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
cdl_option CYGSEM_REDBOOT_FLASH_CONFIG_READONLY_FALLBACK {user_value 1};
Yes, I believe it could be a flash config problem. I have tried it but
with no success. I am still having the same behavior. The flash was
written (I'm sure because i can dump and see the ip address
server/mask/gateway) but seems that Redboot don't take this
configuration from flash at boot up.
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) ?
I also change it. Should I see the differences at fis list command? I
choose -4 as example and the Redboot config remains at 0x407FF000. It
should be at 0x407FA000. Did i understand the cdl_option right?
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.
Any help is welcome. No excuses, only thanks.
Regards,
Sergei
