How to debug qspi flash application using segger jlink

[ganes_rames]

HI ,
    I try to debug qspi flash application using segger jlink and mcuxpresso ide, i can't able to flash/debug correctly.

the same issue mentioned in this thread. 

Am i missing anything ??

Note : When i try to flash the generated hex file manually by using segger jflash, i can able to flash successfully. But i cant able to flash/erase chip from mcuxpresso ide using segger jlink for QSPI. For hyperflash segger jlink works well.

Hi @mayliu1 ,

      I am using jlink version 8.10. In this thread they said earlier jlink V7.68c software and it used to work perfect.

Can you please help me to solve this issue with my current jlink version.

Hi @ganes_rames ,

Thanks for your reply.

The MIMXRT1050-EVKB development board uses the on-board Hyper Flash by default. If you want to use QSPI NOR Flash, you need to make changes to the hardware. It also need different algorithm files when paired with Flash of different attributes.

 RT-UFL  is mainly targeted at the Segger J-Link debugger.

The author of this article used J-Link version v6.86f. It is recommended that you also use this version.

RT-UFL v1.0 download address： 

https://github.com/JayHeng/RT-UFL/archive/refs/tags/v1.0.zip

J-Link driver download address:    

https://www.segger.com/downloads/jlink

After installing above drivers, the next step is copy all the files under the path of \RT-UFL-1.0\algo\SEGGER\JLink_Vxxx and overwrite them in the \SEGGER\JLink_V686f\ directory.

We need to specify the J-Link v6.86f driver with the RT-UFL  algorithm patch applied to  the IDE(to replace the built-in J-Link drivers in each IDE), we can realize this with the help of the JLinkDLLUpdater.exe software.   You can also set MCUXPresso IDE as my previous post.

Wish it helps you.
