hi all
I use uboot version u-boot-socfpga-socfpga_v2013.01.01
the kitboard is cylone v
static int display_banner(void)
{
(void) getc(); //this line is modify
printf("\n\n%s\n\n", version_string);
debug(“U-Boot code: %08lX -> %08lX BSS: -> %08lX\n”,
_TEXT_BASE,
_bss_start_ofs + _TEXT_BASE, _bss_end_ofs + _TEXT_BASE);
#ifdef CONFIG_MODEM_SUPPORT
debug(“Modem Support enabled\n”);
#endif
#ifdef CONFIG_USE_IRQ
debug(“IRQ Stack: %08lx\n”, IRQ_STACK_START);
debug(“FIQ Stack: %08lx\n”, FIQ_STACK_START);
#endif
return (0);
}
the problem is not add modify line uboot printf not display
only display mian.c fun abortboot 's (void) getc(); run after
only display bootdelay count
add modify line
i must hit the any key of the keyboard
can run next step
and the after ( display_banne) fun all printf can ok
i feel serial_init fun error or init isn’t finish
but i am not sure this
