dear Artur,

the 320_R137_TC1.fw is 5bit waveform,  It  can't work .

the older  waveform SCM060.fw can work which is 4bit format.

Is the imx6sl platform can't support my e-ink display screen. or the sourcecode need to Modify.

thanks & bestregards,

After further studying the case, I've found the following. 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.

No, the BSPs support only the .fw format.

Hi ,

when i decompression 320_G087_AB0203_ED060XG3T1_TC-NG.fw.zip, I got a file 320_G087_AB0203_ED060XG3T1_TC-NG.fw but the file size is 4.75MB. Is it right? because original file size is 234KB.

Yes, this is right. The reason is that the .wbf file contains the symbolic description of a EPD control waveforms, whereas the .fw file contains the representation of a waveforms in binary format, that is much more larger than the symbolic one.
