How different is SHA-512/224 when compared to SHA-512?

As stated by FIPS 186-4 (6.6) The only two differences between SHA-512 and SHA-512/224 are the eight 64-bit words used for initialization, given by FIPS 186-4 (; and result truncation to the first 224 bits of the 512-bit result: H(N)0H0(N), H(N)1H1(N), H(N)2H2(N) each 64-bit, and the high-order 32 bits of H(N)3H3(N).

I suggest to start by checking the SHA-512 implementation pass test vectors; then implement the truncation, and test; then change the initialization value, and test.
