I will have a go at that now. Thank you
John Z Nash
@JohnZacharyNash
Changing to NMEA worked!
I didnt have to disable auto config/manually port baud rate
when I wrote to NMEA it worked instantly
John Z Nash
@JohnZacharyNash
it does however seem to be getting a 10 GPS sat count, then 0, then 10 again repeatedly, I am not sure if this is normal
John Z Nash
@JohnZacharyNash
Here is a video of the strange issue
Vinicius Juvinski
@juvinski
fist of all, are you inside a house/building? there is a message on the messages panel of mission planner ?

Hi @juvinski, here is a screenshot of what is happening
This is during me walking it around outside away from trees and buildings
Along with the message tabs
It is strange because it is in a pattern, but shows miles away from the location (when it has no fix) then goes back to the correct location. The messages show the GPS reconnecting on pattern

@juvinski
your main problem is interference on the uart signal.
what uart are you using ? are you sure that there is no console on this uart ? because ardupilot is loosing the commuication with the gps and regain after a while
John Z Nash
@JohnZacharyNash
I am using UART1 I think
Yes UART01 or ttyO1
this happens after restarting so I do not believe there is a console on it
John Z Nash
@JohnZacharyNash
I have just swapped it to UART5 and the issue is still there

Can anyone tell me how to enable PRU properly?
I've enabled it via uboot_overlay_pru=/lib/firmware/AM335X-PRU-UIO-00A0.dtbo and dtb=am335x-boneblack-bbbmini.dtb in uEnv.txt
However I still need to run config-pin P8.28 pruout on PRU pins for them to output actual PWM (without this command the pins are silent)
Vinicius Juvinski
@juvinski
hi @JohnZacharyNash , there are any error or something on the dmesg ?
hi @positron96 could you be a little more specifig. What is the board ? What is the linux kernel version ?
John Z Nash
@JohnZacharyNash
hi @juvinski. I have fixed the problem. I bought a new GPS that is ublox and the issue is gone, steady 12 sat locks and no disconnecting error. Must have been the GPS module
A huge thank you for your help, once again
Vinicius Juvinski
@juvinski
hi @JohnZacharyNash , good news. unfortunally until today I didn't see anyone trying this sim gps module working. :(
meanwhile the ublox/ublox clones works like a charm
Paul Melnikov
@positron96
Hi @juvinski. The board is Beaglebone Black, the kernel is from /opt/scripts/tools/update_kernel.sh --bone-rt-kernel --lts-4_19
Vinicius Juvinski
@juvinski
hi @positron96 , lets go per parts.
first, I recommend downgrado to 4.14 kernel - wiht 4.19 the things are very unclear and very random.
second, to use the dtb file, you shoud disable the cape manager and the overlay - comment this 2 lines on your config file - because if are you loading a dtb and enable the cape manager, the dtb will be ignored - with the dtb loaded you will not be able to run the config pin - what show me that your dtb file is not loaded - you can check this doing a ln /dev/i2c* - when the dtb is loaded there is just the i2c0 and i2c2 - if not there is an i2c1 there.
Paul Melnikov
@positron96
@juvinski Ah, I see, thanks. As I understand, cape manager is removed in 4.19, so things must be different in 4.14, which I did not use. I'll try that one.
Also, has anyone considered running Ardupilot and gstreamer streaming on BBB? My aim is to do just that (ardusub, to be precise), but what I see is that with gstreamer alone sysload is around 1.3, and ardusub alone uses 1.5 sysload. They run fine separately, but when running both, the video lags and corrupts to an unsable state. (Streaming setup is as in BlueROV, an h264 USB webcam is connected to BBB, gstreamer transfers compressed h254 stream from USB into RTSP. No encoding involved)
Vinicius Juvinski
@juvinski
are your wifi in 2.1 or 5 ?
have you checked this one ?

@positron96
I'm on wired ethernet (ardusub)
Ah, forgot to mention, the goal is to stream 1920x1080. The link above manages to stream 640x360
Vinicius Juvinski
@juvinski
I found this one - maybe can help
Paul Melnikov
@positron96
Thank you for the links! Unfortunately, they don't seem to be relevant. I got to the point where I can stream FullHD video (with gstreamer). It's just when it's running side-by-side with ardupilot(ardusub), the system chokes.
Vinicius Juvinski
@juvinski
one question, have you tried to stream a lower resolution video ? to see how would be the behavior? I'm using ardupilot on beagles since 2015, and the version 4 has increased a lot resources, and I had some clues. 1 ) sd card - Im using u3 to avoid disk bottlenecks - and they happening - once the emmc of 2 gb is too small to use linux + ardupilot. another one is to avoid start ardupilot meanwhile there are systemd/config-pin process running - if you start ardupilot before all pins are right configured, you will have a high load too.
Paul Melnikov
@positron96
I've tested with 640x480, and I'd say that it's doing fine. Lag is noticable larger that when running gstreamer alone, but no artifacts.
And I'm starting ardusub manually after setting all the pins, so this is not an issue.
Can you tell me what your load average and CPU usage are when you run ardupilot on BBB?
Vinicius Juvinski
@juvinski
the load average when booting, then waiting around 2 minutes around 1.8, then starting arducopter goes to 3.8 then go to 2.0, 2.3
