Using GPIO 14 and 15
## update over serial
You can update a kernel that is connected a given TTY with
`TTY=/dev/MYTTY make update_serial`
This is mainly usefull for kernel running on a real board but to use it with QEMU, you have to modify the serial opt to be
`-serial pty`
and then
`TTY=/TTY_VERBOSED_BY_QEMU make update_serial`
## QEMU
You can test it with
` make run`
### Qemu with a debugger
`make debug`
# Install on sdcard
Create a FAT32 partion and copy kernel and kernel8.img
