TMS320DM368: Die ID register for DM368

Part Number: TMS320DM368

Hi,

We got the gel file that reads the Die ID register  for DM368 from local CQE.

I readed Die ID register using Jtag and ccs but  Die ID is read as ARM9: GEL Output: Die id Values DIEID3= 0x00000000, DIEID2= 0x00000000, DIEID1= 0x00000000, DIEID0= 0x00000000.

The gel file is a simple code that reads the Die ID after writing special values to unlock registers for unlock.

What else do you need to do ?

Please advise me to solve the problem.

Thanks!

JP

    Hello,

    Not a DM368 expert, but just came across your post. The gel print out is just one way to read register values. You should be able to also read the DIE ID registers from the Memory view and/or Registers View of CCS. For example in the memory view got to the DIE ID register address, and you should be able to read a true value. If you are still seeing 0's something is not configured correctly and you are not able to access registers on the chip.

    thanks

    Hi Alex

    I look at the DIE ID register address from the Memory browser of CCS but DIE ID register is 0x00000000.
    I also tried to write a special value directly into unlock register of the memory browser to unlock it.
    but DIE ID register is 0x00000000 and unlock register also is 0x00000000.

    The strange thing is to write a specific value in the unlock register, but the unlock register  in the memory browser is still 0.

    Let me know if this is true.
     
    I got the gel file that reads the Die ID register for DM368 from local CQE.
    The content of the Gel file is to write a specific value into the unlock register and then read the Die ID register.
    Can I upload the gel file I have received from local CQE?

    Thanks!

    JP,

    Thanks for the follow-up. Yes, didn't think of that, looks like the lock register needs to be programmed with a specific key then. Please follow up with the local CQE/FAE if there are any NDA restrictions on that gel file distribution. If not we will be more than happy if you upload it here so others can see it and use it to read the DIE ID too!

    thanks, appreciate it!
