Ah, I did pass your vis-a-vis dialog with Gary. I'm seeing now what is
your issue. That is a flash config issue, isn't that? I look at some
RedBoot options/semaphores and found this one


Perhaps, some fail(s) protected itself by such a way? But, you told that
fconfig copy in RAM is good. Did you tried to change the default flash
config block number (cdl_option CYGNUM_REDBOOT_FLASH_CONFIG_BLOCK) ?

Execuse me that my useless suggest about DEBUG* options. I would play
with a set of the CYG*REDBOOT*FLASH*CONFIG defaults at the end: editing
`ecos.ecc' and re-building RedBoot. But that can take your whole weekend.
