The problem is common to both boards, one with kernel a few months old, and another newer one: Older: 4.4.12-ti-r31 Newer: 4.4.27-ti-r62 The older board I have used for many hours of experimentation with the Remoteproc/PRUs, and never had a problem. I never noticed the firmwares were not starti

[beagleboard] hostapd on BBGW

I'm still trying to figure out where the WIFI SSID is set on the BBGW so I can customize it. I see this process running: hostapd -B SoftAp0-hostapd.conf The -B means "run in the background". So that leaves the SoftAp0-hostapd.conf file. Where is this configuration file? From what I can see

Re: [beagleboard] Long booting time when no network cable is plugged

Have you configured it? It needs to know which interfaces it controls, and you need to make sure that these interfaces are not auto-started. Have you read the README in /usr/share/ doc/ifplugd ? David On Tuesday, 8 November 2016 19:04:31 GMT Paul Plankton wrote: Simple installation of ifpl

Thanks Robert! I'll give that a try when I get a chance later today. Will that possibly also solve my issue with my device overlay not applying to the slot. Everything I have looked at says that there should be no error messages when applying the overlay but that's all I get. Zach On Tuesday,

[beagleboard] Re: Beaglebone Black PRU Troubles

I think I know exactly what is wrong. You need to activate the Remoteproc PRU framework. This is no longer active by default. Robert Nelson's script which is available via Github repository will fix the problem. I have been working on detailed documentation of the entire process to activate t

I have spent a solid 12 hours trying to get the PRU's on the beaglebone to work. So far I seem to be completely stuck at the getting the device overlay to work as well as enabling the remoteproc. I have tried to piece together all of the information I have found on the internet but it is either

Thanks for the replies. I should have included this picture of the diagram: It's the opto-coupler (labelled LDR) that I'm having trouble understanding how to connect.

Re: [beagleboard] correct connection of an opto-coupler

You cannot use that optocoupler and directly drive it with the beaglebone. the LED in that part needs 60ma to function correctly. you would need to add a LED driver like what gerald has used to drive the LEDs on the beaglebone. you also need to calculate the correct current limiting resistor for 6
