PROCESSOR-SDK-J721E: How to flash u-boot to QSPI using DFU

Part Number: PROCESSOR-SDK-J721E

Hi,

I'd like to flash a QSPI device with u-boot.  SPRACY5 details how to flash an OSPI device.  Is the technique similar for a QSPI device?.  Can dfu_alt_info_ospi be also used for QSPI as I see no dfu_alt_info_qspi in the u-boot source code.

thanks

    You are right. The same command can be used for QSPI as well as the offsets and sizes remain exactly the same.

    When running the dfu command we can change the bus instance to probe like below:

    dfu 0 sf "1:0:25000000:0"

    The 1:0 instance corresponds to QSPI.

    Closing this thread.
