Logic Sniffer Image Loader

Logic Sniffer Image Loader    -   Download Binary    -    VC6 Source Download

I like tweaking FPGA's, and so frequently download new images to the Logic Sniffer.   However, I found the command line ols_loader tool a little awkward.  So I wrote something a little easier to use:

Logic Sniffer FPGA Image Loader

The Logic Sniffer Image Loader updates the FPGA flash ROM and the PIC firmware.  It supports the common image files formats, plus Xilinx native FPGA *.bit files.

Select your port number, and the image file to upload.   Prepare the OLS by holding down the UPDATE button while pressing & releasing the RESET button.  Release the UPDATE button, then click "OK" & watch it go.

The loader verifies the OLS, performs a self diagnostic, optionally does backups on old contents of the FPGA flash ROM (or PIC firmware), and then uploads the new image.   Lastly, the OLS is returned to normal run mode so it can be used immediately.

Advanced options control backing up old images, self test, etc...   Enjoy!
