Hi guys,

I have use the stm32f105 to do a job on the IAP jump tp APP, and normally it works fine, but latest day, I have to disable the USB code on the APP code, then use the flash download demonstrator to download the APP, it runs OK, and then re-power on the device, APP run into hard fault at once.

And I have print the CFSR=0x8200, HFSR=0x40000000, BFAR=0x5548535f(this value seems not right). I can not use BFAR to find the error place. So any one could give some suggestion?

Not GNU tools.

You said that the statics not initialized means there is static variable or function?
