Dear all, I am new to ARM controller. we have Blank PCB for AT91RM9200. i wanted to make this board up. now according to my knowledge to make the board up i required J-TAG connector and some software utility to download hex file from PC to Board. so please can any body answer me following questions: --> from where do i get J-TAG circuit's Schematic for AT91RM9200 controller so that i can made J-TAG at home? --> from Where do i get free Software utility to download code from pc to Board on board, there is two SDRAM, MT48LC8M16A2 and a Flash Memory, AT49BV6416. If any body knows different method to download hex or bin or ...... file from PC to Board please send me the link of explanation please help me, i would be very much grateful to you Regards Dharmendra
Hi You can get a schematic here http://www.olimex.com/dev/arm-jtag.html or just type "jtag wiggler arm" in google. There are a plenty of sites with schematics. That store sells the dongle for a very low cost (I bought mine there and is working greate) For programming there are several arm tool-chains like http://www.siwawi.arubi.uni-kl.de/avr_projects/arm_projects/#winarm www.gnuarm.com www.gnuarm.org www.yagarto.de Also there is an evaluation ide and compiler from www.keil.com that is restricted to 16 KB of code I hope it can help you =)

Now how can I identify which J-tag will be work with my AT91RM9200 ARM9 controller? eventually i want Schemactic of J-TAG that can work with AT91RM9200 controller? can both work with ARM9? Dharmendra
