Your website only says:
"Processor 1 GHz ARM A9 CPU"
> Two from freescale for the imx6 and imx7
Ok, but you are using imx6.
> There's also another one written by lab126
Nope. That's the same driver from Freescale. You can download the kindle source to verify. https://www.amazon.com/gp/help/customer/display.html?nodeId=200203720 https://www.amazon.com/gp/help/customer/display.html?nodeId=...
> then you have the u-boot drivers.
u-boot just draws a splash screen.
> you have the 5bit waveform support, which is a whole other story (with iffy GPL implications for some vendors I won't name).
I don't understand what you're trying to communicate. Why would a EPD waveform have any GPL implications? An EPD waveform is not software, it is a set of timing values and that's it.
> the display was designed based on our requirements
I'm having difficulty understanding what that means. It sounded like you were saying E Ink designed a panel for you, but maybe what you're saying is just that E Ink had a panel that met your requirements.
- sandsmark 10y agothere are two epdc drivers in the kindle gpl releases. the source for the lab126 one is only available in the tarballs you linked (named mxc_epdc_fb_lab126.c). as for the waveforms, I'm talking about support for the REAGL (sic) waveforms. grep for it in the linux source in the tarballs you linked to. and e ink did not have a panel that met our requirements, and designed a new one after we talked with them. edit; just to be clear, we don't use the lab126 driver, it was just an example of there being more drivers for the imx6 generation epdc.
