Anyway to describe the setup. I have a standard AT91EB40A(Ver 1.0 Rev 0) Eval board from Atmel. Flash is a AT49BV1614A so far - after many wrong turns i have the following ecos-2.0 installed to /opt/ecos as installed by the scripts cvs is current (21st October 2003) and located in /opt/ecos/cvs/ecos i have modified /opt/ecos/ecosenv.sh to point to the cvs Package repository Then in my home directory i have ecos/ram and ecos/rom to build the file redboot.elf (Ram version) i run the following commands: $ cd ram $ ecosconfig new eb40a redboot $ ecosconfig import /opt/ecos/cvs/ecos/ecos/packages/hal/arm/at91/eb40a/current/misc/redboot_RAM.ecm $ ecosconfig tree $ make to build the ROM files $ cd ../rom $ ecosconfig new eb40a redboot $ ecosconfig import /opt/ecos/cvs/ecos/ecos/packages/hal/arm/at91/eb40a/current/misc/redboot_ROM.ecm $ ecosconfig tree $ make then return to ram/install/bin and type $ arm-elf-gdb redboot.elf <now in GDB type> tar rdi s=/dev/ttyS0 set $cpsr=0xd3 load <the file loads> cont <escape with ^Z> < now open minicom > $ minicom <the following is the output from this command. > // ================================ Start of paste =============== RedBoot> AT S7=45 S0=0 L1 V1 X4 &c1 E1 Q0 ** Error: Illegal command: "AT" RedBoot> version RedBoot(tm) bootstrap and debug environment [RAM] Non-certified release, version UNKNOWN - built 13:41:16, Oct 21 2003 Platform: Atmel AT91/EB40A (ARM7TDMI) Copyright (C) 2000, 2001, 2002, Red Hat, Inc.

I now assume that the ram image is dumped from memory into the flash using the next command e.g. RedBoot> fi wr -f 0x01100000 -b %{FREEMEMLO} -l 0x010000 - I also noted that there are differences between my memory map and that published in the help http://sources.redhat.com/ecos/docs-latest/ref/at91.html Anyway, given that I'm new to all of this any help would be appreciated and if anyone has any specific advice on the eb40a I'd appreciate a quick email as i need to compile as much of this information into an eCos for the eb40a FAQ/mini-HOWTO, it will help the other people i'm working with get up to speed and hopefully be of some use to the community as well.

Quick hint: use official 2.0 version. This works (at least for me 8-) very well on the EB40A . I also encountered problems with CVS version and FLASH access on this board but because of lack of time I do not digged into nature of problems and cannot offer real soultion.

The command load -m ymodem -b %{FREEMEMLO} brings RedBoot in download mode. The download has to be started using minicom (key CTRL-a s). Select ymodem and select the file. You can watch the progress. After the download is complete, you can burn the image into flash.
