用TI的MSP-FET430UIF仿真器,IAR FOR MSP430 V5.5,烧写程序的时候突然烧写不进去,提示The firmware on the TI USB FET does not match this software version.Do you want to update the firmware?选择否无用,选择是的话升级最后会弹对话框,显示Communication error.Check if hardware is connected.Check if debug protocol (SBW or 4-wire) is correct.这是怎么回事,还有仿真器输出的电压忽然从3.3变到3.7了,如何解决。 |
