Trying to come to grips with the myriad of source trees from which BeagleBoard related source can be pulled, I updated the BeagleBoard build system the other day to make it easier to pull from the various archives. Technically there are four ways to get source related to BeagleBoard: A […]
Software Development
After upgrading to Fedora 14 at work I did some builds against various kernels, u-boot, buildroot and toolchains we use. I ran into an interesting problem. make[2]: Entering directory `/home/mjhammel/src/cei/sysbuild/bld/buildroot-2010.05.xcc/output/toolchain/linux-2.6.32.14′ /home/mjhammel/src/cei/sysbuild/bld/buildroot-2010.05.xcc/output/toolchain/linux-2.6.32.14/arch/powerpc/Makefile:178: *** mixed implicit and normal rules. Stop. ?A bit of googling shows that make 3.82 changed in a way […]
make 3.82 vs the world
It’s a wonder what you can get done once the board actually boots up to a shell prompt. Tonight I completed setup of inittab and boot scripts – along with customization of the rootfs build – to force writes normally bound for the rootfs to end up on a tmpfs […]
BeagleBox: tmpfs for writes, for now, but new u-boot ...
I finally got a rootfs working with the kernel tonight. It’s a minimal rootfs built with buildroot and busybox but it boots up to a shell prompt and does just enough work to make sure ps displays the process list. Whoopeeeee!!! Now, don’t get crazy here. This is just booting […]
BeagleBox Milestone: the board boots with BeagleBox software!
This weekend I buckled down and merged the BeagleBoard validation images kernel configuration into my BeagleBox kernel configuration. When I booted the resulting kernel with the validation images ramdisk image it worked. Unfortunately, because there were a fair number of changes to merge in it isn’t clear exactly which ones […]
BeagleBox: kernel boots initrd, initramfs still doesn’t work
I couldn’t figure out why my initrd or rootfs wouldn’t work and had exhausted all obvious solutions. Jumping to Occam’s Razor, I decided the problem may be with the cross compiler toolchain. So I grabbed Free Electron’s (FE) embedded Linux training lab (which focuses on the BeagleBoard) and decided to […]
BeagleBox: small steps – better xcc, u-boot/kernel boot but ...
With a better understanding of what’s happening with the Beagle Board validation images I’ve started to redesign the boot process for BeagleBox. First, the SD card will be partitioned with two partitions. The first is the FAT32 partition to hold the kernel image, boot scripts and an initial ramdisk (initrd). […]
BeagleBox: understanding the boot process requirements
Last Friday I finished updating the kernel build for the BeagleBoard to support building a kernel suitable for use with the SGX drivers. The build depends on the kernel patches from the TI AM35xx/OMAP35xx PSP SDK. In order to make it easier to build BeagleBox I decided to extract just […]
BeagleBox: SGX kernel build ready
2 I’ve updated the Design page to reflect the knowledge I’ve acquired about the OMAP SGX and DSP. There’s still some work to be done in understanding exactly how Clutter fits into that picture but I’ll get there eventually. In the meantime I’ve completed stripping out the theme support from the […]
BeagleBox: Stripping themes, new bugdb project, updated Design
I’m working two main issues at the moment: stripping Matchbox to get a new BUI core and working on building and packaging the SGX SDK drivers. The former is going well. I’ve stripped session management and gconf already and checked those in. I’ve got themes stripped down so that the […]
BeagleBox: Adjusting the design, learning about SGX and DSP
I’m in the process of doing an analysis of the Matchbox code to determine what needs to change in it to create BUI. So far I’ve mapped out the basic code flow and identified the purposes of the files within the window manager, which is where I’m starting the analysis. […]
BeagleBox: kernel update, BUI initial release and analysis progress
I decided a fork of Matchbox made the most sense for the BeagleBox UI. There isn’t much activity in Matchbox and the developers are busy with other projects. Besides, Matchbox is for hand helds while BeagleBox is an STB. The fork is named BUI, for BeagleBox UI. Not too original, […]
