Be warned, there have been some reports of the journal of ext3 wearing out its part of the SD card. Actually, there haven't been any such report. There have only been posts such as yours trying to scare people away. If you're a masochist, go for ext2 without hesitation. Otherwise follow the usual recommendation, regardless of whether the disk is made of rotating platters or flash memory. Stefan PS: Yes, there can be cases where ext3 wears out a flash disk a bit faster than ext2. None of those cases should occur on a smartphone. ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Can I just ext3 the SD card ? I'm not very fond of FAT... Also, as of: http://wiki.openmoko.org/wiki/Booting_from_SD It says: WARNING: Booting from SDHC may cause problems at this time (see below). Should I even try to boot from the SD card? Are there outstanding issues that I should know of? How small of a card is too small? Will 2GB be usable/enough or should I plan on something bigger/smaller? Finally, should I Om 2009 or SHR ? Thanks! ET PS: This flashing thing ain't easy... For dumb people like me anyway... :( ___ Openmoko community mailing list community@lists.openmoko.org http://lists.openmoko.org/mailman/listinfo/community

Also, as of: http://wiki.openmoko.org/wiki/Booting_from_SD It says: WARNING: Booting from SDHC may cause problems at this time (see below). Works fine for me. This may refer to the Neo1973, or to old bootloader versions. Should I even try to boot from the SD card? Are there outstanding issues that I should know of? Some cards don't work reliably at the default clock rate, so you may need a kernel command line switch adding to change it. You may need to change the uboot parameters for kernels 2MB, or use Qi which handles large kernels and boots faster. How small of a card is too small? Will 2GB be usable/enough or should I plan on something bigger/smaller? Depends on what you're doing with it. 512MB is fine for most distros, but 2GB is probably more appropriate for debian or gentoo. You may want more space if you plan to use it for audio. video or maps. Finally, should I Om 2009 or SHR ? Thanks! ET PS: This flashing thing ain't easy...
