* The @sanvito-custom@ testscript for the BELD OS still had some issues:
** Load on the 3 Ethernet and the 4 slow RS485 interfaces was too high, making the test too sensitive to scheduling variances and causing the test to break the 1s-raster. Reduced amount of data for both.
** Removed the @i2c@ test for the proximity sensor. While physically still present, it won't be used or supported anymore (only ambient light will be used)
** increased load on fast RS485 port and GPU (@bball@) because these tests still allowed higher data-rates without performance or temperature impact
** increased load on Analog-I/O test to 10 reads of 10 median-filtered samples, each, as specified by customer as application work-load (also still possible without impact on performance or temperature)
