[ECOS] Redboot EB40a problems with flash programming

[Øyvind Harboe]

I've compiled a Redboot ROM image from the CVS sources
(fresh today). Redboot comes up as expected, passes a 
smoketest, but I seem to be unable to program the
flash using Redboot commands.


Any help would be greatly appreciated!



Here is what I did and what I saw:

- I have installed ecos using the instructions here:
http://sources.redhat.com/ecos/getstart.html

- I downloaded the latest from CVS and pointed ECOS_REPOSITORY
to the right spot

mkdir ecoscvs
cd ecoscvs
cvs -z3 -d :pserver:anoncvs@sources.redhat.com:/cvs/ecos co -P ecos 
export ECOS_REOPSITORY=/home/xxx/ecoscvs/ecos/packages


- Then I built Redboot

ecosconfig new eb40a
ecosconfig import
$ECOS_REPOSITORY/hal/eb40a/current/misc/redboot_ROM.ecm
ecosconfig tree
make

- In my early efforts to get Redboot installed, I accidentally wiped
Angel. We now have a Wiggler and a flash programming software that
we used to write the elf image into flash. (One of the hardware guys
I work with helped me there, so I don't have any details.)

- Redboot now runs fine(BTW, shouldn't the copyright be for 2003 
as well?):

- However, when I try to erase flash, things start to go wrong. My
*guess* is that Redboot crashed after it wrote 
"... Erase from 0x01010000-0x01020000: " to the serial port(I had
expected to see it return to the prompt).

RedBoot> fis erase -f 0x1010000 -l 0x10000

- Just for kicks, I tried to write a bit to flash(there is nothing
in particular in RAM, just testing), and I got:

RedBoot> fis write -f 0x1010000 -l 0x10000 -b 0x10000
