ARM mbed online compiler can compile but the compiled program doesn't run
Hello,
I can work on the online compiler until last night, then this morning it suddenly gave me problem. I can compile my code (it has serial connection) but when I run it, the mbed prints out garbage. The compiled program of the exact code that was compiled last week works fine.
I also can compile and save a freshly made Hello World blinky program, but the mbed doesn't/can't run it (no led turns on).
Could you advise on this please? Thank you
Be the first to answer this question.
When serial out prints garbage it usually means there is a baud rate mismatch between your micro and the terminal program.
posted by Graham S. 12 Dec 2017Hi Graham, I understand that. What I don't understand is that the same exact program that was compiled a week ago works and when it is compiled now it doesn't. I can't even run the compiled fresh Hello World blinky program, which was not a problem before.
posted by Sasha P 12 Dec 2017After save the bin file, the blinky HelloWorld program can now run by ejecting the mbed before pressing the reset button. Previously I never need to eject it to be able to run the program (I used Ubuntu 17.04). The serial example https://os.mbed.com/handbook/Serial (first example) still throw out garbage. I used putty, 9600 8bit, no parity, 1 stop bit, no flow control. Any thoughts or suggestion would be appreciated. Thanks!
Edit: I found out that by using old program and not using new helloworld program, the serial can work.not working
