Looking for an example RCW that someone has used to successfully boot SecureBoot on a T1022. I have one that I think should be working (Modified memory map, scratch registers being set, etc) but when I change the SB_EN bit = 1 I hit a machine check.

T1022 is a proper subset of T1042. QorIQ SDK includes ready and verified secure boot RCWs  for T1042RDB and T1042RDB-PI. Unpack the package called 'rcw', inspect the source. Detailed instructions can be found here:

I'm not seeing a 'rcw' package anywhere in the SDK. Where can I download the package from?

You do not have to download anything in addition to the SDK source DVD image. rcw package is part of the SDK:

$ bitbake -s | grep rcw

rcw                                                   :git-r0                         

Install the SDK and follow instructions at the links I posted above to unpack the package and inspect it's source.


Have a great day,

So I got RCW's but didnt see any for the T1042, are they not part of the 2.0 SDK?

Is there a way to get the RCW's without downloading the full SDK? Or could someone Just post the contents of the RCW?
