Change mnemonic SEMIHOST_FILE_MODE_CREATE with mnemonic SEMIHOST_FILE_MODE_UPDATE. The bit referred to by this mnemonic is for the semi-hosting open mode code the equivalent of the + in the ISO C fopen mode terminology. This allows to select the so called update mode for which both read and write are allowed on the open file. The mnemonic SEMIHOST_FILE_MODE_UPDATE is more in line with the ISO C fopen mode terminology. A description of the ISO C fopen modes can be found here : http://pubs.opengroup.org/onlinepubs/009695399/functions/fopen.html.
