Re: [ECOS] redboot hang problem!!

Yes, I had traced the init_entry->fun() and found it's acctually call
to load_flash_config() in flash.c (RedBoot_init(load_flash_config,
RedBoot_INIT_FIRST)). However, after finish with that, next step can't
be performed contiguously.

If I comment current printf, it will hang at previous printf. It seems
fine, but ignore some errors at previous procedure so that hang at
here. How can I do to catch those undectetable errors?
Thanks in advance!!
