With the new mbed revision I got Undefined symbol errors.
Undefined symbol heap_based (referred from malloc.o)
Undefined symbol heap_limit (referred from malloc.o)
Undefined symbol initial_sp (referred from entry2.o).
See picture.
When I go back to the previous revision all compiles fine.
Edit: I have never updatet the mbed code. This was the first time. After going back to previoius revision I can compile with the last revision. But the program hangs and have a strange behaviour with serial. Also in the previous revision. When I compile with the version from 07.Jul.2016 the program seems to be working fine. I use the Nucleo 411RE board.
Then after testing 07.Jul.2016 revision I have gone back to the newest revison - without changing the code and when I use the serial line it hangs immediatly.
I use library classBufferSerial : public Serial.
There is nothing special in. Only _buf = new unsigned char[ bufferSize ]; which maybe uses malloc???
Then I have another function which uses:
cmd_tbl = (cmd_t *)malloc(sizeof(cmd_t));
char *cmd_name = (char *)malloc(strlen(name) + 1);
This problem is reproducable with my code. Every time I switch to the newst revison I get problems and serial is not working anymore. When I switch back to 07.Jul.2016 I got no problems.
