The datasheet for the CPU (RK3328) on page 9 (excerpt below) suggests that it does support both pseudo and true random number generation. I don't know what's needed to get it working though.
Quote:Cipher engine
- Support AES 128/192/256
- Supports the DES (ECB and CBC modes) and TDES (EDE and DED) algorithms
- Supports MD5, SHA-1 and SHA-256 HASH algorithms
- Support PKA(RSA) 512/1024/2048 bit Exp Modulator
- Support 160-bit Pseudo Random Number Generator (PRNG)
- Support 256-bit True Random Number Generator (TRNG)
OK I think the problem might be that there is no tpm-rng module available that can be added in /etc/modules, it might be something the maintainer may need to compile and add to the kernel? Dunno, out of my depth here, but somethin' aint working right.
