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 

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 

Some reports (the kernel? or the bootloader? stops and i get messages like 

qi booting shr ------------

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.
