 SERVs demo drivers and stuff are old. Really old. ZephyrOS 2.4.0 old, which also requires an old compiler (old binutils). sdk-ng v0.14.2 works well: https://github.com/zephyrproject-rtos/sdk-ng/releases/tag/v0.14.2
 
+## More QuickNotes on this
+
+To init get new fusesoc workspace using `fusesoc init`. Then set manifest to SERV. Then `fusesoc update`. Then you can build. Play with code in `fusesoc_libraries/serv/`.
+
+Build this from here:
+```
+/home/markus/zeph_orig/zephyr/samples/hello_world
+[markus@737d440cb9bd hello_world]$ west build -b service
+```
+convert to "hex":
+
+```
+python3 $SERV/sw/makehex.py /home/markus/zeph_orig/zephyr/samples/hello_world/build/zephyr/zephyr.bin 16384 > test.hex
+```
+
+and run using (in the fusesoc root):
+
+```
+fusesoc run --target=verilator_tb servant --uart_baudrate=57600 --firmware=test.hex
+```
