MCUXpresso 11.9.1 MCU-Link support for FlexSPI1 Secondary Pin Group Flash

Littell · ‎08-13-2024

I've attempted to compile and run the MCUXpresso 11.9.1 MCU-Link Flash driver for an RT1170 using these instructions (out-of-date, gotta go hunting for directories and files but welcome to the Wild West), only to be rewarded with the following error message when trying to attach to a target board:

WARNING - uknown version of flash memory device in driver image (v.0x0)

This error message came from trying to attach to a target using the Debug build of iMXRT117x_FlexSPI_SFDP. A Release build using "MIMXRT1170_SFDP_QSPI" as described in the ReadMe.txt won't even compile. Sigh.

So MCUXpresso's J-Link can't be configured to match the target's SPI Flash interface and now the MCU-LInk stuff dives down this rat hole. Extremely. Frustrating. They weren't kidding when they said that if you step even just a little bit away from the reference design you're going to be launched into lots of time-wasting adventures.

Any help?

Hi @Littell

The built-in flash download algorithm of MCUXpresso IDE can only be used in CMSIS-DAP type simulators. If you use JLink in MCUXPresso IDE, then the download algorithm can only use JLink's algorithm.

"MIMXRT1170_SFDP_QSPI" is the download algorithm of CMSIS. So your pin has been modified, it won't work anymore.

So you should change the board to an external debuger(shorted JP5) and debug it using jlink.

Hi Hang,

There may be a misunderstanding - I *am* using an MCU-Link and trying to get it to work with a Secondary Pin Group Flash.

Hi @Littell

I'm sorry, I misunderstood.

According to the error message prompt, there is a problem with the current download algorithm. May I ask if you have changed the flash?

Please re-read my original post. I need MCU-Link support for SPI NOR Flash connected to the FlexSPI1 Secondary Pin Group. I followed the directions as well as I could in Kerry's KB article but it fails with the error message shown.

What are the correct steps needed to add Secondary Pin Group support to MCU-Link in the MCUXpresso IDE?

HangZhang · ‎08-16-2024

Hi @Littell

MCU-LINK supports CMSIS-DAP debugging protocol, and the debugger on the board defaults to CMSIS-DAP. "MIMXRT1170_SFDP_QSPI" is the download algorithm of CMSIS.

To better address your question, could you please tell me which article you mentioned about Kerry?

This is Kerry's article: https://community.nxp.com/t5/i-MX-RT-Knowledge-Base/RT1170-flexSPI1-secondary-QSPI-flash-debug-flash...

It's written for an older version of MCUXpresso (11.8.1) but I was able to find the needed files and make the modification to support the Secondary Pin Group. However, attempting to use the modified driver resulted in the error message:

WARNING - uknown version of flash memory device in driver image (v.0x0)

The question (once again) is what are the correct steps to create a working driver that is modified to support the Secondary Pin Group?

Hi

I have generated a cfx file based on the document, you can try it.

If it still doesn't work, change project LPCXFlashDriverLiB to debug mode and compile it. change project IMXRT117x_FlexSFDP to debug mode and compile it. Change option0 and option1 to the corresponding mode, run project IMXRT117x_FlexSFDP, it will debug the test_main.c.

Beyond that I can't offer much. I don't have time to debug your code. I barely have time to debug my own!

Did the error messages I posted indicate the cause of the problem?

HangZhang · ‎08-26-2024

Hi @Littell

This error message indicates that there was an issue during the initialization of the flash driver.

So I suggest you debug it.

Change project LPCXFlashDriverLiB to debug mode and compile it. change project IMXRT117x_FlexSFDP to debug mode and compile it. Change option0 and option1 to the corresponding mode, run project IMXRT117x_FlexSFDP, it will debug the test_main.c.
