TMS320F28377D: TMS320F28377D DCSM issue

Hi,

Can you unlock the device and then check the value of these locations in OTP (GRABSECTR/GRABRAMR/CRCLOCK/PSWDLOCK) CCS memory watch window and share the screenshot or the values from this memory watch window?

Hi Vivek

Thanks for you support.Pls tell me how to unlock?I make below test

I can download blinky_cpu01.out use uniflash tool,flash setting as below,so i think the chip cann't be lock,it is correct?

Hi Vivek

After unlock,screenshot or the values from this memory watch window as below,pls check it

Hi Vivek

I modify CSMunlock（）；,screenshot or the values from this memory watch window as below,pls check it

Hi,

I was asking for values in USER OTP locations and not memory map registers. Anyway looking at these values, it look like you have program these fields as part of your .out. Once these are programmed, you can not change then again (it's OTP - One Time Programmable).

From memory  browser,we can find address from 0x78000  to 0x78093 data is 0xffff , screenshot as below

I see the CPU state as running  when you are viewing these values. You need to halt CPU and then check the value.

Thanks for your support，I have resolve this problem,But I donn't known why CCS Flash seeting cann't take effect，I can set up DCSM correct via uniflash.

Good to know you were able to resolve the issue. What do you mean by CCS Flash setting can not take effect? Does that mean you can not program security setting via CCS Flash plug-in GUI ?

Vivek

Yes,it not take effect
