Reading APPROTECTSTATUS register with J-Link commander

[raccoon]

Hello to all embedded Jedi Knights!

I was wondering, how could I read the CTRL-AP's APPROTECTSTATUS register (of an nrf52832) using the J-Link commander.

I know that I must invoke writeDP to select the CTRL-AP and then use readAP. I am just missing the arguments!

Hi,

You can read it like this:

SWDSelect                  //Selects SWD Interface
SWDWriteDP 1 0x50000000    //Enable power
SWDWriteDP 2 0x01000000   //Select CTRL-AP Bank 0
SWDReadAP 3 
SWDReadAP 3

Thank you very much!
