Semihost hard falut

[Shealtiel]

I'm using MXRT1020 board. I merged the dcp code into flex spi nor polling code. Initially I was facing the issues it was going into semi hard fault . After debug I got to know,  UART peripheral present or debug is causing the hardfault. It worked once the below function was comment out.

BOARD_InitDebugConsole();

but I want debug console as well. How can I resolve this issue????

Thanks,

Hi @Shealtiel ,

Thanks for your interest in NXP MIMXRT series.

In the information you provided, the original flex spi nor polling project was running fine before the code was modified is that right? So, is it possible, that the process of modifying the code caused a resource conflict? We suggest you try the latest version SDK code first. Then, if there is still a problem, you can provide a minimal reproduction project for our side to troubleshoot this issue.

Best regards,

Gavin

Hi @Shealtiel ,

I really apologize for my late reply.

It took some time to reorder the RT1020 EVK boards. I have reproduced your issue on my side today. And I am pushing to locate and solve this issue. Thank you very much for your patience.

Best regards,
Gavin

Thank you for your patience!

I tried switching to release mode over here, and it passed when I program it in the IDE.

Suggest you use RELEASE mode first, its root cause is still being troubleshooted internally.

Hope you have a good day！

Best regards,
Gavin

Hi @Shealtiel ,

We found the cause of this issue.  flexspi_nor_polling demo will erase the sector defined by EXAMPLE_SECTOR. After merging dcp code, the image size of demo flex_spi_nor_polling increase. So demo will erase itself.  User can increase macro EXAMPLE_SECTOR to fix this issue.
