I came to know recommended Legato AF was 16.10.3 with firmware release of 14.
I have taken 16.10.3 legato AF and mangOH 16.10 from github.
I am able to build legato AF, while coming to mangOH
given “make --include-dir=$LEGATO_ROOT wp85” to build. But its giving error

can anyone help me out regarding this one.
which version of mangOH is recommended.

I have tried to update firmware release 14 with fwupdate download 192.168.2.2 (legato AF 16.10.3). Do we need to have same legato AF version that the module contains??

::Error::
$ fwupdate download WPx5xx_Release14_GENERIC_SPK.spk 192.168.2.2

Please help me out.

Thanks in advance.

The latest release for the WP7502 is Release 14 which includes Legato 16.10.3. There have been many Legato releases since that time and I think that Legato continues to get better. The mangOH repositories target the latest stable version of Legato (currently 17.10.0). The mangOH repositories may work with previous versions of Legato, but we don’t really put any effort into maintaining compatibility with previous releases.

It’s unfortunate that the WP85 and WP750x have not had a new release in so long. It’s not clear to me why that’s the case. Perhaps someone will respond if you ask in the WP module forum.

thanks for the suggestion.
