OS image on SATA?
« on: August 05, 2013, 01:10:01 pm »
Hi,  I ordered but still waiting for my CB2 to arrive through Sweden Post and in the mean time going through the forum articles  to obtain some knowledge.

I have a question about the boot up sequence from MMC (or SD card)

In Raspberry PI,  if I go to fat partition of the SD card image and modify "cmdline.txt"  so that instead of /dev/mmcblk0, I specify /dev/sdx to point to HDD that is connected through USB port,  only partition that RasPi requires on SD card is the fat partition(in another word /boot folder contents), the rest of Raspbian image can reside on HDD and the device continue to boot/initialize from HDD.  I am runnning RasPi off of old 256MB SD card and 2.5 inch SATA drive attached through USB port with this arrangement.   read/write seems snappier with HDD compared to SD card (even with class 10)

I wonder if the similar setup is possible with CB2 using SATA i/f on CB2 but then not sure when SATA driver is loaded during the boot.

Yes it is similar. You can edit uEnv.txt or build boot.scr with proper configuration. More....
