Bootloader for uClinux-MMU with EPCS

Thanks for the reply. Sorry, I wasn't clear...and I had a typo.

In our design, the boot copier needs to copy the image from the EPCS to external memory at physical address 0x20000000 (I incorrectly stated 0x02000000 before). Unfortunately, that address is only reachable through the TLB. This would mean that the boot copier needs to initialize the MMU. My plan is to modify Altera's default boot copier, but I'm looking for opinions first.

Thanks!
