openFPGALoader VS pcm

Another way to flash the devices in Linux is to use https://github.com/trabucayre/openFPGALoader which supports a variety of cables and devices. It also supports the Xilinx Virtual Cable protocol, which allows you to use Xilinx tools like ChipScope with almost any cable.

Even though I saw multiple proposed solutions around the web, I could not get the Gowin cable to be detected under Ubuntu Linux as well, so neither the programmer nor GAO could work. I tried opensource openFPGALoader as an alternative to the programmer (but not GAO of course..), but got some issues as well (not with cable, but with certain bitstreams causing the programming to hang). So the easiest solution for me to stick with Windows version.

i could/should eventually open a ticket on the openFPGAloader indeed

Most Linux users seem to prefer openFPGALoader, but if you need GAO and the other suggestions don't work you might have to use a Windows VM, thankfully Gowin IDE supports (supported?) Windows XP/7 if you want a lightweight guest.

You might be able to use a tool like openFPGALoader to load a bitstream onto your board from macOS.

Try openFPGALoader. It works fine in Windows 10 and Linux for me. https://github.com/trabucayre/openFPGALoader

There's the open source openFPGALoader with explicit support for macOS if i remember correctly, I'm not sure if it supports all the features but it should be a good starting point.

u/PCB4lyfe all you need are just the drivers for the USB blaster. To load the bitstream you can use openFPGALoader https://github.com/trabucayre/openFPGALoader

OP, if that doesn't work, and you feel comfortable installing openFPGALoader (https://github.com/trabucayre/openFPGALoader), I can send you the GPIO demo bitstream to put on your board.

Also read about Intels PCM.. and the OPCM but I cannot determine if it supports Big Sur.. I've ran into issues after the cmake processes so the binaries fail to run.

You can monitor anything you want: https://github.com/opcm/pcm up-to the cache hit rates, memory latency and the pipeline states.

There are tools to report memory controller utilization, they tend to depend on your CPU. This might be more advanced than what you are looking for, but recently I was using this https://github.com/opcm/pcm#downloading-pre-compiled-pcm-tools to monitor memory read/write and comparing it to the same values when running a memory benchmark to get an idea of the utilization. That tool only works on Intel CPUs, there is probably a similar tool for AMD cpus.

Can you check with e.g. https://github.com/opcm/pcm whether the PCM isn't unset when you shut down the VM? Alternatively livekd and https://docs.microsoft.com/en-us/windows-hardware/drivers/debugger/-pmc

Is anyone out there running PCM utility under VMWare? AWS EC2? https://github.com/opcm/pcm

Now, if you really want to be more precise about throttling, you can use a process counter: https://github.com/opcm/pcm. You can run these commands in a terminal and see how much power your CPU is using and that's another indicator of throttle. Some workloads will hit the power ceiling of your CPU without clocking all the way to the turbo frequency. A good example in my experience is prime95. Even with adequate cooling in a workstation tower and xeon processors, my cores tend to run below the all-core frequency.
