Hi, 

This is a question related to memory testing from within Uboot:


On a CPU (ppc476) there is 2 GB RAM which is tested in Uboot (the
operating system uses this memory). On the same CPU there is an
additional 256 MB memory chip which is used only by the IP-stack and not
the operating system. 

The question is, should this 256 MB memory be
tested from Uboot or should the IP-stack test this memory? 

What is the
advantage/disadvantages? 

Brs, 

Markus
