I need help with Trace recorder library integration. I'm using Keil and STM32F407.
I included recorder library in my project but when I try to compile I got an error which I don't know how to fix. Error is in code:
asm volatile ("cpsie i");
asm volatile ("cpsid i");
void prvTraceSetIRQMask(uint32_t priMask)
asm volatile ("MSR primask, %0;" : : "r" (priMask));
asm volatile ("MRS %0, primask" : "=r" (result));
GenericRecorderLibSrctrcHardwarePort.c(65): error: #20: identifier "asm" is undefined
GenericRecorderLibSrctrcHardwarePort.c(65): error: #65: expected a ";"
Thank you for your help!
It looks like you are trying to use GCC syntax in a Keil project. IAR will generally let you do that, but Keil won't.
You need to look in the Keil manual to see what to do, but as a head start
asm volatile ("cpsie i"); can be replaced with _enableirq();
Likewise asm volatile ("cpsid i"); can be replaced with _disableirq();
I imagine there is another such intrinsic to get the primask value.
