- Subject: [ECOS] i386 problem
Hi,
I tried till long ago running an eCos application on the PC target again.
Everything was working fine, but the application won't run :-(.
- Redboot is starting from floppy.
- gdb connects via net and via serial line.
- The application is builded for startup type RAM
$ ecosconfig new pc
$ ecosconfig tree
$ make
$ cd ex
$ i386-elf-gcc -c -o hello.o -g -Wall -I../install/include
-ffunction-sections -fdata-sections hello.c
$ i386-elf-gcc -nostartfiles -L../install/lib -Wl,--gc-sections -o hello
hello.o -Ttarget.ld -nostdlib
- loading the application works
target remote 192.168.1.155:9000
load
b main
c
-->
nothing is happen!
I have set a breakpoint at "hal_platform_init".
I can step till:
// ISR table setup: plant the default ISR in all interrupt handlers
// and the default interrupt VSR in the equivalent VSR table slots.
for (vector = CYGNUM_HAL_ISR_MIN; vector <= CYGNUM_HAL_ISR_MAX; vector++)
{
cyg_uint32 index;
HAL_TRANSLATE_VECTOR( vector, index );
here >> hal_interrupt_handlers[index] = (CYG_ADDRESS) HAL_DEFAULT_ISR;
HAL_VSR_SET( vector, &__default_interrupt_vsr, NULL );
}
but after vector is 70, the application stops at this line.
(the same over serial line)
Does anybody know what's going wrong?
Roland
