Hi,

I'm starting to develop ARM controller and going to buy jtag for ARM. ARM core will be NXP or Atmel. Please advise which jtag is the best and reliable. 
1) J-Link from IAR
2) AT91SAM-ICE from Atmel
3) uLink-2 from Keil
4) ARM-JTAG-EW from Olimex
5) and other jtag


Thanks,
pak

J-Link from IAR and the  AT91SAM-ICE from Atmel there are J-LINK from Segger,if you want to use Cortex-M3, the best is to buy J-Link from Segger ver. hardware 8 because it supports better SWD.

Thanks digitalmg for your comment, J-Link (IAR) claims that it can support most of ARM whereas AT91SAM-ICE supports ARM from Atmel only, any idea about it?

Yes is true,J-link(IAR) suport most ARM and AT91SAM-ICE supports only ARM from ATMEL.I have a clone J-link ver.7 segger from china and uLink-2,with J-link I can make debug in real time, have download speed up to 600 KB/sec compared with uLink-2 which has 25k.

J-Link (IAR) supports all ARM devices but cannot be used with Keil tools.
J-Link (Atmel) supports only Atmel ARM devices but can be used with all tools.
J-Link (Segger) supports all ARM devices and can be used with all tools.

See http://www.segger.com/cms/terms-of-use.html for comparison of models.

Now, I understand that the Atmel J-link is not for general use for newbie like me. Any recommendation for ARM development board? NXP or Atmel?
