[MinnowBoard] firmware update requires new SD card install?

[Douglas Kryder]

OK, Brian. Thank for the information. It took me 30 min to do afresh
install of Linux mint 17.1, but it is good info to be aware of
in the  future. I appreciate the details of you post. Thanks

If you can boot to the shell, then you should be able to launch the Linux
loader from there. Each Linux installed will have a sub-directory under
\EFI containing its loader. Example from my system:



FS0:\> map -r

hello,

i flashed a firmware update to a minnowboard turbot today going from 0.78
to 0.92 and after the flash the linux install on a SD card would not boot.
i did not spend a bunch of time researching if this is to be expected so if
it is i apologize for the post. but, would this be a normal thing? i was
thinking maybe some kind of file allocation table structure might have
change between the firmwares. thanks
