Hello.
A previously successful project suddenly becomes undebugable.
what is the reason?

It comes with a debug screen and a connection test screen.

Best regards.

The screen is not attached, so resend it.

Hello,

Have you seen the troubleshooting guide? Please see:

https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html#c28x-the-debug-probe-reported-an-error

https://software-dl.ti.com/ccs/esd/documents/ccs_debugging_jtag_connectivity_issues.html#invalid-data-read-back

The latter error occurs when there is some low level hardware JTAG connectivity issue.

Based on your emulator pack version, it looks like you are using some old version of CCS. I would also suggest updating your CCS version to something more recent.

Thanks

Thank you.

It turns out that the CPU is corrupted.
