As Ulf wrote, the Atmel AT91SAM-ICE should do, $129.  There is also 
Macraigor Wiggler and Segger J-Link.

Hi Ulf,

Could you please tell me does SAM7X256 support DP83848CVV too?
If I connect clock output 25MHz DP83848CVV to SAM7X can I run SAMBA?
I know that SAMBA need 18.432MHz.

where does it talk about copying data between serial flash memories in
the datasheet?
Are you suggesting the following scenario :
the micro will read data from the SD card connected on SPI0_NPCS0 and
directly copy it over to the onboard SPI Dataflash on SPI0_NPCS1. So
the next time we boot, the board dataflash will contain the valid
image ready to go?

The Segger J-link would be better I think

Why do you think that?

AT91SAM-ICE H/W == Segger J-Link H/W (unless it is an old one).

The SAM-ICE firmware will check if the attached ARM is an Atmel ARM or not.
The Segger J-Link will not.

Maybe you prefer a Black or Yellow JTAG-ICE instead of a Blue JTAG ICE?

I know

Exactly. What does an AT91SAM-ICe do if it finds it is not an Atmel ARM?

It largely depends on what colour shirt I am wearing :-)

220V would be nice, but an AT91SAM9260 *is* an Atmel ARM.

Ok  so what happens if  I plug an NXP LPC ARM7  device into the 
AT91SAM-ICE?

Won't work
It is AT91 only.

Which is why I said a Segger J-link would be preferable to a SAM-ICE if 
you had to buy one.

AFAIK the Atmel SAM-ICE  are bundled with the Atmel kits  so it is fair 
enough that they only work with the Atmel parts.
