When using Go 1.24, cannot build the lorawan/atcmd example. The same code appears to build fine in Go 1.23.x.

I will guess it is one of these packages:

	"crypto/aes"
	"crypto/cipher"

@aykevl any thoughts?

[aykevl]

Oof that's bad. I'll take a look.

@deadprogram can you try https://github.com/tinygo-org/tinygo/pull/4761? All the driver examples build, but I haven't verified whether they actually work. I suspect GetRandom needs a real implementation (which wouldn't be too hard, just do the same thing as the crypto/rand package on baremetal).

Closing since was fixed in subsequent release. Thanks!
