New Errata for netX 51 / 52
5.2.1
SYS LED lights doesn’t light correctly during active Boot
Loader
Due a bug in the Boot Loader the signals for controlling the SYS LED are inverted.
This happens only if there is no firmware on the netX 51 board or during the boot phase till the
firmware is started.
In new designs this can be compensated by connecting the Cathode of the SYS LED instead the
Anode according the schematic below. This LED interface is exactly the same as for the netX 10.
