MSP430F1232 can't set breakpoints, register write fails, I bet you haven't encountered this problem...

飞过漠北的蓝天

I use IAR to write a program for MSP430F1232. I change the chip model and header file to MSP430F1232, set a device model in option, and then include the right .h header file. Generally, it can run normally. In fact, it can be compiled and simulated online, but any register assignment in the program will fail. Only during online simulation can the register value be manually set through JTAG, and then breakpoints cannot be set. When simulating, I can't see where the program is running when I stop. In the program, I just set the working mode of GPIO3 (no interrupts are used). The watchdog is turned off, and the internal DCO is used as the system clock. In fact, it doesn't matter, because writing to the register is useless. It's useless. When I simulated it, the register didn't change at all. It was always in the reset state. Even if I didn't write a sentence, just writing while (1), it was useless. I couldn't see where the program started running, because it would run automatically once reset, just entering debug mode, as shown in the following figure file:///C:/Users/MBENBEN/Documents/Tencent%20Files/1078128814/Image/C2C/LAOW1X76J461@A9LZ%60%7D_6J6.jpg The following is the prompt information in the debug log column when I just entered the program,,,, Thu May 25, 2017 11:20:59: Interface dll version 2.4.9.1 Thu May 25, 2017 11:20:59: Device : MSP430F12x2/F11x2 Thu May 25, 2017 11:20:59: External voltage : 0.0 V Thu May 25, 2017 11:20:59: VCC voltage : 3.3 V Thu May 25, 2017 11:21:00: Download complete.

The watchdog needs to be turned off. There is a problem with the project configuration.

I have said that the register cannot be written. Writing to the register is invalid

The register cannot be written, and writing to the register is invalid: Sad:

At this time, you should check the simulator settings, chip power supply, simulator driver, etc. If conditions permit, you can change a computer or create a new project file to try.

The msp430f149 can be compiled successfully without any exceptions, but there are exceptions when using it on the msp430f1232

It can be compiled and simulated online, but it does not mean it runs normally. The first thing to do when initializing MSP430 is to handle the watchdog
