I have been trying to use the onboard wifi amber led to show a status from my program. The latest mraa library seems too difficult to use and seems to still use the deprecated sysfs method. Now libgpiod seems the replacement in version 21.x and the preferred character devices method. I have tried using both sysfs and libgpiod to access this device which resides on gpiochip1 line 12 but I get a resource busy - presuming the kernel is holding onto it. I don't want to have to resort to creating a custom kernel just to do this. Hoping someone has experience in dealing with this issue. Thanks in advance.

I have recently found these fantastic products and was looking forward to using and promoting them in Australia.
Sadly, I have found that many other companies the direct support to contact the company is not present. In point of fact the "Support" link on the website takes you to a nice 404 page showing the lack of interest.
It is a real shame that a company that has developed some great products has failed to do the most basic thing.
BTW I tried to follow the guide to cross compile the example that was given in the documentation but even that has not been proven well. It was only when I found an article about "A Small but Important Note" that I found the answer.
If only the company was as good as their products.
