RZA1L QSPI flash programming problem


I have a problem about programming QSPI flash with either e2 studio or .bat file command system. I use Stream It kit.

it gives result succesfull download to QSPI flash but application not running.

also I couldn't see any drivers and sample example for SPI multi IO bu controller. 

any idea about these?

  • We encountered also a problem with QSPI programming with the RZA1M and JLink.
    The cause was that the program switched the QSPI chip to the QSPI mode and therfore all commands need to be sent in this mode. The Segger JLink can not detect this and fails to read or write data to or from the flash chip.
    Solution was to execute a program in RAM that sets the QSPI chip back to normal SPI operation.
