Hi Eason,
I faced same problem while porting ecos on my target board. I found that Printf was using some different serial port (which is not on my target board) for sending character. When i debugged i found that code is contineously waitting for serial line clear signal of that serial port.
Thanks and regards,

Hi everbody,
I'm a newbie for redboot. I wanna port the redboot into a
lubbock-like(pxa255) board, however I got some problems. My redboot
hanged at cyg_start(void) in main.c . As below is the hang point..
cyg_start(void) {
....
for (init_entry = __RedBoot_INIT_TAB__; init_entry !=
&__RedBoot_INIT_TAB_END__; init_entry++) {
printf("\nCalling __RedBoot_INIT_TAB__ %p/%p\n", init_entry,
init_entry->fun);
(*init_entry->fun)();
printf("init start %p \n\n",__RedBoot_INIT_TAB__);
printf("init end %p \n\n",&__RedBoot_INIT_TAB_END__);
printf("KK value %d \n\n",kk);
kk=kk+1; ===> hang point
}
....
}
boot output :
Calling __RedBoot_INIT_TAB__ 0xa000a6fc/0x0000c588
init start 0xa000a6fc
init end 0xa000a700
KK. ====> hang...no output kk value
So, what's such problem?? thanks in advance.
