[ECOS] Re: E7T ROM Module Startup issue..

["Ali Sina" <replay688@hotmail.com>]

Hello again,

after some more work on this I find the following:

- the rommodule is showing up in the list as expected at 01820000

- when calling "plugin" with the module name I get a "Bad checksum f62b5bab" 
error. So it looks like the checksum is not computed correctly.

- setting the PC to 01820000 and then calling "go" produces the expected 
"hello rom" print message. So something must be working ;-)

- computing the checksum outside the makefile works fine - nothing 
suspicious there.

- replacing CHECKSUM inside the module with a number and repeating the 
procedure does not change anything. even the same bad checksum message 
appears.


Please, does anyone have a hint as to what is happening and what could be 
going wrong?

Many thanks in advance,

AS

Hello,

I am having trouble with an E7T ROM module.

1. I can build an E7T ROM Module according to the instructions in the list 
archives (i.e. Redboot ROM make file)
2. Writing module to Flash works fine - the BSL sees the module.
3. Module does not boot (upon reboot board goes to Angel)

Can anyone give a hint as to what the possible causes may be?

This topic has been discussed from various angles a while ago (see pointers 
below)
however I have not been able to find an answer.
The problem is also described here:
http://ecos.sourceware.org/ml/ecos-discuss/2002-11/msg00253.html

..but was not able to find an answer on the list. I am pretty sure that it 
must have been solved somehow.

Any help would be much appreciated, as this is becoming critical..

Thank you,

AS
