Standard Intel architecture PC running

 Linux (tested on recent Red Hat, SuSE and Debian distributions),

 Microsoft Windows NT (no earlier than 4.0 + SP6a), Windows 2000 and

 Windows XP. Linux distributions from other vendors may also work, but

 are currently untested. 

Enough  disk space for the installed

distribution. The eCos installation process

will detail the various components of eCos

and the compiler toolkit that can be installed, and their disk space

requirements.

64MB of RAM and a 350MHz or faster Pentium processor.

If you are downloading the eCos

release distribution from 

URL="http://sources.redhat.com/ecos">sources.redhat.com/ecos,

you will also need space to store that image and to compile the

toolchain and eCos from source.

Full instructions for the 

URL="http://sources.redhat.com/ecos/getstart.html">downloading and

installation of eCos on Linux hosts are provided on the eCos

website.

While eCos supports a variety of

targets, communication with all the targets happens in one of four

ways. These are described in general below. Any details or variations

from these descriptions will be found in the

eCos documentation for a specific target,

in the appendix.

Most targets will have RedBoot or GDB Stubs installed.

These normally waits for GDB to connect at 38400 baud, using 8 data

bit, no parity bit and 1 stop-bit and no hardware flow control. Check

the documentation for your target to ensure it uses this speed. If not,

adjust the following instructions accordingly.

The following instructions depend on your having selected

the appropriate serial port on the host. That is, the serial port

which connects to the target's (primary) serial port. On

Linux this could be /dev/ttyS0,

while the same port on Windows would be named COM1.

Substitute the proper serial port name in the below.

Connect to the target by issuing the following commands in

GDB console mode:

(gdb) set remotebaud 38400    

(gdb) target remote /dev/ttyS0

In Insight, connect by opening the File->Target

Settings window and enter:

Target: Remote/Serial

Baud Rate: 38400

Port: /dev/ttyS0

Set other options according to preference, close the window

and select

Run->Connect to target.

Some targets allow GDB to connect via Ethernet - if so, it will

be mentioned in the document describing the target. Substitute the

target's assigned IP address or hostname for <hostname> in the

following. Depending on how RedBoot has been configured, it will

either have this address allocated statically, or will acquire it via

BOOTP. In both cases RedBoot will report the IP address it is

listening on in its startup message printed on the serial port. The

<port> is the TCP port which RedBoot is listening on, usually

9000. It is also listed in the target document.

Connect to the target by issuing the following command in

GDB console mode:

(gdb) target remote <hostname>:<port>

In Insight, connect by opening the File->Target

Settings window and enter:

Target: Remote/TCP

Hostname: <hostname>

Port: <port>

Set other options according to

preference, close the window and select Run->Connect to

target.

GDB connects to all simulator targets using the same basic

command, although each simulator may require additional options.

These are listed in the document describing the target, and should

be used when connecting.

Connect to the target by issuing the following command in

GDB console mode:

(gdb) target sim [target specific options]

In Insight, connect by opening the File->Target

Settings window and enter:

Target: Simulator

Options: [target specific options]

Set other options according to preference, close the window and

select Run->Connect to target.

Synthetic targets are special in that the built tests and

applications actually run as native applications on the host. This

means that there is no target to connect to. The test or application

can be run directly from the GDB console using:

(gdb) run

or from Insight by pressing the Run icon.

There is therefore no need to connect to the target or download the

application, so you should ignore GDB “target” and

“load” commands in any instructions found in other places

in the documentation.
