Starting Point? (Destiny)

After a quick look, it seems that both parts of the message are errors for 2 different things

Errors for two different things? "RX" just refers to the receive part of a serial connection, so an RX ERR would imply there's been a problem with receiving incoming data. CRC's are used basically like parity bits; it's just a small piece of data that you can calculate from the "actual" data being sent, which is also sent alongside the data. If the CRC alongside the data doesn't match the CRC you calculate from the data, that tells you that there's been a problem.

I would think that an "RX_ERR" could be thrown as a result of a "CRC_FAIL."
