[U-Boot-Users] u-boot and Linux into an ace file

[Abdelmajid Bouajila]

is it possible to put u-boot with Linux image in an ace file?

Hello,

I am working on an ML300 board. I build my HW platform and I generate my ace
file using the HW and U-boot like this:

make an ACE file out of bitstream and U-Boot:
   $ xmd genace.tcl -jprog -board ml300 -hw  \
     implementation/download.bit -elf u-boot -ace top.ace



is it possible to put u-boot with the Linux in an ace file?

Thanks

Abdelmajid

Hi Abdelmajid,

I'm not sure that I understand why you want to do this. Making an ACE 
file out of U-Boot helps you in the development process of your Linux 
kernel/application as it allows you to download the Linux kernel and the 
RAM disk through the network, thus allowing to change the Linux kernel 
withouth having to rebuild the ACE file (containing U-Boot). If you were 
to include the Linux kernel with U-Boot you would have to rebuild the 
ACE file whenever you change the Linux kernel.

If you are trying to boot Linux from an ACE file there is an easier way. 
Build your Linux kernel with "make bzImage" then build an ACE file from 
the bitstream and the Linux kernel:

$ xmd genace.tcl -jprog -board ml300 -hw  \
     implementation/download.bit -elf zImage.embedded -ace top.ace


You can have U-Boot and Linux in two seperate ACE files and chosing one 
or the other with the dial on the board or through the 
touchscreen/bootloader that ships with the board.
