We purchased an STR710-EVAL board and loaded into it the uCLinux, downloadable from the ST page.

As the linux boots, the ports 2.12, 2.13 and 2.14 begin to act as a counter and are counting from 0 to 7. These ports are associated to 3 leds, so I see the 3 leds blinking and counting.

We will build our own board with an STR710 core and uCLinux and we do need these ports. Is there any way to disable this counting?

Dear avelez,

You may change the led blinking example by modifying the arch.c file under ''linux-2.4.x/arch/armnommu/mach-STR710/arch.c '' directory.

Hi coucou,

Thanks for your reply. However, in that file only that content is shown:

--------

#include linux/tty.h

#include linux/delay.h

#include linux/pm.h

#include linux/init.h

#include asm/elf.h

#include asm/setup.h

#include asm/mach-types.h

#include asm/mach/arch

extern void genarch_init_irq(void);

MACHINE_START(STR710, ''STR710'')

MANTAINER(''ST MMCC'')

BOOT_PARAMS(0x00000100)

INITIRQ(genarch_init_irq)

MACHINE_END

----

I cannot see where should I modify the file :(

Yes, not the arch.c but the time.c and time.h instead. Hope it helps;

linux-2.4.x/arch/armnommu/mach-STR710/time.c

linux-2.4.x/include/asm-armnommu/arch-STR710/time.h
