Having spend a day and some trying to boot qtmoko or shr trying different
combinations (bootloader+ distributions + partition scheme ) from two micro
sd card i own, without any success , and since the cards are accesible from
linux kernel i'd like to pledge for help in that issue. I admit i havent play
more with uboot enviroment and uboot prompt but i've tries the rootdelay
option.
Some questions:
1)For example why there is need each dist to have its customized bootloader
file? Doesnt that imply that there is no general bootloader working like in
desktop pcs?
2)Why generally speaking its so difficult to boot from a sdcard? Is the microsd
interface closed and thus a libre drivers has holes? Is it a card's fault ?
(in what way , shouldnt they comply with a standard? ). Is it glamo hardware
thing? Is the glamo mmc driver 's fault ? All the above in different
combinations?
Some reports (the kernel? or the bootloader? stops and i get messages like
below)

PS: my 2 cards are 8 GB microSDHC memory card Kingston (class 4 :
15MBit/s-2MB/s) and a 1GB from a nokia phone with no company logo. Also i've
asked a friend and i'll try with a sandisk 4GB.
Thanks!
