I use the orginial firmawre R9 without modification (Legato 18.03).
When I build and flash legato 18.05.0 or 18.05.1 the mangOH red reboot after 5s and bootloot and finally rollback to legato 18.03.
Not issue with Legato 18.04.0 but another problem with the 18.04 : assetData setting command don’t work. In debug I have nothing in my setting handler. When I roll back to 18.03 It’s OK.
We lost time each time a new release is done. I would to use latest legato build only because this necessary to build mangOH red system.
We plant to use Sierra solution in the world for 10k systems but I’m worry now and tired to support all this bug. I know this team work fine but don’t forget that we have customer who have to use this solution and don’t care about sofware issue.
If the system don’t work they will see for another solution.
