JulienC: My first FPGA blinking LED !

My first FPGA blinking LED !

New page

My name is Julien and I am a French engineer in embedded systems. My interests are in FPGA programming and embedded Linux. I will try to share my experiments on this wiki.

I am new in the FPGA world. I will try to learn and share as much as I can.

== Blinking LED ==
'''Goal''': Make a LED blink.

I used the [[Une_led_qui_clignote_avec_le_spartan_3|LED blinking page]] VHDL code to generate the FPGA binary file with Xilinx ISE. (more details are needed on this wiki to generate .bit files)

On the hardware side, I connected the 2 FPGA pins L28P and L28N to a [[wiktionary:wikipedia:breadboard|breadboard]] with wires. Those 2 pins are accessible on the DevLight bottom, as mentioned on the [http://www.armadeus.com/_downloads/apf9328DevLight/documentation/dataSheet_APF9328_DevLight_V2.pdf datasheet], page 9. Those 2 pin-holes are too small to solder [http://www.selectronic.fr/article.asp?article_ref_entier=90.0425-9999 "conventional" pins], so my set-up is quite unstable. I need to make it more robust.

On the software side, I don't want (yet) to flash my board with a new software, so I am using the default one provided (Linux kernel 2.6.27.2). Moreover I want to load the FPGA from Linux (and not [[InstallTargetSoftware#FPGA_firmware_installation|from U-boot]]).
I set-up a [[MultiMediaCard|microSD card]] to transfer my files. to load the FPGA binary file, in addition to the .bit file, I needed the [[FPGA_loader|fpgaloader]] driver script which seems not to be by default on the board.

After booting the board, I use the following commands:
# mount -t ext2 /dev/mmcblk0p1 /mnt/mmc
# cd /mnt/mmc/root/
# ls
Clk_div_led.bit fpgaloader.sh
# sh fpgaloader.sh
fpgaloader module v0.0.6 successfully loaded !
# dd if=Clk_div_led.bit of=/dev/fpga/fpgaloader
255+1 records in
255+1 records out

And it blinks!
