Part Number: TMS320F28335
Hi，
TMS320F28335 experiences chip non-stop reset upon startup. Strangely, reset is an input pin, how could the DSP keep pulling down this signal on its own? We have confirmed that this pull-down burr was caused by the DSP itself, not by external factors.
Restarting the fault does not eliminate it.
It is easier to reproduce a 5-second interval between power on and off, but longer intervals are less likely to reproduce.
Monitor the crystal oscillator. The crystal oscillator is starting to vibrate.
The timing should meet the requirements, but there is indeed a slight issue with the power waveform. The power chip uses TI chips, as shown in the following figure.
Please help analyze the reason. Thanks!
