[ECOS] RedBoot FLASH config suggestion

[ECOS] RedBoot FLASH config suggestion

[Trenton D. Adams]

I get the error below every time I switch from a RAM version to a ROM
version or vice versa.  This only happens when "fconfig" has been run on
the other version (RAM|ROM).  So, I assume that the checksum is based on
whether a RAM/ROM version is running?  If so, what's the purpose of
this?  How do you get it so that the RAM version will use the same
config as the ROM version?

FLASH configuration checksum error or invalid key

Different source base used to build the two?

Nope, not possible.  I have the ECOS_REPOSITORY variable set.

The most probable case is that I've fixed bugs in the 'fconfig' layout
recently and that your ROM vs RAM versions are of different vintages.

Vintages?  I created both of them today using the eCosRepository that I
downloaded Monday or Tuesday if that's what you mean!

In that case, the more likely thing is that the recent changes introduced
differences somehow :-| - they did affect this area.

OTOH, looking at the code, it's difficult to see how it would differ.
There's no differences in your CDL to account for it perhaps, like 
CYGNUM_REDBOOT_FLASH_CONFIG_SIZE or CYGNUM_REDBOOT_FLASH_CONFIG_BLOCK?

Trenton, if you want to debug this, look at load_flash_config() in
redboot's flash.c. In the middle there's a call to crc32. At that point,
you could do a diag_printf of flash_start, flash_end, sizef(struct
_config),sizeof(config->cksum), config->key1 and config->key2. And then
build your RAM and ROM RedBoots from that. Tell us what you see.

[Sebastien ANDRE]

Hello, so i port redboot for a personnal board, and for this board the ram
begin to 0x10 000 000 adress
so all sections of the binary start after 0x10 000 000 except 3 sections

   o shstrtab
   o symtab
   o strtab

so i don't find anithing for move these.
What can i must do ?

thanks in advance.

best regards,

Sebastien.

You probably need to add expression matches for those sections in the
sh.ld script.   If you do sh-elf-ld --version you should be able to
see where those sections are usually located - add them in the same
place in the eCos linker script.
