx is arm_v8a.
- The
Corenamespace was introduced after release 23.02. - The available sync points between all genode repositories are the release tags.
So, please checkout tag 23.02 in both - genode and genode-rpi.
