I think both of these are good, and others like the Embedded Artists
board, the Tini2138, the Keil MCB2130, and some boards from Olimex.

But one thing that is very important should also be considered: the
JTAG device. Some use the Jlink, the Ulink, the Wiggler, etc. Once you
buy a development board you should probably buy the JTAG device that
comes from the same vendor, unless you already have a device.

The compiler tools should also be considered. Obviously, IAR has their
own tools (the 32K limited version is free), and Keil has theirs (the
16K limited version is free), and Olimex recommends the CrossWorks
tools from Rowley.

I think any of these tools can work with any JTAG device, and on any
of these boards, but you often find "bundles" that come with boards,
so you should look into this to know what comes with each board.

You frequently don't use an RTOS on an ARM7 device, but that is
possible, and many people do it.

I haven't tried this, but I understand FreeRTOS is an option.

There's even a flavor of linux that can run on an Arm7 (uLinux).

If you need a full-featured RTOS, you might be better off with an Arm9
device.
