Hello mate,
I must program arm SAM9XE512 for thesis project; this is my first time I program an Atmel. Could you help me? Can I program it without jtag but only by usb? Which is the software to program it?Sam-ba?
Thanks in advance!

with sam-ba you can program the internal flash, but i would recommend to buy an jtag-ice because of the possibility to use it for debugging too.

then can I program it without load any firmware for usb comunication?What programming tool do you advice me?Have you got any example code?Thanks.

sam-ba is already included in the internal rom. you only have to be sure that GPNVMBit[3] = 0 (which is done by erasing the flash). after flashing you have to switch GPNVMBit[3] = 1 to execute from flash.

if you use the jtag-ice (like j-link or sam-ice) you can program the flash without erasing and setting GPNVMBit[3].

Perfect, what program do you advice me to write the code? Have you got any example?

>>Perfect, what program do you advice me to write the code? Have you got any example?

Download the dev kit materials (AT91SAM9XE-EK) and at91lib.

You can use tool chains from Keil or IAR, Keil has examples for most of AT91SAM9 boards/families.

You could also use GNU/GCC or Linux.

But honestly it sounds like you need to learn to walk before running. Crawl the ATMEL sites, download and digest the technical documentation for the chip, peripherals and ARM9.

Hi, Thanks your precoius help. I already downloaded and read datasheet; I've prepared the schematic (in attach) to flash with Sam-ba.

To write the code to flash with sam-ba I downloaded MDK-ARM, correct??

An other advice: I would visualize final result on LCD, which is the easiest way to use it?

Thanks in advance.
