Re: In progress: IAP from external miniSD card and/or USB

2005-02-05 by acetoel

Great! It's a very nice idea... I'd love to see that code, and try to
port it to Atmel Dataflash... They are cheaper than a miniSD, a
2MBytes version is enought to archive several codes, and then select
which one you want to program, it's fast...
Congratulations... great project!

Move to quarantaine

This moves the raw source file on disk only. The archive index is not changed automatically, so you still need to run a manual refresh afterward.
