I'm trouble shooting a problem on a simple cape for a BeagleBone Black. I have a bipolar switch for an LED, very similar to that used for the "User LEDS". So I have added an approximately 10Kohm load to one of the "boot pins", which in header lingo is P8_44.
P8_44 is also one of the "boot" pins. I'm interesting in using the PRU connection mode of this pin. The System Reference Manuals says the boot pins must not be *driven* prior to coming out of reset (SYS_RESET goes high). So maybe my understanding of the term "driven" in this context is incorrect, and it could also be interpreted as "loading", as in excessive resistive loading? I tried an experiment on both BBB and BBG with a 10kohm resistor to ground on P8_44. Both refused to boot up and run. So is it a requirement to keep resistive loads off this pin during the boot process?
