TDA4VM: TDA4VM: how to get the soc_udi

hi TI，

Read the following information , I am very confused how to use the API TISCI_MSG_GET_SOC_UID to get the SOC UID?

looking forward to your answer, thanks

Secure Debug User Guide — TISCI User Guide

Retrieving the SOC UID via TISCI

The TISCI_MSG_GET_SOC_UID API can be used to retrieve the SOC UID to print for reference:

SOC_UID[0] = 0xB89194C8
SOC_UID[1] = 0xB30FADED
SOC_UID[2] = 0xEC01F2A5
SOC_UID[3] = 0x7BF1AF4C
SOC_UID[4] = 0x5AEDE0CD
SOC_UID[5] = 0x7DB145C8
SOC_UID[6] = 0x49074EA1
SOC_UID[7] = 0xCBD422DA

Please note that the data is formatted in little endian fashion and bytes inside individual words need to be reordered before populating the debugUID field in the certificate. Alternative is to cast the response payload to a byte array before printing to view the values in byte order.
