Is there any limitation that prevents the usage of 2 GB LAW on P1024 ?

Enabling a 2 GB LAW (PCI target) on a P1024rdb resets/hangs the board. I checked and there are no LAW/ATMU conflicts. Using two adjacent 1 GB LAWs for the same memory window works.

See below technical support comment:

A 2GB LAW will behave the same way as two 1GB LAWs only when base addresses of the 2GB LAW and the first 1GB LAW are aligned to the 2GB boundary.

I somehow missed that.

Thanks,
