Hello all,
Sorry, I know this has been discussed a lot before, but I'm missing some
answers.
We are developing a GTK+ application on this board. We were preparing the dev
SDCARD as follow:
fdisk, create 4 partitions, 2+3 as Non-FS
# dd if=sd-mbr.dd of=/dev/sda bs=440 count=1
# dd if=kernel-image-latest.dd of=/dev/sda2
# dd if=initrd-busybox-rootfs-latest.dd of=/dev/sda3
# mkfs -t ext3 /dev/sda4
# (mount, untar debian-etch-xorg-512mb-aug252008.tar.gz, unmount)
The device then booted on the SDcard on a etch/arm distribution and our
application ran EXTREMELY slow. So I got as a goal to gives it a speed boost,
and after searching a bit I learned about EABI/armel.
So I grabbed this distribution from TS ftp and extracted to partition4 instead
of etch: debian-lenny-eabi-armel-512mb-apr092009.tar.gz
Of course, simply doing this the device won't boot anymore.
Question #1: Does the kernel-image-latest.dd is compiled to support EABI or
only OABI?
Question #2: Does I need to update the initrd to be in EABI too or since the
EABI kernel also support OABI it's unneeded? Cause I can't find any EABI initrd
on the TS ftp.
Question #3: I communicated by email by a certain Martin guy who seemed to know
a lot about this. He recommended to use his cross-compiler instead of the one
on the TS website, because he patched GCC to use "armv4t, eabi and
maverik-crunch fix" which supposedly gives even more speed boost for floating
points. Is that a good choice? The link is:
http://freaknet.org/martin/crosstool/packages/arm-ep9312-linux-gnueabi-gcc-g++-4.1.1-glibc-2.4-crosstool_0.42-1_i686.tgz
Finally, on this mailing list I found this guide link:
http://ted.openavr.org/Lenny-on-ts7390/
It seems nice, but I wonder why he goes trough the trouble of debootstrapping
when TS offer a debian-eabi already packaged
(debian-lenny-eabi-armel-512mb-apr092009.tar.gz).
So, the most important question is, how do I get this thing to boot?!
Thanks
