Why need to import the redboot_R[AO]M.ecm file? I found that there are two files, so which file I need to import or import both of them?

If I want to port the reboot to the AT91EB40, do I need to write the ecm files [ram and rom] for AT91EB40?

If I select another template [not redboot], do I need to write the ecm files?

I don't know how to write the ecm file, where can I find some reference materials.

If I want to download a testing program to the target board via gdb stub [rom startup], do I need the flash programmming tool?

Thanks! :D

For RAM startup import _RAM.ecm, for ROM startup import _ROM.ecm. They
set some additional parameters not set by the template.

Yes - but as I said, have patience: there'll be released a RedBoot
port for AT91EB40 in a week or so.

No.

.ecm files are just configuration settings. They are created using the
ecosconfig export option (and similar, if existant, in the graphical
configuration tool).

Don't know if it's needed to put RedBoot in flash, or if there's
already a board monitor there. Wait for the RedBoot release - it'll
have documentation for getting started.

RedBoot on the EB40 uses one half of the on-board flash (Angel is left
in the other).  No flash software is required.  

After RedBoot is installed, you have a complete environment running
from flash (RedBoot) and the ability to download and run code (either
directly from RedBoot or using GDB).

This means that RedBoot crashed during it's initialization.  Obviously a lot got
running, hence GDB being able to run.

In order to help more, you'll have to tell us:
  What platform (architecture, board)?
  What tools did you use to build with?
  What extra options (if any) you selected?

RedBoot only uses the HAL diag I/O routines.

BTW - exclamatories(!) in the subject will often send your message directly
to the "round file", especially mine :-)

Hi

Here are some questions I want to ask:

1. I have selected the redboot template in the config. tool and then I select ROM startup, import all the necessary packages, without changing the redboot default setting, debug serial port and diagnostic serial port are same (0). After that, I generated the bin file and download to the target board and use the hyper terminal to connect the target board. I saw a string like this -> $T0540:fff05cd8;01:00004664;#92 and I can use the gdb to connect the target board and display the value of the registers. My problem is that I didn't see the "Redboot>" at the hyper terminal [com1 and com2], so what is the problem?

2. Which one is the redboot used to communicate with hyper terminal?
The device driver in packages\devs\serial or the function in hal_diag.c

[ECOS] RedBoot Problems!

[Chris C.]

Hi
 
Here are some questions I want to ask:
 
1. I have updated the latest version of repository and selected the redboot template (PID platform) to build the redboot but some errors occured. I haven''t change anything.
 
2. Can I just update some sources or packages from the anonymous CVS repository and use them with the other sources or packages [v1.3.1]?
 
3. I knew that redhat will  release a platform HAL for AT91EB40, shall I modifiy the sources in the redboot package so that it can port to the AT91EB40?
