Gen2wbfParser can't work for imx6sl

yan2anfei — Sat, 27 May 2017 03:22:06 GMT

hi ,

I have a Gen2wbfParser tool,which convert waveform from *.wbf to *.fw .

I convert a *.fw for imx6sl use the command as follow:

Gen2wbfParser -o imx6sl.fw mywbf.wbf //mywbf.wbf is 5bit format

but imx6sl.fw can't work well, the epdc_E060SCM.fw(old format 4bit) can work,

Is the convert tool Incorrect ?

or the my sourecode for imx6sl waveform set is wrong?

thanks & best regards!

As per the i.MX6SoloLite Reference Manual document, its EPD Controller hardware itself supports the 5-bit pixel format. However, the current framebuffer driver seems to be supporting only 4-bit format. So, only 4-bit EP displays can be supported in Linux at present.

Have a great day,
Artur

hi Artur,

imx7d can supported the 5-bit EP displays, Is the framebuffer driver different with imx6sl?

Is it possible port imx7d framebuffer to imx6sl ?

thanks ！
