Hi All, 

Additional inputs 

 Customer is asking if there is a way their firmware can tell if the CPU is AM3352 or AM554D80 or Z100? Like a register to read from?

• Please refer to the below register 

  Data sheet reference:

  www.ti.com/.../am3352.pdf

  3 Device Comparison

  Table 3-1 lists the features supported across different AM335x devices

  DEV_FEATURE register value(5)

  TRM reference

  https://www.ti.com/lit/ug/spruh73q/spruh73q.pdf

  Table 9-26. dev_feature

  Register Field Descriptions Bit Field Type Reset Description 31-0 dev_feature_bits R 0h Device-dependent, See Device Feature Comparison table in device data manual.

  FYI, the below thread could be reference. 

  (+) [Answered] Predefined Macro for AM335x - Processors forum - Processors - TI E2E support forums

  https://e2e.ti.com/support/processors-group/processors/f/processors-forum/442260/answered-predefined-macro-for-am335x/1586536?tisearch=e2e-sitesearch&keymatch=am335x%252520device_id#1586536

  Please refer below summary of inputs i received from the expert and this is in line with the above inputs i provided.

  The  device_id  register will be the same for each device of the same silicon revision.  You will not be able to determine a specific GPN using this register, just the device revision

   The DEV_FEATURE register is the correct register for GPN identification The Device Feature Comparison table in the datasheet has a register value associated with each GPN.

  In addition, the efuse_sma register contains details on the package type and max frequency.
