Hdparm has the following to report on my beagleboard:

/dev/mmcblk0:
 Timing buffered disk reads:   44 MB in  3.05 seconds =  14.44 MB/sec
/dev/mtdblock3:
 Timing buffered disk reads:    4 MB in  0.96 seconds =   4.18 MB/sec

The SD card is a Sandisk ultraII SDHC 4GB card (€20 including extra usb2 reader).

It seems I'll be sticking with root-on-sd for now :)

With some help of the MythTV people I managed to get it to build in OE and installed it on my beagleboard. Playback is slow because the ARM optimizations in FFmpeg don't get enabled, but that's fixable.

LugRadio Live 2008 is taking place this weekend and I'll be manning the TI booth together with Måns Rullgård of ffmpeg fame. We'll be showing off some demos on the Beagle Board like HD resolution MPEG4 playback, 3D demos and desktop like software (e17, abiword, etc).

The Neuros people will have a table next to us showing of their OSD2 HD platform.

The following articles don't mention the Ångström Distribution specifically, but they are using it on their Gumstix boards:

The most important drivers for the beagleboard (USB host, USB client, MMC and DVI output) are all upstream now in the linux-omap tree:

If you are in a hurry and want to insert a 3.5mm jack into the socket, take a bit of care. The jack I used had a long base and thick pull-protection, so it acted as a giant lever and pulled the ground pad right of the PCB :(
Luckily it was the ground pad, so I could connect it to the other sockets ground pad without much problems.

This is the 5th time this week I had to solder stuff (back) onto dev boards, but for once it was my own fault :)

A 4x crop of a picture of tulips. The Adox CHS 25 ISO has way more resolution than the lens of the yashica can deliver, but it has a really nasty curl, which leads to newton rings :(

The beagleboard is able to use usb high-speed (480Mbit/s) on its client port. Iperf says the following:

[  4]  0.0- 5.0 sec  43.7 MBytes  8.74 MBytes/sec

While that's certainly not the advertised 480Mbit/s, but more like 70Mbit/s, it sure is nice :)
