Author here. Yes - the obvious way to wire up the internal display of the MNT Reform would have been to use eDP directly, but since that would require use of the blob, they used the i.MX8M's MIPI DSI interface instead and used a DSI to eDP converter.
Shouldn't you have mentioned this in your article? The way the article is written makes it sound like the MNT Reform is flawed in a way this clarifies it is not.
Not sure what you're referring to. As I state in the article:
>Therefore, it is impossible to ever replace the HDMI blob used by this device. The device could be used without this blob, but you then forego use of the HDMI (or DisplayPort) functionality.
If you use the MNT Reform without the blob you can never use certain features of the device, namely the external HDMI port, so it's not as though the MNT Reform is without flaws. In any case the article is about the i.MX8M, not any specific device.
You explicitly mention the MNT Reform and the Librem 5, which use this chip. I agree that you never say that any given device can't work around this, but that is what I understood from the way this was presented. I was vaguely familiar with the MNT Reform and went looking for that converter chip because I thought they had a solution to this, which they do.
Perhaps if the last bullet point in the article said something about not being able to use HDMI or displayport without a converter chip, it would have been clearer to me.
