Browse code Fix bug in semihosting write function The return value from the SYS_WRITE semihosting operation is 0 if the call is successful or the number of bytes not written, if there is an error. The implementation of the write function in the semihosting driver treats the return value as the number of bytes written, which is wrong. This patch fixes it.

the call is successful or the number of bytes not written, if there
is an error. The implementation of the write function in the
semihosting driver treats the return value as the number of bytes
written, which is wrong. This patch fixes it.
