LS1043 RCW CRC is different from my calculation

[thehk]

Hello everybody, 

i am using LS1043ardb demo board, in PBL i tried to calculate and verify CRC at the end of the PBI END command. However it is different from what i calculated. I used more than one tool to calculate it so i don't think that it is a calculation mistake. The procedure that i follow, i collect all the memory region from beginning of the RCW data (0x6000_0000) to end of the END command which is located in PBI section. (except CRC i took all of them). But CRC is different where is my mistake?

Thank you for your interesting.

Try to use generate correct binaries with command below with Layerscape Linux Distribution POC User Guide, Rev. L5.15.71-2.2.0 5.2.3.1 How to compile PBL binary from RCW source file

1. $ git clone https://github.com/nxp-qoriq/rcw
2. $ cd rcw
3. $ git checkout -b LSDK-21.08 LSDK-21.08
4.  $ cd ls1043x
5.  If required, make changes to the rcw files.
