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.

That's the Chinese clone, isn't it?
Yes, Chinese brand, which use CORTEX-M3 architecture .
Looks to have some better features to be honest. And they have several different models/families
yes, they support USB features very well, but until now, I have to find out strange problem reason for it.
