Re: [microblaze-uclinux] Newbie question about external ram executability

Hi,
I suggest you to look at the application note XAPP482, especially at page 7-12. There is also a project example. 

Cheers,

Hi,


  I've created a flash programmer/ram test/xmodem download program in order
to download the uClinux kernel to the board when it is just being brought
up in production (sometime later this year?!!).

 I used mb-objcopy to create a binary image from a small test program.

  I downloaded the program into external static ram at 0x80000000 and
verified it was there.

  I created a small boot program to jump to that address, and used mdm
assembly language stepping to prove that the "brild r9, r15" code was about
to jump to 0x80000000 (in r15).
