Why do QSPI commands in Mailbox Client FPGA IP with input flash address beyond the flash boundary return an incorrect response code when using the Agilex™ 7 FPGA devices? - Why do QSPI commands in Mailbox Client FPGA IP with input flash address beyond the flash boundary return an incorrect response code when using the Agilex™ 7 FPGA devices? Description Due to a problem in the Quartus® Prime Pro Edition Software version 24.1, the QSPI commands in Mailbox Client FPGA IP with input flash address beyond the flash boundary return an incorrect response code when using the Agilex™ 7 FPGA devices. This problem has no impact on device functionality. QSPI command Correct response code in 23.4 or earlier Incorrect response code in 24.1 QSPI_READ 0x9 (ALT_SDM_MBOX_RESP_INVALID_ADDR) 0x4 (ALT_SDM_MBOX_RESP_INVALID_COMMAND_PARAMS) QSPI_WRITE 0x9 (ALT_SDM_MBOX_RESP_INVALID_ADDR) 0x4 (ALT_SDM_MBOX_RESP_INVALID_COMMAND_PARAMS) QSPI_ERASE 0x9 (ALT_SDM_MBOX_RESP_INVALID_ADDR) 0x4 (ALT_SDM_MBOX_RESP_INVALID_COMMAND_PARAMS) QSPI_READ_SHA 0x9 (ALT_SDM_MBOX_RESP_INVALID_ADDR) 0x80 (ALT_SDM_MBOX_RESP_QSPI_HW_ERROR) Resolution To work around this problem, execute QSPI commands with a valid flash address within the flash boundary. No power cycle is needed. To obtain the flash density value, use the mailbox command QSPI_GET_DEVICE_INFO . Note that the returned flash density value is specified in bits while the flash address for QSPI commands is specified in bytes. This problem has been fixed in Quartus® Prime Pro Edition Software version 24.2.
