DVI-D has the exact same TDMS signals as HDMI, it just adds optional analog signals (to implement the full DVI-I interface) and drops the CEC remote control interface. I understand the difficulty with keeping the device small! > Another possibility would be to split the eMMC into multiple partitions, one containing the regular OS and the other to store an update image. The system would initially boot into a RAM disk, determine whether an update image is present, extract that over the regular OS partition and reboot. The update image could be deployed via ssh. I'm less concerned about update images and more about backup images. If an update has been created, I'd want to be online with the machine anyways to test the change and I'd have no problem using ssh to develop and deploy. What I'm more concerned about is whether I'm going to get a call from the third-shift maintenance on a Sunday morning if the label printer stops working and the HMI shows "FAULT: Print Computer Watchdog Timeout". I suppose I could create an image that would do nothing but boot from eMMC to a ramdisk, look for a backup image on the micro USB device, and overwrite the eMMC with that image (if found). They couldn't set up a new spare without contacting me, but they could keep that on their shelf...
