TI also provide instructions on building an image (u-boot/kernel/filesystem) using Yocto at http://software-dl.ti.com/processor-sdk-linux/esd/docs/latest/linux/Overview_Building_the_SDK.html I have used this to build a stripped down kernel with only the kernel drivers I needed plus a minimal

Hello, You seems quite experienced with Ethernet. I would say you got the expertise. I am interested by this board because it has two Ethernet ports. The idea is to have the first Ethernet port connected to the source (server) and the second one for cascading/daisy-chain.. Could you please tell

Thank you for the responses, gentlemen. *Dennis:* 2nd addition... ran it to those problems last spring... edition matters for certain. 1st addition uses only an outdated device tree method. I've used config-pin in the ways you've described from the IDE, but have not incorporated it into C++

[beagleboard] Powering off Beaglebone green

2020-06-18 Thread guillermito . ferrari
Hello everybody, I have a GP output of a Beaglebone Green that turns the power off when it is asserted by SW. It does its job well. However, I would like to power the Beagle off after having done a shutdown (rather than turn it off suddenly). Is there any SW/HW trick to get this behavior? Thanks
