Hello,

On UM10995 (04 April 2018), page 53 of 113.  Can anyone please provide details on how to acquire the CRC for the following instruction:

 

The procedure of setting the CRC result of application

SET_APP_CRC_CMD (0x3E)

 

I'm referring to the array C0, C1, C2, C3 described in the aforementioned manual.  

 

1. How can I acquire this 32bit value from the application bin file that will be used?

2. What CRC equation must be used for the referred array?

 

I've been searching for this information for months.  Am hoping somebody could provide details about this.

 

Many thanks in advance!

 

Best regards,

William Tañada
