sd card

We’ve been thinking about getting into 3D printing here at the Hammel household. I’m looking at building small enclosures for the various embedded boards I work on. My wife is looking at creating components for the designs she works on for Vindicated Vinyl, her small business. After doing a bit […]

Getting started with the Robo3D printer and OctoPrint

I don’t enter many contests. I see little value in getting something for free. It’s far more interesting to earn them. But every now and then something catches my eye that seems worth the minor effort of a big reward. So a while back, perhaps back in September or so, […]

Halloween haul from Arrow

This past weekend I made the 0.4.0 release of BeagleBox. This is a major milestone for the project because it establishes the baselines for two of the core software componets, the bootloader and the kernel. I made a public release on SourceForge and updated the source and build pages on […]

BeagleBox: V0.4.0 released, wiki updated

Mon December 06, 2010 in BeagleBox / Hardware / Linux / Software Development / X11 tagged angstrom / BeagleBox / bootloader / BUI / dvi / dvi output / S-Video / sd card / sourceforge / u boot

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 ...

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

Mon November 08, 2010 in BeagleBox / Hardware / Linux / Software Development tagged beagleboard / BeagleBox / boot messages / bootloader / BUI / cvs versions / INITRAMFS / initrd / inittab / kernel configuration / pivot / ramdisk / sd card / serial port

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

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?

Tue October 19, 2010 in BeagleBox / Hardware / Linux tagged angstrom / beagleboard / BeagleBox / NTSC / omapfb / S-Video / sd card (updated 4929 days ago)

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 […]
