I installed Angstrom on my tosa and it seemed to work fine. However, none of the ipks I downloaded unstable/armv5te/base/ works for me. I used package manager and it just popped up an error message saying:
An error occured.
Please consult the message log for hints what went wrong.
I have no clue what went wrong and where to check message log.
In the system info -> log display -> System Log, I got:
Can't find circular buffer, is syslog running?
Can't find circular buffer, is syslog running?
Not sure if it's the same with Angstrom, but as far back as OZ, the package manager had problems. I'd recommend trying to install via command line using ipkg.
Example:
ipkg -d install
<location> might be something like sd, cf, flash, whatever. <package> is exactly that...if you've got an ipk downloaded, you can use that name.
You'll get a better idea what's going on if you do installs that way. If the install works via command line, but not via the package installer, then the bug might be with the installer itself. Check to see if there's a bug in the bugtracker.
