s32k344 some memory denied access

huangjia — Wed, 17 Nov 2021 08:00:37 GMT

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?

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!

Jim,

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.

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