[okl4-developer] Booting N810

[Ashish Bijlani]

Hi Josh,

I cannot flash uboot onto the device coz it doesn't have any serial
port open. nokia advices not to play with the serial port. the flasher
and nokia loader are indeed not open source. however, there is an
equivalent open source user level flasher
(http://www.nopcode.org/0xFFFF/) available that has support for n810.
even if i choose to to add support for flashing uboot in this open
source flasher, it won't work coz this flasher is just a client side
utility to talk to the NOLO, which is the 'server-side' part of the
flasher from Nokia. It is composed of two pieces which are not open
source.

is there any other way? can't okl4 produce zImage of the final elf and
use gz/inflate/deflate compression/decompression method (like linux)
to decompress the final image.boot/image.elf on the fly? is it hard to
do this? pls lemme know. thanks.
