Part Number: TMS320F280049
we have two scenarios, one working as expected, DSP is resetting after receiving the ext reset, and faulty behavior when DSP is not resetting.
we have used the GPIO5, it is configured in BTLDR as output with level low, and in APP, we configured the GPIO5 to be high. and if the reset is done, the BTLDR will be executing, and we need to see the falling down.
Attached two captures with good and faulty behaviors.
* First test:
The ext reset was done (grey line), however the GPIO5 (bleu line) wasn't resetting.
This is the correct behavior that we see in around 90% of our samples:
* Second test:
After power on we have a timeout waiting for the reset test, we put GPIO5 to 1 if we detect the timeout.
in the capture below we don't see the GPIO high because we didn't reach the timeout.
This is the reset circuit that we have:
DO_RESET_DSP is a DO from our Supervisor microcontroller. we are monitoring the PIN XRSn that we have in our JTAG connector.
