Zynthian Buster Raspberry 4 test

Hi,
I make a new thread to tell all working plugins and problems.

I download the nighty build 587.
I have official zynthian kit2+.
First run:
Zynthian boot, encoder not working -> go to webconf and set kit V2+, encoder now works :slight_smile:

With my personnal build, wifi does not works -> same here when going to webconf and try setting wifi hotspod, I get can’t start Wifi hotspot. Will try to look later.

Aeolus works only if I run ssh -X -> issue 58

For Dexed, I try to compile but had a message about missing file /lvtk.synth.hpp
Internet tell me I need to install lvtk-dev, same error, I change the makefile of Dexed, replacing all lvtk-plugin-2 by lvtk-1
The compilation seems ok, lv2 plugins is created but don’t work on Zynthian.

i noted that some weeks ago and reported on Debian tracking system:

https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=931810

As you can see, there is a kind of patch available, but it’s not integrated yet. I will push that ASAP :wink:

Regards,

Regarding the dexed compilation problem, perhaps @C0d3man can help with that … :wink:

I really would like to help but I don’t have an RPi4. I also currently have no free RPi for buster and testing… But next week I can take one from my office for testings.

lvtk-dev is the library which handles all the LV2 things, so it is easier to parse all the needed TTL-files. Can you try to load dexed with jalv? Or what does “don’t work on Zynthian” exactly means? Do other synths work with jalv?

Regards, Holger

For moment I don’t have time to test.
Other plugins works normally.
When start dexed, the logo on zynthian move all the time, I can’t back with the encoder.
I try with MOD-UI, same error.
I will put log next time I run some test.

Wow - your response was very fast! :smile:

Ah, ok. Good to know.

Ok, I see: I have to buy my first RPi4 and have to setup a new testsystem…
@jofemodo: Do you sell v3 kits with RPi4(4GB)?

Regards, Holger

If you have some idea, I can test.
Do you think the problem can be compilation flag:
The makefile have the compilation flag for all Raspberry except 4:

Raspberry Pi B+, Zero, etc

ifneq (,$(findstring armv6l,$(machine)))
CPU = -mcpu=arm1176jzf-s
FPU = -mfpu=vfp
endif

Raspberry Pi 2 and 3

ifneq (,$(findstring armv7l,$(machine)))
model = $(shell sh -c ‘cat /sys/firmware/devicetree/base/model 2>/dev/null || echo unknown’)
ifneq (,$(findstring 3,$(model)))
CPU = -mcpu=cortex-a53
FPU = -mfpu=neon-fp-armv8
else
CPU = -mcpu=cortex-a7 -mthumb
FPU = -mfpu=neon-vfpv4
endif
FPU += -mneon-for-64bits
endif

Maybe we need to tell the compiler the good CPU?

I havn’t took a look at specific compiler options for the RPi4 yet. But perhaps they are the problem. Why not removeing all options and see if it works? Optimizations can be done later.

Regards, Holger

Not yet, my friend. Aluminum case is been redesigned and manufacturing take some time too. And of course, a new case with new RBPi is enough for adding a unit to the kit number: v4 :wink:

For sure, not before 2020 …

Regards,

Hi C0deman,
I remove all flag in the makefile.
run command make clean, make and make install

When running, Zynthian logo run continuously.

It seems like the lvtk library is not compatible. Is the used version installed from Raspian or from github?

Regards, Holger

Ok. Perhaps I should wait… until they also fixed the USB-power-problem , perhaps.

The lvtk is from Raspbian.
I remove from my system, clone lvtk, build and same problem.

In the master src directory, the file synth.hpp does not exist, I look on branches, and find the branch 1.x with this file.
I clone this branch, make the build, and when building Dexed, I did not found the file lvtk-plugin-2.pc -> lvtk have lvtk-plugin-1.pc, I rename and Dexed builds and works :slight_smile:
I make a pull request https://github.com/zynthian/zynthian-sys/pull/116

@C0d3man thanks you for the advices

Very cool! Thanks for trying and fixing @lguyome45!

AFAIK, the LV2 libraries are compiled from fresh code in the build process. Zynthian images doesn’t use the LV2 from the distro.

Regards,

I think I need to burn a new image, I made many test, and I maybe make some mistake that avoid dexed to compile normally.

I check the log of the last build ofr lvtk:

lvtk lib is compiled from source but the file synth.hpp that is needed by dexed does not exit in this branch.

The modification I made, compile an old branch of lvtk to make Dexed compile ok
