Thanks Romain,

I succeeded too with Buildroot by ditching the linux-stable 4.16.18-rt12 kernel (*) for beagboard/linux 4.14.67-ti-r73 and using Robert's am335x-boneblack-bbb-exp-c.dts.
There must be some cape driver issue to resolve in 4.16.y

Like you I think that the Beagleboard organization and its TI sponsors would benefit having a dedicated mailing list around the Buildroot method of embedded Linux development. TI is a Yocto member but I prefer Buildroot simplicity. In any case, working with BBB and friends via their own resource constrained Debian distribution is an inconvenient method for any serious product development...

Cheers, Enoch.

(*) Which works for me well in another BBG case.

Hi,

I had also some issues porting my system from Robert's Debian image to a Buildroot config (using PRU).
I had to choose between TI or Robert's methods to add capes, so with device tree overlays or write a single device tree with everything hard coded.
I think it would be nice to join the effort and create a Buildroot defconfig using Robert's patches but uBoot in order to use the "capes manager" and using the same kernel config as starting point.

And sorry, I have never used the LCD cape.

Sincerely,

Romain

Hi,

Buildroot, to those who are not familiar with, is a minimalist approach to building embedded Linux.
With this approach one does software development using desktop cross compilation tools rather than rely on Gcc and friends running on the much slower BBB.
Modifying Linux drivers, creating one own's device tree is easy this way.

I had good Buildroot luck with the BBB using simple capes (for serial communication).
However, a complex cape such as the "LCD 7.0" CAP-TOUCH BEAGLE BONE" is not an easy task "to buildroot" for the formidable number of components (drivers, packages, ...) that need to be correctly selected.
I would like to create Buildroot/Linux defconfig-s where hardware support is on par with Robert Nelson's fine Debian image:
BBB-blank-debian-9.5-lxqt-armhf-2018-08-20-4gb.img.xz with /boot/uEnv.txt having dtb=am335x-boneblack-bbb-exp-c.dtb ...

Has anyone taken this BBB buildroot approach with a similar complexity LCD cape?

Thanks, Enoch.
