Yep, its an easy one. Your fzp file is incorrect. The file names in the fzp don’t match the real file names:
fzp file:
<views>
<iconView>
<layers image="icon/HeltecCubeCell0000_2.svg">
<layer layerId="icon"/>
</layers>
</iconView>
the file system:
$ ls
…
svg.icon.HeltecCubeCell0000_2_icon.svg
In the fzp file the layer line needs to be
image="icon/HeltecCubeCell0000_2_icon.svg">
to match the name in the file system. (except for the svg.icon part which translates in to icon/ in the fzp file) and it does not so the svg file isn’t found:
Error 15: Can not rename
‘svg.icon.HeltecCubeCell0000_2.svg’
to
‘svg.icon.HeltecCubeCell0000_2.svg.bak’
‘svg.icon.HeltecCubeCell0000_2.svg’
No such file or directory (2)
As far as I know the .fzpz file format isn’t documented anywhere, I guess I should do that …
