Hello.

I am new in ARM7. I have one AT91SAM7X256 Chip and don't have the EK (at my Country SAM7-EK are not available also the Chips availability is less and expensive). So that, I trying to make a simple development/breakout board for my code testing. My simple board will have all PIN (100 PIN) headers. Also I want to add both JTAG and SAM-BA USB Programming option. I have attached a Schematic of my JTAG and USB-ISP connection. I did not add Power, GND, X-TAL connection yet. I need your suggestion about only JTAG and SAM-BA USB ISP connections.

I'll be very glad if you please check my connection and comment, is the connection OK? Or something more I need to add?

Thank you for reading. Awaiting for your prompt reply.

Regards.
Sakibnaz.
