[Arm-netbook] Booting from SD card with switch on so-dimm in other direction ...

[Adam Gill]

Hi Jon, Luke .....

So far I have been unsuccessful with Luke's method ....

I will solder wires out each side of R46 ..which can then be shorted 
from outside the netbook when re-assembled ....

i believe you have  directly copied the entire NAND flash 2gb DIRECTLY 
onto the 2gb SD card ....

Could you upload exactly what you have put on the sd card? .... and how 
do i format the sd card? is it a straight copy and paste?

I will try both methods once i got the open of the shorted wires sorted 
out ?

Much appreciated ----

Adam
