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