Directly by wildfire board blast today, I use a wildfire F103 development board, wrote a small program, serial port detection and DAP simulator write programs to burn to Flash, then downloader connect one end of the computer USB unplug, connect one end of the development board not unplug, programs can run normally, interactions with the data of the serial interface screen function, perfect realization with next, I'm just in a simulator program wrote F429 burning the core plate, the result is GG , why do you say that? I find this problem for a day, thought it was where their mistaken, repeatedly change program, find problems, assistant serial debugging repeatedly, then directly with serial interface screen debug, failed, thief depressed in my heart, everything looked, but couldn't find problem (had revealed the endless tired!) And you want to know whether this how to return a responsibility? Eventually the night when the problems found at noon! You guess what? The original ah, wildfires F429 the core board very strange! After I use the same DAP simulator burning program, one end connected to the computer USB pulled (power), then connect the core board did not pull out the end, the core plate at this time, no matter what is can't run, not achieve the function of what you want (gas gas! ) only connect both ends or at both ends don't pick up to normal operation of the program (what the hell? With so many development board, core board, for the first time to see such a situation, and wildfires F103 development board is not like this!) Problem, look for a day!!!!!! Alas, gas gas! Now finally find the problem, otherwise, may be can't sleep, really serious! ,最后说一点,野火的板子做工质量这些都挺不错了,唯独今天这个问题,我是真的,,,
CodePudding user response:
Fortunately, use the boards
CodePudding user response:
Response to them, a day,,
CodePudding user response:
Should be boot0, 1 jumper didn't answer right, has been operating system pre-installed programs
CodePudding user response:
No, no, no, no, I just pulled out both ends the emulator, core board without any jumper, also does not have the boot flash sub port, does not light, debugging time can only use multimeter to measure the pin level
