Hello everyone, I'm using MCUXPresso IDE to debug my program. Since the NOR Flash is connected to the Secondary group of FlexSPI1, I needed to modify the Flash download algorithm myself.
For DAP, I successfully modified the .cfx download algorithm file, and the program can be debugged through MCUXPresso IDE.
Recently, I started using JLINK for debugging, so I finished the corresponding Flash download algorithm file with the .FLM extension. I added a new device in the JLINK installation directory and used this download algorithm. After testing with J-Flash.exe, the algorithm successfully erases and writes the program.
Next, I used this new device in MCUXPresso IDE. After clicking "Debug," the program can be successfully downloaded to Flash (the program runs correctly from Flash after a reset without debugging). However, I cannot debug it within MCUXPresso IDE.it seems like the IDE doesn't recognize the program at address 0x30000000 and there's no disassembly code.
I've tried adding scripts in the configuration, but it hasn't been helpful.
Did I miss any steps, and what should I do to debug with JLINK in MCUXPresso IDE?
I would greatly appreciate your response.
Hi @Vinos ,
Which Flash download algorithm you are using now?
Do you try the RT-UFL or not?
I think you can try to modify the RT-UFL, and generate the flash algorithm, and use that jlinkscript.
