Hi B,

Thanks, but I now get:

$ make BUILD_DIR=/home/matt/litex_2022/build/radiona_ulx3s/
 CC       tinyraytracer.o
In file included from demos/tinyraytracer.c:6:
demos/demos.h:4:10: fatal error: command.h: No such file or directory
 #include "command.h"
          ^~~~~~~~~~~
compilation terminated.

On the command line you need to specify where LiteX is installed:

$ make LITEX_DIR=<your local installation of LiteX> LITEX_PLATFORM=radiona_ulx3s (or whatever you are using)

Alternatively, you can edit the Makefile and make it point to your local installation of LiteX:

# find BUILD_DIR without using Python wrapper
LITEX_DIR?=/home/blevy/Programming/LiteX
LITEX_PLATFORM?=radiona_ulx3s

Ahh, OK, I was taking the instructions from here where it says:

$ make BUILD_DIR=<path where you synthesized LiteX> 

It builds now thanks.

Thanks ! (I've fixed the documentation that was wrong !)

I also came across some typo's you might want to fix. On this, in the section on OpenFPGALoader every command has openFPGALoader spelt as openFLGALoader!

Sorry, another typo in this page. In Step 2: Execute, it says:

$ lxterminal --kernel demo.bin /dev/ttyUSBnn

and should be:

$ lxterm  --kernel demo.bin /dev/ttyUSBnn

Many thanks for your feedback and for the fixes !
