2022-12-10Remove demo sllin configurationScott Murray1-59/+0
Remove recipes providing sllin configuration for the full demo, as all LIN usage is being replaced with CAN. The recipes for the sllin driver and associated lin_config utility are kept for now in case there are external uses.

2022-07-06sllin: switch to updated upstreamScott Murray1-1/+1
Changes: - Switch the SRC_URI of the sllin driver recipe to point at the new revived upstream location, update to their latest commit to get newer kernel support, and drop all the now unnecessary local patches. - Added a patch to fix compilation against 5.4 kernels before 5.4.110. This will be worked with upstream as time permits. - Rename the sllin driver recipe with a _git suffix to match OE style expectations. - Added the sllin driver to packagegroup-agl-demo as was being done in previous releases. - Split the demo script + service unit and lin_config configuration out of the sllin driver recipe into a new sllin-demo recipe so that they're no longer conflated. This should make it easier for others to reuse the sllin driver recipe. - Update the SRC_URI and SRCREV of the lin_config recipe to also point at the new upstream location/version since it comes out of the same repository. - Add the new master mode "-m" flag to the lin_config command line in the start_lin_demo.sh script (now in sllin-demo). This turns out to be required for our demo usecase as upstream seem to have inadvertently changed the default behavior.

2020-08-19Add can-dev-mapping-helperjellyfish_9.99.3jellyfish/9.99.39.99.3Scott Murray1-1/+2
Changes: - Add a can-dev-mapping-helper.sh script and systemd unit to drive it, the script checks if the CAN devices specified in the low-can configuration file /etc/dev-mapping.conf exist, and if not brings up corresponding virtual CAN devices. - Add a systemd over-ride conf file for agl-service-can-low-level that makes can-dev-mapping-helper a dependency. This should ensure that the low-can binding always starts even if there are no physical CAN hardware devices. - Added a Before statement to sllin-demo.service to ensure that it will run before can-dev-mapping-helper and ensure that lin_config can create sllin0 correctly. - Removed the sllin-demo-virtual systemd unit, as it will no longer be required with can-dev-mapping-helper. - Updated the /var/run paths in sllin-demo.service and associated start_lin_demo.sh script to quiet systemd warnings about /var/run usage.

2019-12-29Add virtual sllin support and LIN bridging to CAN for demosScott Murray1-4/+8
To enable seeing the steering wheel LIN messages on the cluster board for the planned CES demo, a systemd unit that wraps the use of candump in bridging mode is added when the agl-cluster-support feature is enabled. To make sure that the sllin0 interface is always available for testing without the specific demo LIN hardware, a vcan interface is set up as sllin0 when the ttyUSB0 device representing the serial adapter for the LIN transceiver is not present. Since this virtual sllin0 interface is very useful for general testing of the steering wheel event support up through the low-can and signal-composer stack, it has not been hidden behind agl-cluster-demo-support.

2019-11-06Update LIN demo to use lin-configScott Murray1-2/+5
Changes include: - Add patch to fix lin-config recipe build QA error. - Tweak lin-config recipe to install lin_config as executable. - Rework sllin-demo systemd unit and start_lin_demo.sh script to use lin_config with an appropriate configuration file that enables polling of the steering wheel adapter instead of just using ldattach.
