Bootloader Run Twice

[wawulong]

I have extend bootloader to about 18kB (0x3B800), and add uart module in it.

When I receive host command, I'll write a flag to flash via pstorage module, and use NVIC_SystemReset() to goto bootloader (by flag) and enter DFU process.

But the UART log that I dump on bootloader init, it runs two times. I think it reset two times when I call NVIC_SystemReset().

And the time between duplicated log is not same, it affects the host re-link action.

Is that the normal behavior?

I found there is WDT in our application and after disable the whole WDT module, it's normal while bootloader running.
