just to confirn, if you hexedit your lart blob you do not what are the
last 100 bytes or so?
I'm building with:
./configure \
--with-linux-prefix=/home/timr/work/vercel/linux \
--enable-maintainer-mode \
--enable-clock-scaling \
--enable-memtest \
--enable-debug \
--enable-lcd \
--enable-jffs2 \
--enable-md5 \
--with-board=idr \
--enable-all-features \
arm-linux
make
lcd and clock scale are not yet supported.
