factory bitstream arty-a7

[Carl Karsten]

I'd like to re-flash my A7 with the bitstream that was per-installed.   I'd assume it was here but I can't find it.

 

it displays this on the serial

Choose Task:

and blinks the LEDs per button presses.

The purpose is for students in a lab to start with a 'fresh' board like when it comes out of the box.

Hi,

you can download the ZIP file from here https://digilent.com/reference/learn/programmable-logic/tutorials/arty-programming-guide/start and use it.

unzip..

module sw_btn_led(
    input [3:0]sw,
    input [3:0]btn,
    output [3:0]led
    );  
    
    assign led = sw | btn;
    
endmodule

 

This is all that is there.  it is not what is preloaded into the Arty

@Carl Karsten

The out-of-box demo source files are currently unpublished, to my knowledge, but here are the bin files:demo100.bindemo35.bin 

Not sure, but bit files alone might be insufficient given these demos include a microblaze processor - the bin files include the ELFs, and I've verified that the 35T variant works on my hardware. The attached .jou file shows the TCL commands for programming a board with it. Your FPGA part, flash part, and file names/paths may vary. The manual has additional information about identifying the flash part on your hardware (https://digilent.com/reference/programmable-logic/arty-a7/reference-manual#quad-spi_flash).

Hope this helps,

Arthur

you win!

openFPGALoader -b arty demo35.bin --write-flash

that simple and my arty is just like one fresh out of the box.  Thank you.

This doc implies maybe the source is available in the wild, but I spent much time trying to find it or find someone who could help no luck.

but that's OK, I don't need the source, just the bin file you supplied, so thanks again.
