i adder printk(...) before all function in kernel init funktion /init/main.c

log show last message before called fundtion local_irq_enable().

If delete my debug printk-s kernel stop after first console output "Calibrating delay loop... "

I do not MIPS arch interput specific ..... Can be MIPS need init internel timer and link overflow flag to interput ??

All handlers are not correctly setup, so you should include this patch in your tree:

I show this rtunk left 10 day....

and patch src 2.6.33 from dir root/trunk/target/linux/ar7/patches-2.6.32

to day i see :

florian: [ar7] add missing patch to arch/mips/kernel/traps.c to allow ar7 to setup … :confused:

------------------
for 2.6.33 need this modify ?? or not ?

#define CAC_ADDR(addr) ((addr) - UNCAC_BASE + PAGE_OFFSET -
PHYS_OFFSET)
---------

----------------
my console not work correctly - baudrate no standart ?! :( i change port type

---- i change port type in ar7platform.c to:

uart_port[0].type = PORT_16550A
to
uart_port[0].type = PORT_AR7

boot process ttyS0 detected as AR7.

Console baudrate not work correct again ....&-(

Ok, then why do not you simply use OpenWrt trunk?

If I could slip in with some shameless self advertising:

Same(ish) chipset, the 'Creating Firmwares' section should interest you and get you started on your buildroot journey.
