Hi Bjarke,
Hmm .... i implemented it, what ever you are looking. foloow the below
Step :
=={ I am assuming your recovery image is already implemented and ready
to boot }===
Step : 1 : Open a simple file in android data or Cache partitions.
from Java file ex: RecoverySystem.java, in which very first call come
for recovery. and write any string in that File ex: "xyz" . Do this
stuff from java code.
Step 2: Now Go to Uboot main file and when there a read happen for
boot cmd, read the this file( i hope you can implement this by reading
your file system from uboot code :) Option one read the file , second
read the number of character in the file and then compare in uboot
code and if match with your defind set go ahead for boot recovery
image.). i hope you know , at this point , you will be changing your
boot cmd ---> ponting on recovery Image.
Step 3 : dis works , very few change is required for the above
solution. hope you will enjoy the above step : )
Step 4; --> think about the above opened file, what you can do for
next step.
