For iterative testing, that is the right thing to do.
configure the following modules as built-in: - Support for Host-side USB - Inventra Highspeed Dual Role Controller - Platform Flue Layer (ti DSPS platforms?) - MUSB DMA mode (TI CPPI 4.1 (am335x)) i configured it like that right now, but am i missing something because it isn't working for me.
To rule out anything non-obvious causing issues (and things that have all caught me before). You've confirmed that the timestamp on the newly booted kernel really is the one you rebuilt after changing the config ? And you've seen it rebuilding ? If so, can you diff the full .config before and after the menuconfig, and send it along ? Kevin can compare it to the config he's booting and testing. Bruce
Thanks for the good support today!

But after building a non-custom core-image-minimal and running it on the beaglebone black, i saw that the display works, but my keyboard doesnt. I think it has something to do with the USB OTG but i have not a clue what need to be done to get it work. Does anybody got it working yet? Kevin has been supporting the yocto BSP for us, so adding him on the cc'. That being said, I'm not sure if the BBB is in a lab environment for him, and hence no physical USB keyboard to use or test. I do have a BBB in hand. I will take a look at this issue. It seems that the usb drivers are built as modules by default. But the kernel-modules is not installed by default on core-image-minimal image. That's the reason why the usb keyboard can't work. So we have two options: a) config usb drivers as built-in b) install the kernel-modules on core-image-minimal I prefer to option (a) since it makes no sense to build them as modules for a specific BSP. But it seems that many drivers such as sound, display and usb are configured as modules in beaglebone.cfg. Do we have any special reason to do so? Should we convert all of them to built-in? No special reason that I know of. I'm find with converting them to built-in. Basic/core functionality is fine to include at all times! Bruce Thanks, Kevin
