Is it possible to release a more recent u-boot version that supports ext4 boot? It appears that the u-boot that udoo uses is from 2009 which only has ext2/3 and fat support. Ext4 without journaling should perform much, much faster than any of these file systems, and performance is especially important for people who will be using udoo as a microserver like i do. Of course releasing the source code would be awesome, but for the moment I'll be content with closed u-boot with ext4 support.
The UDOO team is already working on the uboot 2013, we are about to validate it. When ready we will release binaries and sources too!
That's incredible news! Looking forward to fiddling with the quad core cpu once I get my ext4 root boot up!
Hi, You can build an Sd card with 2 partitions! Kernel in first partition. Ext3 Filesystem in the second partition ext4 In this way you don't need an uboot supporting ext4 for kernel loading
Hello miousername, That's technically true, but hard to do right in reality. Let me explain: The reason to use ext4 over ext2/3 is performance. The performance of a SD card depends on a bunch of things, but one of the most important one is block alignment. Now we don't know about the page size/erase size of most SD cards, so we have to fiddle around and guess, and a lot of times we will get it wrong. Then with that knowledge you have to format the card with the correct parameters, which again is easy to mess up. The more partitions you have, the more probable you will mess it up. That's the reason I'd rather have one ext4 partition than a ext2 and a ext4 partition. Ain't gonna bother with multiple partitions again. And btw: how's the new u-boot going? I would also like to see f2fs support, so I can compare the performance between that and ext4. Looking forward to the new release
