s32k344 some memory denied access

[huangjia]

Hi dears, i'm debugging s32k344 via jlink. I generated a project to toggle a led pin, and it can work fine. But i can not read the pin register via memory. How to set memory access range?

Hello, I want to ask whether you use j-link V10 or V11?

[huangjia]

no，I switched to pemicro

[dashe]

I saw that you said you used j-link first. I want to ask which model you used to use j-link

Hi@huangjia

I can accsee the address as you did,for example:0x40290000,

       I am currently using PE(I don't have a segger jink) ,so i think this may be caused by J-LINK ,may be you can try with onboard PE to trobleshoot this problem.

BR!

Hi@huangjia

      okay,welcome to discuss with you. 

      Are you use S32K3X4EVB or self-design board? S32K3X4EVB have an on-board debugger(can easily connect to PC by usb-wire) 

BR!

     Jim，

That is my self-design board. It is hard to apply a demo board now.
