that it provides /dev/random. The following configuration will enable
the TRNG, /dev/random, and the simple test of /dev/random at
apps/examples/ranadom:
System Type:
CONFIG_SAMA5_TRNG=y : Enable the TRNG peripheral
Drivers (automatically selected):
CONFIG_DEV_RANDOM=y : Enable /dev/random
Applications -> Examples
CONFIG_EXAMPLES_RANDOM=y : Enable apps/examples/random
CONFIG_EXAMPLES_MAXSAMPLES=64 : Default settings are probably OK
CONFIG_EXAMPLES_NSAMPLES=8
