Hello fellow EdgeBSD developers,

Since I've just hit an important milestone in my lm32 port I figured I would send an update on the list :)

Since a few days ago, the LatticeMico32 port is able to print some text from user space ( /sbin/init ) \o/

Here is a pastebin of the boot inside qemu: [0]

There is a lot of crappy debug output, sorry about that!
I am compiling with the following debug options:
- DEBUG_EXEC
- LOCKDEBUG
- DEBUG
- DIAGNOSTIC

I published an updated "howto" which explains what works so far and how to clone the source, compile the in-tree toolchain, compile the kernel, compile the /sbin/init user space program and stuff it inside the kernel's MFS (ramdisk) etc: [1]

Here is the code of the /sbin/init which executes successfully: [2]

Cheers!
