NanoPi M4V2 WiringPi broken

[jernst]

Hi!
I installed the latest version rk3399-eflasher-friendlycore-bionic-4.4-arm64-20190926.img from SD to eMMC using eflasher.
Worked fine until I tested the wiringPi library with "gpio readall" command.
Then I got an error message "winringPiSetup: Unknown model".
Seems like the wiringpi library is compiled for M4 and not for M4V2.
Is there a fixed version or is it possible for me to compile a fitting version?

Thanks for the feedback. This issue has been fixed. Please try again.

I followed your link to the wiki page and wondered why you suggested "Install WiringPi for Python".
Nevertheless I went through the install steps. At the end there was no change.
The command "gpio readall" gave the same error: "wiringPiSetup: Unknown model"

You can also download the latest firmware, which is already built-in wiringPi-python, no installation required, the latest version is 20191218

Then I got an error message "winringPiSetup: Unknown model".
Seems like the wiringpi library is compiled for auto clicker M4 and not for M4V2.

I see the same problem with "Unknown model".
The wiki still points to installing WiningPi which no longer exists.
The replacements work for the RaspberryPi 3 so may be it has to be made model aware of the M4v2.

I have now got back to this topic.
I installed wiringpi-v2.44-friendlyelec-rk3399.deb, "gpio readall" looks good.
When I try to use the library to build an application I find it's not built with libcrypt.

After 10 months I tried again.
This time using rk3399-eflasher-friendlycore-bionic-4.4-arm64-20200817.img.zip
Installation from SD card and also "apt-get" to update/upgrade the system worked fine.
But "gpio readall" showed the same ERROR!!!

Code: Select all

wiringPiSetup: Unknown model

And "gpio -v" showed this output:

Code: Select all

gpio version: 2.44

So "gpio" recognizes M4 V2 a bit, but still didn't work.
It does not make any difference if this is done as root or as user with sudo.
And no, it cannot be solved by compiling C code with my own application. Results in the same error.
Why is a fresh install of the firmware still broken?
Does anybody know how to fix this annoying bug?
