I am now try my attempt to port a Lantiq device however I have some questions.
1) mtd partitions
The original firmware only comes with 2 partition uboot and rootfs.
Do I have to the original partition configuration or can I add my own partitions like uboot _env and rootfs_data?
2) LED GPIOs
How do I actually find out which LED is linked to which output?
Help please. Thank You

You can use as many partition as you wish. You don't need to create rootfs_data manually, it will be automatically created.
2) LED GPIOs
How do I actually find out which LED is linked to which output?
Either by looking into the manufacturer's GPL sources, or by trial and error:
First
echo $GPIO > /sys/class/gpio/exportWhen checking for led:
echo out > /sys/class/gpio$GPIO/direction
echo 0 > /sys/class/gpio$GPIO/value
echo 1 > /sys/class/gpio$GPIO/valueIf it was connected to a led a led should have turned off or on when writing 1.
When checking for button gpios:
echo in > /sys/class/gpio$GPIO/direction
# don't press the button
cat /sys/class/gpio$GPIO/value
# now press the button
cat /sys/class/gpio$GPIO/valueIf it was connected to a button, then the value should change between 0 and 1 when (de)pressing it.
Repeat as necessary.
Thanks

You need to provide a mach file for "GR7000"
Hi I just copied wholesale in the folder /trunk/target/linux/lantiq/files/arch/mips/lantiq/xway/
mach-wbmr.c to mach-gr7000 and renamed everything inside from wbmr to gr7000.
I am quite sure it is the wrong but I don't have any better idea...
Things I added/modified
/trunk/target/linux/lantiq/files/arch/mips/lantiq/xway/mach-gr7000.c
/trunk/target/linux/lantiq/image/Makefile
/trunk/target/linux/lantiq/ar9/profiles/007-aztech.mk
/trunk/target/linux/lantiq/ar9/config-default
Can someone please enlighten me?
I am still stuck.
In your source LANTIQ_MACH_GR7000 exists in mach-gr7000.c?
MIPS_MACHINE(LANTIQ_MACH_GR7000,
"GR7000",
"GR7000",
gr7000_init);Do your define it in machtypes.h?
I think I know why, the files are not in the source yet, it is in the patches...didn't think of looking at the patches.
TS, any update on this?
The discussion might have continued from here.
