How to access the QSPI flash in PS mode?

hi, Fakhrul

I just checked the link you provided, it is not for my scenario.

We have 2 QSPI flashes connected to A10.

the 1st one is connected to the HPS dedicated pins and is used for the HPS boot from QSPI. it contains the SPL/uboot image and the OS image and also our app.

the 2nd one is connected to the FPGA dedicated pins and is used for the FPGA AS mode configuration. it contains the FPGA image which we programmed into it via the *.JIC file.

so in this case the HPS boot from 1st QSPI and the FPGA configured from the 2nd QSPI seperaterly and both work well so far.

but in other situation, we need the 2nd QSPI to store some user data.

so we changed the booting mode. we also added the FPGA image file into the 1st QSPI flash. the HPS will boot firstly then configure the FPGA in PS mode during SPL/uboot stage and then the OS and app will boot. in this mode, both the HPS and FPGA images will only be stored in the 1st QSPI, the 2nd will be used as user data storage device.

but we found in this case we can't access the 2nd QSPI flash.

this is our question.

expect your prompt response.

thank you.
