[ECOS] How to create a Bin file for downloading

[Huang Qiang]

While using eCos configuration tool and the cross compiler and linker how to
build a program to be store in the target's flash memory and start it at the
startup?
thanks

to create a binfile on ARM use: 

arm-elf-objcopy -O binary file file.bin

where file is the program in ELF format.

How to get it onto your board is board dependent. For the EB40 I don't know
I'm afraid.

Thank you Jonathan.

But...
Can I get the program in ELF format under windows 2000? How to get it?
I used to get a file name a.out. what can I do with this file.

command used to create this file:
arm-elf-gcc -g -I/c/ecos-work/E7T_install/include
led.c -L/c/ecos-work/E7T_install/lib -Ttarget.ld -nostdlib

after that I got a file name: a.out
I used to download it by using Insight 5.0 but now I want to install in in
the target's flash memory by using Redboot.

regards!

Programs created by arm-elf tools are in ELF format. So just try it with
a.out.

Atmel provides, on the EB40's CD-ROM, sources for a flash tool that runs in 
RAM. The procedure is:

* make sure the switch is set for low 64K boot
* boot Angel or GDB stubs on the EB40
* connect with GDB/Insight and upload the flasher program to RAM
* run the flasher program, which somehow accepts the new binary over the 
serial link (I think a raw binary upload, I don't recall right now).
* once complete, flip the switch and reset. (your app gets burned into the 
upper 64K of flash).

I'm 99% finished a little RAM-loaded booter application that is simpler 
(for me) to use. The procedure for my app is:

* boot the EB40's "serial bootloader" by holding down FIQ while resetting
* use the BINCOM utility to upload my app to RAM
* press IRQ0 to start execution
* use Hyperterminal to upload your binary using Xmodem
* wait for LED to go out and you're ready to go
