After messing with eMMC partitions, PBP won't boot, even from SD card
#6
@imij,
If you have re-enabled the eMMC via the physical switch, (while still booted from  SD card), you can force the OS to recognize the eMMC again using;

Code:
echo fe330000.sdhci >/sys/bus/platform/drivers/sdhci-arasan/unbind
echo fe330000.sdhci >/sys/bus/platform/drivers/sdhci-arasan/bind

This is necessary if you missed the short window where it's booting the SD card, but the SD card OS has not come up completely. It's literally a few seconds, so pretty hard. Easier with the 2 commands above.

I use the following for my partition table so I KNOW where the 3 parts of the boot loader exist. Note that for some reason, "/boot" needs to be partition 1, so the partitions are out of order. But, hey it works for me.

Code:
Device            Start      End  Sectors  Size Type
/dev/mmcblk1p1    32768  1056767  1024000  500M Linux filesystem
/dev/mmcblk1p2       64    16383    16320    8M Linux reserved
/dev/mmcblk1p3    16384    24575     8192    4M Linux reserved
/dev/mmcblk1p4    24576    32767     8192    4M Linux reserved
/dev/mmcblk1p5  1056768 13639679 12582912    6G Linux swap
/dev/mmcblk1p6 13639680 61497310 47857631 22.8G Linux filesystem
