Hi @snehal_p,


Thank you for posting in Intel community forum, hope all is well and apologies for the delayed in response.

Just a note, unfortunately for Nios II product it has been deprecated and would advise to move NiosV instead. More details can be found in the link below:

- https://www.intel.com/content/www/us/en/content-details/781327/intel-is-discontinuing-ip-ordering-codes-listed-in-pdn2312-for-nios-ii-ip.html?DocID=781327

However we would still try our best to get into the challenges you mention on NiosII.


First note is that QSPI flash are not the same with RAM, hence cannot be tested with RAM memory test. Instead using the Intel’s flash programmer tools (nios2-flash-programmer) to verify read/write, or execute in place to run code directly in QSPI.


Also verify the QSPI controller instantiation in platform designer and correct based address (0x1800000) which matches the memory map in linker scripts. Last but not least you can verified the read/write by flashing the Nios ii firmware into the EPCQ. (i.e., using the nios2-flash-programmer command)


Best Wishes

BB

Hello BB,
We verified the QSPI controller instantiation in platform designer and correct based address (0x1800000) matches the memory map in linker scripts.
We tried to program qspi using programmer but it fails.
Can you please share steps to verify the read/write by flashing the Nios ii firmware into the EPCQ.

Thanks,
