Re: [ECOS] Error in run tests

[Ricardo Andrino]

Ok, i will install Redboot into my board but in this link

 http://ecos.sourceware.org/ecos/docs-latest/ref/at91.html 

you can see that a redboot_RAM.elf file is created but for my board AT91EB40A (ecos configuration tool) only the ROM elf file will  be create won't it? No RAM mode image. How should i make it? I i want to run the redboot into RAM memory after i will need the redboot_RAM.elf.
Is there a guide with the full steps for redboot installation?

Thanks in advance

That page and the pages it references (chapter 3) tells you how to
build a RAM, ROM or even ROMRAM redboot. What differs is the
configuration file you import: redboot_ROM.ecm, or redboot_RAM.ecm.

That page also give you step by step instructions for the installation
process.

All the info you need is there, you just have to read it.

Re: [ECOS] Error in run tests

[Ricardo Andrino]

Hello, i have found in the documentation and Angel Monitor copy itself from flash into RAM (0x00020000-0x0003FFFF) so my program don't use the same memory area as Angel.So I don't understand why all the programs hang up.
 I want to install Redboot but first i want to run these programs ( RAM start-up)without redboot.

Any idea?

Thanks in advance.

First of, do what we have all suggested. Swap to redboot. Thats how
eCos has been tested and thats the configuration we know it works
in. Its quite possible the setup you are using now the application is
using the same memory as Angel.

That is not the correct way to build Redboot. Read the documentation.

Any idea?

Another question, i have added the Redboot package in the ecos configuration tool but if i clicked in Built Redboot ROM elf image, there are 2 error and the target.ld is not created, When i disable this option there is no problem why? I will need this file to download redboot won't i?

Thanks a lot.

Just writing to flash does not program it, you have to do special
things to program it. The only way to do it is to load a program that
can do the right things to write to flash. 

The best way to do this is to load RedBoot. Take a look at the
following documentation:

http://ecos.sourceware.org/docs-latest/ref/at91.html

You can run applications from flash, thats not a problem.

But the way the test cases are run requires the insertion of
breakpoints. You cannot put breakpoints into ROM. So its not possible
to run the test automatically. Instead you need to run the test
programs manually and manually determine if they have passed/failed.

When it comes to real application development, you will find it slow
working with your application in Flash. Again you cannot use
breakpoints, single steps etc. Its also slow writing the image to
flash every time you want to run it. Also, flash's do have a limited
number of erase/program cycles.

Its best to develop your application in RAM and then once its nearly
complete move it to FLASH for testing. It will naturally run slower in
FLASH, so you need to be careful about this.

Thanks a lot for your fast answer
but i don't understand when you say won't write anything. I want to load my program at address 0x1000000, flash memory and run my program from this memory is it not allowed?
Why does have the board the flash memory?

Thank you

Well, there's your answer: a ROM startup executable is intended to run
out of ROM, not RAM. The load address of 0x1000000 is in ROM, so the
load won't write anything, and when Angel tries to set the breakpoints
you get error messages.

Try a RAM startup application. Better still, install RedBoot.
