[meta-ti] Poky and meta-ti advice for Beaglebone Black

[Tsai, Matt]

Leo,

Thanks for sharing the experience.
Questions:

  1.  Do you set MACHINE ?= “am3335x-evm” in local.conf and build core-image-minimal? Or other image target is used?
  2.  Do you have to modify anything to make Linux OS (not bootloader) Ethernet and USB to work?

I used poky tag “sumo-19.0.0” and meta-ti tag “ti2018.02” and set MACHINE ?= “beaglebone” to build core-image-minimal. The USB host does not work. I wonder if I am using a good base to start with.

Also, a question about the Linux kernel meta-ti/recipes-kernel/linux/linux-ti-staging-4.14/defconfig content:
The original in “ti2018.02” tag is “use-tisdk-config= ti_sdk_omap2_release”. But I also see people changing it to “use-tisdk-config= ti_sdk_am3x_release”. I tried both, but USB host working. So I wonder what is the correct one to use?

Thank you for your help!

Matt,

I've been having some success with the "rocko" branches (meta-ti, etc), and using the "am335x-evm" machine for beaglebone black.

I haven't done any i2c yet, but Ethernet and USB are working fine. I'm still on the left of the learning curve though, maybe someone else on this thread has better advice.

Hi all,

I am new to Yocto and was trying to use poky and meta-ti to customize Linux to run on Beaglebone Black. There are a couple of questions I encountered, hopefully I can get some advice here:

  1.  What is the recommended poky and meta-ti branch/tag to use?
  2.  If we need to enable some common device support such as Ethernet, USB host port, I2C, …etc., what do we need to modify on these recommended poky and meta-ti software?

Thank you for your help!
