we would need your help to look into the following case where
The problem description is the following; signal XCLKOUT is missing at any time and they believe that uC has no clock.
They do not have idea what the problem is. It looks that uC is broken.
They produced 4 prototypes, and all are not working where power supplies start up and values are correct.
They tried use external 1.9V oscillator without any progress. They also tried to supply other uC 28335 on the external board from 3.3V and 1.9V. Startup is OK, and board works fine.
They shared rtg of BGA and picture of system start up with 1,9V, 3,3V and /XRS measured time diagram. (Provided those separately)
