从3.x迁移到4.1，F401RCT，Freertos，出现Hardfault #158
Open

以前是3.x版本，STM32F401RCT6，Freertos，M24C32。EasyFlash跑在4KB的24C32上，读写函数是自写使用硬件I2C的读写函数。一切正常。 现在更新到4.1，有几个问题： 1，Write Gran 应该是多少?我认为是8 2，Sector设多少合适，我用1024 3，现在单步跑到写24C32的代码会引发HardFault，BFARVALID，PRECISERR，FORCED置位；使用cm_backtrace提示freertos的defaultThread stackoverflow，但是把stack size从1KB增大到4KB都无效。
