Parallella Community

Some weeks ago I came across a simpler way to generate the binary bitstream file. I hadn't gotten around to trying it and testing it until tonight.

It is easier than the bootgen method in that no .bif file needs to be created, nor is a dummy.elf required. It goes straight from .bit to .bit.bin with no messing around.

I did a search on the forum and saw no references to promgen, so I thought I should share it.

promgen -b -w -p bin -data_width 32 -u 0 parallella_z7_top.bit -o parallella.bit.bin

Is anyone familiar with this tool and know of any issues with it?

We'll take a look...when it comes to binary blob tools, I tend to stay with the one that gets mentioned most by the vendor. "down the middle approach". There may be others here on the forum who have more insight.

Yes, you make a very good point. I retract my recommendation to include it, and suggest it for consideration instead.

Meanwhile, I will continue to use it until it fails me - so if we ever do consider the switch, we have data points on how reliable it may be.
