Cycone V SOC NAND FLASH READ API issue

Hello, This is Pushpa... I am working on cyclone V SOC with NAND flash boot Baremetal application development. NAND boot is happening fine. I have a requirement to read NAND flash and compute the...

    Hello Aliff,

    alt_nand_flash_init status code is ALT_E_SUCCESS

    alt_nand_flash_page_write status code is also ALT_E_SUCCESS

    alt_nand_flash_page_read status returns 0xFFFFFFFF

    read operation is failing.

    How to access the command, address and data registers of NAND flash as we do in case of other interfaces like QSPI flash, i can directly send read write commands to the device and it works also.

    Where as in case of NAND flash, cyclone V datasheet does not explain much about accessing command, data and address registers. datasheet just explains what commands to send for particular operation but how to access those registers, so that we can do read write operation directly using the register addresses.gard

    Please guide.

    Regards

    Pushpa
