TMDSCNCD263P: ECP: Error while connecting AM263P Control card on board debugger

Hi Team,

Greetings for the Day.

While debugging the code in OSPI boot mode, the target suddenly started throwing an error. Previously, the same target configuration (for OSPI boot mode) was working fine, but now it fails unexpectedly. I am using the onboard Micro-USB debugger.

I tried resetting the board and performing a power cycle, but it didn’t help.

Then I changed the boot mode to Development Boot mode and used the target configuration created for Dev Boot mode — in this case everything works fine.

What could be the issue, and do you have any suggestions to resolve it?

Below is the error screen shot

here is the console output

"Cortex_R5_0: Error connecting to the target: (Error -1170 @ 0x0) Unable to access the DAP. Reset the device, and retry the operation. If error persists, confirm configuration, power-cycle the board, and/or try more reliable JTAG settings (e.g. lower TCLK). (Emulation package 20.0.0.3178) "
