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 […]
Yearly Archives: 2010
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
I fiddled with the u-boot env variables tonight to try and resolve the S-Video problem. One trick from the BeagleBoard mailing list said to set omapfb.mode=tv:ntsc and omapdss.def_disp=tv. I tried this but found that if I tried to run the boot manually to pick up these changes to the bootargs […]
BeagleBox: which u-boot am I fiddling with?
All the parts arrived by last Tuesday and I was able to boot the board using the validation images. I explored the u-boot environment and dug around the root file system to see what the BeagleBoard folks had put together. I booted the board using the serial console and connected […]
BeagleBox: reality sets in – boot issues
Most of the ordered parts have arrive, including the BeagleBoard. Man, is that a tiny board for so much capability! I can’t wait to bring it up. Still waiting on the USB hub and 1G SD card. I had to move a 25-in-1 USB-based card reader from my main development […]
BeagleBox: parts arriving
Taking a break from nerdom for a moment… I just posted pics from my garden this year. Despite warm temperatures not arriving till June, the garden flourished with a hot, dry ending that went all the way up to this week (second week of October). So the coleus and veggies […]
2010 Garden wrap up
2 I ported over Angstrom’s recipe for the SGX libraries into the BeagleBox build this week. It requires downloading the SGX SDK and unpacking it manually before you do the build. Angstrom will unpack it for you. And at the moment I’m not positive the layout I’ve created is completely correct […]
BeagleBox: SGX libs build, parts ordered, speeding up boot times
There were some minor changes required to Robert’s patches to get them to build the SGX drivers as kernel modules. One of the patches set drivers/staging/omap3_sgx/Kconfig to use “boo” instead of “tristate” which prevented the SGX build as modules because the Kconfig also required the build only as module (with […]
BeagleBox: SGX driver integration completed
I’m back from vacation and have been working on integrating Robert Nelson’s SGX patchset into the BeagleBox build. These patches implement the SGX kernel drivers for the BeagleBoard found in the OMAP35x_Graphics_SDK package for Linux. This allows building the SGX kernel modules with the rest of the kernel build instead […]
BeagleBox: SGX integration progress
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 […]
