Fixes issue #1562 reported by @justbuchanan. When building code with GCC-ARM / newlib, attempting to use the b (binary) mode in a fopen() call would fail. newlib would parse this option and pass it down to the LocalFileSystem open call which didn't like the unexpected O_BINARY flag in openmode. The openmode_to_posix() function in retarget.cpp would never set the O_BINARY flag for the other toolchains but for GCC it would just pass down whatever newlib placed there. This commit masks out the O_BINARY bit so that it never gets passed down to the file system drivers, just as occurs for the other supported toolchains. Test case: FILE *fp = fopen("/local/out.txt", "rb"); I tested that code on mbed LPC1768 and LPC11U24 boards while using GCC_ARM as the toolchain. It failed on both platforms previous to this change and succeeded there after. |
