K81 QSPI Problem

Hello, we encountered the following problems when testing QSPI FLASH using the SDK supporting the K81 development board:
Development environment: IAR8.32.1
Test routine: SDK_2.2_TWR-K81F150M\boards\twrk81f150m\driver_examples\qspi\polling_transfer
The polling_transfer routine is to write the data of a sector from the flash base address FSL_FEATURE_QSPI_AMBA_BASE (0x68000000U), and then read the data from this address, compare, and judge whether the read data is equal to the written data.
Problem: The routine code has not been modified. After the code is downloaded, the test found that the read data and the written data are not equal, and then IAR SWD debugging found that when writing or erasing flash data, the first two bytes of each flash page are cc cc, theoretically all ff after erasing flash, cc shouldn't appear. After writing the data, the cc in the flash still exists, resulting in the wrong data being read.
Guess: I guess there may be a problem with the flash configuration. One is the LUT table and the other is the qspi_flash_config_t structure. Since we have not used QSPI before, we don't know how to modify it.

Hi chailiming,

  Your SDK version is a little old, now the K81 newest SDK is SDK_2.5.0_TWR-K81F150M.

   Could you please tell me which board you are test now? And your external QSPI flash partnumber?

   I test the SDK_2.5.0_TWR-K81F150M\boards\twrk81f150m\driver_examples\qspi\polling_transfer on my TWR-K80 board, the qspi is:

MX25U3235FZNI

  The erase works OK.

Hi chailiming,

  Where you get the TWR-K81F150M board?

  From the nxp website? Do you have the link?

  Could you also please provide one photo about your TWR-K81F150M board?

 As I didn't find this board from the NXP website, so until now, I still don't have that board for testing.

MX25U3235FZNI is also the same as the TWR-K80F150M board, which I have tested yesterday.

So, it should works, because totally the same QSPI chip.

About the SDK, I can't send you directly, as it needs the NDA to download it.

You already have the old SDK version, so you should have assigned the NDA with NXP, and you should can download the newest SDK:

https://mcuxpresso.nxp.com/

Please try it on your side again.

So, now it should your SDK version issues.

Please download the newest SDK, and try it again.

Wish it helps you!

If you still have questions about it, please kindly let me know!

Best Regards,

Kerry
