I got the following warnings when I tried to compile without adding the quotes for atmel,* "[warning] too few spaces after comma (commas)" and when I add quotes for "bits-per-pixel" it complained the following "[error] string value is redundantly quoted with any quotes (quoted-strings)" So I added quotes for properties with comma in them. > bits-per-pixel is generic property, so you > are now selecting other bindings. Read carefully what Rob wrote. My bad, I should have inquired before arriving at any conclusion. Thanks for letting me know. Shall I send v3 by removing "- required: [ bits-per-pixel ]" in select? > > > Best regards, > Krzysztof > -- With Best Regards, Dharma B.
