Can't launch msposd on Groud stattion NVR Hi3536dv100

[Warfull]

It seems the msposd file in the release folder is not supported by the hardware because even if the file is present in the /usr/bin folder the system answer "file not found".

[tipoman9]

Font file location has been changes to /usr/share/fonts/
Post the full log please.
I kind of don't get the idea of running msposd on the ground on NVR

@tipoman9 We use Radax/Hi3536DV100 as a Rx module for OpenIPC.

I have a 3536DV100 also. @Warfull Please let me know if there released file work on Hi3536DV100.

Ok, I'm dumb : msposd is not needed on the ground station. But the result is a bit weird :

msposd is not needed on the ground station.

That depends on you requirement.

Airunit can do the OSD stuff, you can take a look at this #13 for ardupilot

[Warfull]

It's working now. Issue was, I guess, a bad parameter passed to the proc in the telemetry file.

[tipoman9]

Could you share your ArduPilot settings to make it work?
Several users reported ardupilot latest version working with Betaflight fonts with these settings:

OSD_TYPE=5
SERIALx_PROTOCOL=42 
MSP_OPTIONS=6

[Warfull]

OSD_TYPE=5
SERIALx_PROTOCOL=42
MSP_OPTIONS=4

I use Betaflight fonts.
same result with MS_OPTIONS=6

[Warfull]

But no way to get the AHI working, it is not drawn.

[tipoman9]

AHI is not supported currently camera side on Hisilicon/goke. Not hard to port, if someone is willing to change the code a little and test it, a PR is welcomed

[Warfull]

I'de like to try to change the code but the big issue for me is cross-compilation. I've tried to do it by the way of Buildroot and OpenIPC firmware, adding package to my board in buildroot but the compilation stop because of "BR_COMPILER_PARANOID_USAFE_PATH" ; ie "Error : Unsafe Path/Library used in cross-compilation : -I/usr/include".
I don't know how to manually do the cross-compilation.

[lida2003]

@Warfull Right now, I'm stucked at arduRover #17 , and I think I might do the job if I get ArduRover done.

I have 3536DV100 also, having sata harddisk connected for DVR recording.

@Warfull
This is a known issue at the moment, the latest code does not compile, you may try with older version of msposd till we fix it.
OpenIPC/firmware@b3ab67b

Or try a standalone install, it should download the toolchain required and do the crosscompilation.
.\build.sh goke

[Warfull]

@tipoman9
Thank you, I've just tried and it compile. Right now I'm working on the camera case and a pcb to connect everything together. But I will dig into the code as soon as I can.

[lida2003]

@tipoman9 latest goke version got segfault: `

# ./msposd_goke --master 127.0.0.1:14560 --osd -r 50 --ahi 1 --matrix 11
Segmentation fault

I also ported a 3536 version which uses same gcc as rootfs, still got segfault.
