Hi teacher,
When using TMS320F28023PTT,Some chips cannot start normally,replace a normal chip can solve the problem. This never happens when using automotive grade devices, TMS320F28023-Q1.
The fault phenomenon is that DLP does not run, DMD optical machine is not lit, but the computer end DLPC120 control program2.0.0.0 can connect TMS320F28023PTT through piccolo.
When the fault occurs, manually reset TMS320F28023PTT can be restored to normal, and the DMD optical machine is normal.
I need to confirm if there is a difference in the functional design between non-automotive components and automotive components. How can I avoid this problem?
