Hi Michael.
I don't have any 0Xda (confirmed) partition(s) on the micro-SD device at all,
so accordingly the device should not boot. I have only one partition 0x83
(Linux). Am I correct in interpreting your comments above that any partition
other than 0xda will cause the booting process to NOT boot from that device. Or
did you mean that if the device has a 0xda partition it will not try to boot of
the device? The second option makes more sense in a way.
Could you kindly verify your understanding as I have to find a way of using the
micro-SD card for application data.
OK, I could use the card for booting the kernel but as far as I understand from
the documentation I forced in having fixed partition sizes for booting, hence
any large flash device becomes useless for any more than 512KB. Is this also
correct?
Is there a way to "fool" the system into allowing the remainder of disk space
in another partition to be used for applications data?
If your comment meant to say a partition formatted as 0xda, then would it
suffice to create a boot partition formatted as 0xda, and place additional
partitions using 0x83 etc...?
Thanks for you inputs.
Best regards.
