Hi Benjamin, The reason that you are getting those problems is because of the lack of support for Beaglebone for the Ethdriver component. The picoserver application uses the Ethdriver component to interface with the Ethernet device and the component itself relies on the Ethernet drivers located inside our 'util_libs' repository (see https://github.com/seL4/util_libs, in particular the 'libethdrivers' folder).
I have tried to add support for Beaglebone to the Ethdriver component but gave up due to a high effort-to-benefit ratio and also the task not being of a high priority. The Ethernet drivers for Beaglebone are outdated and requires a rewriting effort to get it to work well with the PicoServer and Ethdriver environment. Currently, we do not have plans to resolve this issue. If you wish to undertake the task of rewriting the Beaglebone Ethernet drivers, there is a pointer I can give you. You would need to remove the existing coupling with the lwIP library. The drivers use portions of the library and this may conflict with the PicoTCP library. See util_libs/libethdrivers/src/plat/am335x/lwiplib.h and util_libs/libethdrivers/src/plat/am335x/cpsw/cpswif.[c|h].

Any help is very much appreciated. Best regards, Benjamin P.S. The file projects/util_libs/libplatsupport/plat_include/am335x/platsupport/plat/timer.h contains the static UNUSED timer_properties_t dmt_properties which caused errors on compilation too. (I deleted the lines since they arent used anyways)
