Thanks Jon Szymaniak,
I was not aware that the bootrom signature support has been added to the 
current version of u-boot. I was able to built the 
u-boot-with-spl-dtb.sfp target and the single concatenated u-boot file 
worked on Cyclone 5 board right away.

[yocto] Altera Cyclone V u-boot-spl with meta-altera

2016-01-22 Thread Usman, Fahad 
Hi, I am using meta-altera layer (https://github.com/kraj/meta-altera) 
to build u-boot for Altera Cyclone V socfpga board. Building the 
u-boot-socfpga_2013.01.01 recipe does generate the u-boot-spl binary, 
but it cannot be directly used on the board as it has to be signed using 
Altera's tool "mkpimage" that comes with Altera's toolset (SoC EDS 
). 



Is there a way to produce a signed u-boot-spl image during the build, 
that can be used directly on the target without using the EDS?


Thanks,
Fahad.

If you upgrade to the U-Boot 2016.01 (or maybe even earlier?), mkimage
actually supports adding the Bootrom signature to the SPL for you.  The
current makefile is kind enough to concatenate the U-Boot SPL and its DTS
for you, and then run mkpimage to create an 'spl/u-boot-spl-dts.sfp' file
[1].

If that doesn't work for you, you might find [2] to be useful.  The bootrom
"signature" is simple enough to implement in a do_compile_append() or
custom task.

Re: [yocto] Altera Cyclone V u-boot-spl with meta-altera

2016-01-22 Thread Randle, William C 
I’m not aware of a tool outside of Altera’s EDS mkpimage. What I ended up doing 
was installing a subset of the EDS tools (mkpimage and the jre directory), then 
tweaked the u-boot spl/Makefile to automatically invoke mkpimage to create the 
preloader. I also tweaked the meta-altera u-boot-socfpga.inc do_deploy() rules 
to copy the newly built preloader-mkpimage-* files to the deploy directory.

I’d be happy to send those to you, if you’re interested. Likewise, if you find 
a third party tool to add the preloader image header, let me know.
