Hello, I'm away from my computer at the moment, but I got my Glasgow about a week and a half ago, and tried it out the day I got it. I haven't done much since other than trying out some tests. I'm a software developer for work, but I haven't done anything embedded outside of hobby stuff (so far, but maybe I can do some at work sometime in the next year or so).

I've done a bit of Arduino development, some fpga firmware fixing on my system76 laptop (mainly with directions), and a bit of Raspberry Pi stuff. I've done some hobby embedded programming at the local Rust meetup, but that's the extent of my experience so far and I want to get more into this stuff. I think I'm (definitely) out of my depth here, but the Glasgow seems super cool! 

I want to get gud with this to where I know what I'm doing, but right now I'm kinda in the "solution looking for a problem to fix" stage.

I haven't plugged anything into it yet, and need to figure out what I want to plug in to try something real out. Running it by itself, I'm getting these errors when going through the basic usage examples:

```

```

(At this point, the user LEDs turn off, but the status and VIO LEDs are still on. Resetting gets the user LEDs back)

```
$ glasgow safe

What can I do to fix this? Do I need to plug spi and uart things in for those basic examples to work or am I doing bad things?
