Questions:
Dear @mvoelkel and/or @rjkm please update/bisect both repositories to the latest commit (933779a/cd19e9e I use as example) that actually build?
Is libxp-dev really necessary for building?
The image is around 5.7MB, according to the specs there is 256MB of flash does it mean I can safely flash a firmware that is ~12MB or maybe 200MB?
Please add a JTAG "openocd.cfg" for this target/board so a Raspberry Pi user can fix bad flash or bricked hardware by hackattack.
