I use the same ubl for both dm368 and dm365 ,and i want to config different arm clock automatically.

if there any difference between the DM365 register values and DM368's ,

or can i distinguish DM365 from DM368 through register values?

You can use the DEVICE_ID register for this purpose.

I can't find this register,could you tell me the register address?

I wonder if you read and/or searched the datasheet and user's manuals....

For the DM365, the datasheet is here: http://www.ti.com/lit/ds/symlink/tms320dm365.pdf

On Page 50 is a listing in Table 3-1 of the System Module Registers (DEVICE_ID is one of them). The PDF text also includes the link to the User's Guide (also here: http://www.ti.com/litv/pdf/sprufg5a)

In that document, Page 138 (Table 89) describes the register contents of the DEVICE_ID register.

The same information is available in the DM368 datasheet, but I'll leave it up to you to find it.

Dear Sir,

We meet the same scenario.

The DEVICE_ID looks the same either from ARM Subsystem user's guide or direct print of such register from DM365/DM368 device.

I use regrw in linux to read register 0x01c40028 (DEVICE_ID), both DM365/DM368 got 0x8b83e02f.

Does there any solution to automatically identify DM365/DM368 from chip registers?
