TMS320F28388D: Verify stable connection - controlCARD XDS100v2

Art Mecina

Hi Team,

Our customer is having similar issue.

They are developing an application with the TMS320F28388D controlCARD. They already created a composer GUI. Now there is one problem. Their applications will still run even if the XDS conenection is not stable or lost. Is there a register with a live status bit? Meaning a register on C2000uC which can be checked if his XDS connection via GUI composer is active or not? So in case of an error in the XDS connection they can "stop" the procedure.

The solution on removing the Gel file of the core is to remove the initialization phase right?

Thanks in advance.

Art,

Based on the description, I think you should be able to use TRSTn_pin_status bitfield available in RESC register.

Manoj

Thank you Manoj.

This pin indicates a reset which is caused after the reconnection with the USB. Is there also a bit that indicates that the connection is lost (and not restored?)

Thanks and regards,

Art,

This TRSTn_pin_status can be used to detected whether JTAG is connected (or) not. We don't have any other register (or) bitfield to detect JTAG status.

If TRSTn_pin_status = 0, JTAG is disconnected

If TRSTn_pin_status = 1, JTAG is connected

Regards,

Manoj
