I forgot the most important part:

Select the BeBoPr configuration and watch the pins twiddle as the PRU
does step/dir generation:

    "p8.27",        /* pru1.r30.8   Z_Step  */
    "p8.28",        /* gpio2.24     Z_Ena   */
    "p8.29",        /* pru1.r30.9   Z_Dir   */
    "p8.30",        /* pru1.r30.11  E_Step  */
    "p8.36",        /* gpio2.16     J4_PWM  */
    "P8.39",        /* pru1.r30.6   Y_Dir   */
    "P8.40",        /* gpio2.13     Y_Ena   */
    "P8.41",        /* gpio2.10     X_Ena   */
    "P8.42",        /* pru1.r30.5   Y_Step  */
    "P8.43",        /* pru1.r30.2   X_Step  */
    "P8.44",        /* pru1.r30.3   X_Dir   */
    "P8.45",        /* pru1.r30.0   J3_PWM  */
    "P8.46",        /* pru1.r30.1   J2_PWM  */
