Hi Pedro, I didn't find the source code for this firmware. I recommend you install the TI's Code Composer Studio ( https://www.ti.com/design-resources/embedded-development/ccs-development-tools.html ) And follow the PRU cookbook. The book from Derek's if is the first edition if I am not wrong, is focused on kernel 3.18, I bought the second edition and this is updated to 4.14 version. So to start with PRU I really recommend the PRUCookbook + CCS.
Best regards.
