Why I am not able to send OPCODE command using Intel® Stratix® 10 Serial Flash Mailbox Client IP?

Description

When you are trying to send OPCODE command using Intel® Stratix® 10 Serial Flash Mailbox Client IP, you will observe that the command is not being sent to the flash correctly. 

The reason is that there is a document error on the user guide where the offset 13 (CONTROL) register of the CSR for bit [5:3] is incorrect.

The correct bit is [6:4]

Resolution

To performed read data OPCODE, you will need to set 0x4 to bit [6:4].

To performed write data OPCODE, you will need to set 0x2 to bit [6:4].

This information will be updated in the document future release.
