Linux/AM4376: QSPI Quad Write Support for QSPI Flash

Ryan Barnett96

Part Number: AM4376

Tool/software: Linux

We have incorporated a Micron MT25QU01 128MB QSPI Flash part into our hardware design that contains a AM4376 Processor. The QSPI Flash part support the QUAD INPUT FAST PROGRAM in either 1-1-4 or 4-4-4 mode. Looking at the QSPI controller it mentions support for quad reads but doesn't mention anything about support quad writes. Is this something that is possible with the TI QSPI controller on the AM4376? Or are we limited to just using a serial flash write (single SPI)?

Thanks,
-Ryan
