For PN: TMS320F2812PGFA we have supplied to our customer and they got back to us asking for questions about unstable DSPs
Questions
- Found that some DSPs(I/O pins) were unstable in our system when the power supplied the system.
1) Please let us know unstable DSPs are normal or false
2) Please explain what might caused unstable DSPs.
As for your reference, please check below and screenshots I pasted.
SCI error
1. Test of Swapping the DSP → The test result was changed after changing Error DSP to normal DSP in Card System.
2. When initial Power(5V) supplied the card system, I found that some I/O pins were unstable in case of false DSPs.
