Can you add a section to the software area that deals with building the pru firmware and loading the proper overlay with the 4.0 kernel. I have updated my kernel from your image but seem to be having issues with the overlay loading and the pru's working.

Hi Alex, it is not necessary to build the PRU firmware. If you are using Kernel 4.0 you have to do: git clone https://github.com/RobertCNelson/dtb-rebuilder.git cd dtb-rebuilder git checkout 4.0.x make clean make sudo make install

After that you have to modify the /boot/uEnv.txt file.

sudo nano /boot/uEnv.txt

Add a line: dtb=am335x-boneblack-bbbmini.dtb

Now reboot.

Thank you will try that out. Is there any chance of me being able to get the latest revision of the pcb? I will probably try to get something 3d printed as to not damage the cape and the beaglebone black. On Jul 26, 2015 3:15 PM, "Mirko Denecke" notifications@github.com wrote:

I Alex, the Rev 1.4 boards unfortunately not arrived here until now. I will inform you when they are available. You can also produce your own batch, take a look on this description: https://github.com/mirkix/BBBMINI-PCB#pcb

I finally took a deeper look. the bbbmini is not included the dtb-builder repo it is included the bb-overlays repo. Now I am wondering if I should be cloning that repo and attempting to load the cape versus the dtb. will report back.

Hi Alex,

it is in the dtb-rebuilder repo as I have written above. https://github.com/RobertCNelson/dtb-rebuilder/blob/4.0.x/src/arm/am335x-boneblack-bbbmini.dts

awright424 commented 9 years ago

it is only available in the 4.0.x branch so cloning and building will not get you the dtb
