iMXRT1024 DCP CRC-32 parameter settings

JasonGT93 — Mon, 13 Jun 2022 11:01:18 GMT

Hello,

I'm using the i.MX RT1024 evaluation board and trying to use the CRC32 to verify some data.

I used the dcp example without problem but when I tried to use the verify with an old data the result is not as expected cause of the settings.

The CRC32 included in the example use the parameters showns below:

width=32 poly=0x04c11db7 init=0xffffffff refin=false refout=false xorout=0x00000000

I know that these parameters are for CRC-32/MPEG-2 but my parameters are not exactly the same that these.

Is it possible to change these parameters?

Hi @JasonGT93

I hope that you are doing great!

After checking , I am able to confirm that the RT1020 DCP do not have a provision to change CRC-32 parameters. So you can only compute for CRC32-MPEG-2.

I am sorry for the inconvenience.

Let me know if there is anything else to discuss.

All the best,

Diego
