Description
Hello, I've a problem in Heimdall. When I first run it, I get permission denied, but second time it works. I guess this is because export doesn't show up in /sys/ immediately. (I tried to unexport instead of rebooting and it panics too.)
Did you encounter this problem too? Is there any plan to fix it?

Research direction
Start by reproducing the first-run permission error and the panic after unexporting, then read the Linux sysfs GPIO documentation linked in the repository description. Done means the initial export no longer produces a permission error and unexporting does not panic.
