Hello,

Please may you confirm the PLAFORM_SIGNATURE register in APP_RCM is unique to each device.

So I could use it to link test results to a specific IWRL6432 IC

Thanks for confirming - do you know if there are any registers that are unique to each device?

You can use the DieID, which can be called using the fe_fecssDieIdGet_rom(M_DFP_DEVICE_INDEX_0, &deviceDieId). You can find an example of this in the motion and presence demo in the SDK. Those registers aren't accessible directly via memory so you will have to use this API to get that information.

Sincerely,

Santosh
