just curious about what u wana do? test nand?
I'm also interested in the low level bootstrap procedure
so I pull the serial.c code from u-boot, but don't test it through
here is the patch~
before doing, must correct following error
since i don't how to fix it
(either replace get_PLLCLK function? or find a proper compile method?...)
~/src/speed.c:72: undefined reference to `__aeabi_uidiv'
~/src/speed.c:75: undefined reference to `__aeabi_uidiv'
hope helps
i change code
from:
if (pllreg == MPLL) {
return ( 2 * m * (CONFIG_SYS_CLK_FREQ / (p << s)) );
}
else
return ( m * (CONFIG_SYS_CLK_FREQ / (p << s) ) );
to:
if (pllreg == MPLL) {
return ( 2 * m * (CONFIG_SYS_CLK_FREQ >> ((p << s) >> 1)) );
}
else
return ( m * (CONFIG_SYS_CLK_FREQ >> ((p << s) >> 1)) );
then there are no error,
i don't know how to receive the serial output,
how to config my OS to receive the serial output?

S3C24X0_UART: include/s3c24x0.h
gd: funny one it seems type declared gd_t in
include/asm-arm/global_data.h and instantiation as #define using
arch-dependent register for speed.
get_PCLK: cpu/arm920t/s3c24x0/speed.c
to grep around I use like
~ grep get_PCLK * -R <--------------------------------this is more usefull :-)
