STM32F2也快要浮云了

花了一晚上时间，已经可以正常擦除、编程、读取。
下面就要做flash_loader优化。

祝贺。
请问，这些信息是怎么知道的：
Info: CPUID = 0x412FC230
Info: STM32F2 type: XL device
Info: STM32F2 revision: Y
Info: Chip-id read is 0x411.

CortexM3的CPUID位于0xE000ED00，32位
通过JTAG/SWD接口读取那个地址的数据就可以了
STM32的ID位于0xE0042000，也是32位

看了一下，跟以前的STM32F1一致，谢谢。

STM32F2的Flash擦除非常慢，可能是因为1M容量的关系，我这里测试擦除1M Flash要15.2秒。没有flash大小的寄存器。

stm32F2需要从Boot0输入高电压，才能高速烧录。
这个是EP968的强项，呵呵

flash下载优化完成，单单下载flash的速度还是有很大的提升的，使用HV的话，甚至可能可以赶上LPC1000的速度。Versaloon将要推出的Pro版本正好集成了一路可编程的高压接口，到时候可以测试一下HV模式下的下载速度。Versaloon用的flash loader也是基于CM0的指令集，STM32和STM32F2通用，以后等ST推出CM0和CM4，估计也可以很快支持。
