I failed earlier with BB VIEW and Debian 8.4 because I downloaded a patched 3.8.13 kernel from element14 (formerly Newark). element14 is the current vendor of the BB VIEW cape. The patches are offered at https://www.element14.com/community/docs/DOC-67958/l/element14-bb-view-lcd-cape-software-download-centre1 . Idiot me, I thought these were current.
I then attempted to follow instructions found on element14's bulletin boards to install the patches. Most or all of the destinations to which posters advised to install files found in http://downloads.element14.com/downloads/bb-view/BB%20VIEW%20Debian%20Image.zip?COM=BeagleBoneBlack were non-existent either in 7.9 (which pre-existed on BeagleBone Black) or in 8.4. Eventually I figured out where to install the files, however note that I most certainly ended up replacing something in 8.4 that was not meant to be replaced. It appears that the patches were targeted solely at 7.9. What I ended up with in 8.4 was, past a display calibration screen, a working BB VIEW with LCD4. However X would not start. I only had the login prompt. So, I could not understand whether the touch was working or not. I then found a statement from someone apparently at element14 who is responsible in some way for BB VIEW. The statement was "BB-VIEW is supported (with patches [...]) on kernel 3.8.13 [...] Support for BB View on 4.1.x kernel is not yet available." https://www.element14.com/community/community/designcenter/single-board-computers/next-gen_beaglebone/blog/2015/05/20/beaglebone-black-with-the-bbview-and-the-new-beaglebone-debian-image#comment-68910 Therefore I reverted to 7.9. I just now followed Robert's instructions. I started with the 8.4 image downloaded from https://debian.beagleboard.org/images/bone-debian-8.4-lxqt-4gb-armhf-2016-05-13-4gb.img.xz . I modified two lines in /boot/uEnv.txt as above. I didn't edit /etc/X11/xorg.conf because it said DefaultDepth 24 and contained no instances of 16. I made absolutely no changes to anything else on the distribution, only the two lines in /boot/uEnv.txt . I then booted off the SD card. What I got was a half-screen-wide calibration screen, followed by a half-screen-wide desktop. That is, the image on the screen contained the entire Debian desktop, but was 240 px wide and 272 px tall, compressed along the x axis. The orientation was normal and the cursor tracked correctly. Also, the Ethernet-over-USB link did not start correctly. On my Windows host, I saw the host's IP address as 169.254.240.185 and not as 192.168.7.1 as in 7.9 (with BeagleBone itself being 192.168.7.2 in 7.9). I then rebooted the BeagleBone again, and this second time the Ethernet link came up as 192.168.7.1 / 192.168.7.2. But, I still have the half-size display image. A number of error messages are output to terminal before X starts, filling up most of the screen (this was also the case earlier with 8.4, but not with 7.9).
