Hello

Team！

my sys_startup.c program have _enable_interrupt_() function,but when the program run here, it down.

And my sys_startup.c have #include "sys_core.h", program can find the "cpsie if",but run "cpsie if" it down.

I read some posts about this issue.Suggest include "sys_core.h" in sys_startup.c.I have added it.

It seems that the compiler does not support assembly.

Hello Whong,

There is no problem to call assembly function in c function. _coreInitRegisters_(), _coreInitStackPointer_(), etc in _c_int00() are written in assembly code.

I don't get any problem when calling interrupt enable function from _c_int00().

Hi Whong,

If you want to step into the assembly function, please use disassembly window.

Hello

What dose case it?when progrom run here ,and run next，it down.

What are the possible causes？

Hello

when program run the function enable interrupt ，“cannot load from non-primitive location”

What does it have to do with this?

Is the problem caused by cpsie instruction?

Maybe

Give a plan, let me try

Thank you

Hello

Sorry .I find _enable_interrupt_() function if it is in the begin startup ，that is normal.

So It should be that the self-test startup has affected it.

/* Run RAD Self tests on TCMRAM */
retVal = SL_SelfTest_SRAM(SRAM_RADECODE_DIAGNOSTICS, TRUE, &failInfoTCMRAM);;
INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

retVal = SL_SelfTest_SRAM(SRAM_PAR_ADDR_CTRL_SELF_TEST, TRUE, &failInfoTCMRAM);;
INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

They influence the _enable_interrupt_() function.

What do these two functions mean, or what settings I dont make ?

Thank you

Hello Whong,

Those two functions are to do SRAM Redundant Address Decode self-test and SRAM Address and Control parity self-test. One the self-test is started, any access to SRAM will generate parity errors. So the IRQ interrupt should be disabled before performing any SRAM self-test.

Hello

Yes. I Test when delete these two functions,

retVal = SL_SelfTest_SRAM(SRAM_RADECODE_DIAGNOSTICS, TRUE, &failInfoTCMRAM);;
INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

retVal = SL_SelfTest_SRAM(SRAM_PAR_ADDR_CTRL_SELF_TEST, TRUE, &failInfoTCMRAM);;
INCREMENT_PASS_FAIL_COUNTER(failInfoTCMRAM, retVal);

the _enable_interrupt_() function can be setted in anywhere,

But safety library2.4.0.demo. Dont close SL_SelfTest_SRAM.what should I do？Close this manually？

Now _enable_interrupt_() function is after the two function.But program is still down.
