BBB and Chipsee 7" Cap Touch

I am trying to get the chipsee 7" cap touch lcd to work on my beaglebone black. The board is a rev A5C.

I added the dtb entry to uEnv.txt and did the command line to update x. Not sure that second was needed because x isn’t supported, but did it anyway.

The screen now turns on during boot, but nothing ever shows up.

I don’t need a GUI I just need a frame buffer. I tried doing the cat /dev/urandom > /dev/fb0 and it first said no more room on the device. Then each time I did it after that it just spewed random stuff to the console.

I rebooted and now it just always says: cat: write error: No space left on device. I assume that is because fb0 isn’t really connected to anything.

I am running the latest stretch 9.5 image from here:

Specifically I am running this one: Debian 9.5 2018-10-07 4GB SD LXQT

Can someone tell me how to get frame buffer to work on this setup?

Did you try on the latest images

Having the same problem with the latest image (Debian 10.3) Any ideas?

Sorry, the old directions where:

dtb=am335x-boneblack-bbb-exp-c.dtb on the /boot/uEnv.txt

With the conversion to using v4.19.x this will not work today..

I need to go looking for my old Chipsee cape..

In the meantime, downgrade to v4.14.x-ti by running:

sudo /opt/scripts/tools/ --ti-channel --lts-4_14
