TWR-KV58F220M application cannot enter into interrupt

[Roger_WANG_2022]

boot: flash-resident bootloader

peripherals: uart

IDE: MCUXpresso IDE

SDK Version: SDK_2_8_0_TWR-KV58F220M.zip

boot example: twrkv58f220m_tower_bootloader

Application example:twrkv58f220m_led_demo_tower_a000

Tool: KinetisFlashTool.exe

after update, four led blinks one by one, everything was all right. But when i add some other resource (for example SPI), application was stop in the DefaultISR. What's the reason? why application cannot enter into the right ISR?

Kind regards,

Roger

Hi Roger,

There are several SPI examples in SDK_2_8_0_TWR-KV58F220M. Do you have reference to its peripheral initialization code and interrupt settings?

You can upload a simple test project so that I can quickly analyze the cause of the problem.

Hi,Robin

I think i have find the bug. It's the startup file problem.

the example twrkv58f220m_led_demo_tower_a000 use "startup_MKV58F24.S".

and normal example use "startup_mkv58f24.c".

the SDK support two different example based on "KSDK driver" or "transactional API".

the difference is "KSDK driver" use SPI0_IRQHandler directly, "transactional API" use SPI0_DriverIRQHandler which not define in "startup_MKV58F24.S".

I hope NXP engineer can fix this bug. I waste nearly one week time on this problem, hope these can help other NXP users. Thank you!

Best Regards,
Roger

Hi, Robin

Thanks for your reply. I use "dspi_interrupt_b2b_transfer_master" from SPI examples in SDK_2_8_0_TWR-KV58F220M. And the test projects are attached.

I also search some relate topic,

https://community.nxp.com/t5/S32K/s32k148-bootloader-to-app-can-t-work-interrupt/m-p/1165845

unfortunately don't get the right answer.
