No I did not it, but with the FP emulation on, the Linux runs...
Many thanks for your help.

Sure. But where can I find the standard rules ?
Are the rules dependent on each demo board like 8560_ads ?
Do the custom boots respect some rules ?

Right. I let the kernel configure the memory TLBs but I use
a call to io_block_mapping to open the IO space
io_block_mapping(0xf0000000, 0xf0000000, 0x10000000, _PAGE_IO);

Thanks again
