==Tested RPi shields/hats==
* [[Dragino Lora/GPS HAT]]
* [[PiTinfoV1.2 HAT]]

==Tips==
===Bootstrap===
* Put ''Boot0'' jumper to go in [[Bootstrap]] mode

===U-Boot===
* Use OPOS6ULDev "User" LED in U-Boot scripts:
** ON: <pre class="apf"> BIOS> gpio set 68 </pre>
** OFF: <pre class="apf"> BIOS> gpio clear 68 </pre>

===Linux===
* to activate login in Framebuffer console, please uncomment ''/etc/inittab'' line 35 this way:
<pre class="apf">
# Set up a getty on LCD
tty1::respawn:/sbin/getty 38400 tty1
</pre>
