Hi
In the final SLM version , please provide an option to disable and enable JTAG in software (thru AT command or by some means)
As part of security, this is needed

Hi Sharath,
APPROTECT protects the physical debug interface. (see the doc.)
FOTA etc. is of course possible since that is not done over the debug port.

Hi Martin
For a JTAG APPROTECT locked field returned unit , if a developer wants to analyze how to unlock jtag and debug/analyze (without erasing FLASH)
Any provision to inlock jtag APPROTECT?

Sharath
Hi Sharath,
As mentioned earlier and referenced to the documentation:
Martin Lesund said:Martin Lesund said:Only way to recover from only APPROTECT enabled is an full erase of the FLASH.

Hi Sharath,
Regarding security, I strongly suggest against another solution than using APPROTECT, e.g. where you could "disable"/"enable" JTAG with an AT command.
If you really need access to the JTAG port for a device in the field, then you could just connect, erase the application and re-flash the same application then you can debug as much as you'd like.
I think that is the best current solution and also secure against any other people getting access to the application.
Please specify why you would like to access the JTAG port for a device out in the field.
Best regards,
Martin L.
Hi Martin,
The suggestion you gave is valid, but before re flashing the unit with debug code, if we want to read the logs from the faulty unit how we can get the logs.
Can we have AT Command to read RTT logs through serial interface.
or
Through serial AT command to enable disable RTT logs
