I have a problem with Crystal, if I use 96000000hz for HSI with a RTOS(UIP kernel) in MM32F103(cortex-m3) , then I meet following problems.
1:Sometimes ,if program run into function SystemInit, it will jump into hardfault.
2:Sometimes ,if program run into function _scatter, all the data copy from FLASH to RAM is wrong!!!
3:Sometimes , the program is fun.
But if I choose 24000000hz for HSI, every thing is fun, I do not know why.
Please keep to 1 question per thread!
Arrays are no different to any other local variables, and the fact it's an Interrupt function makes no difference.
Automatic variables are always on the stack
Heap is used by malloc, etc.
Allocating local arrays in an interrupt handler doesn't sound like a good idea.
ok，I try to modify it, thanks.
