"l2norm" => sums the square of the elements in vector X

Parameters

x_ptr	x vector input. 16bit integers packed.
out_ptr	output scalar. 32bit integer saturated at 24bits, rounded by rounding_bits.
length	Number of elements in the vectors (data samples). Must be a multiple of 4, at least 8, and no greater than 1024.
rounding_bits	Number of bits to round the output by. 0 => no rounding, maximum of 31.

Returns

kAxonResultSuccess on success or a negative error code (see nrf_axon_result_e)
