Hello everyone,
I'm trying to fill in the stub functions in newlib and the SDK so that I can define custom I/O streams.
I thought I knew what was what but it seems I've missed something vital.
When I do a printf I don't see anything on the output, I've got my code here. the Printf call is writing to my output so I know something is working
what more is needed to make printf call write?
in my code I've added these lines to hopefully see some

Code:
int _write(int fd, void* buf, size_t cnt) { Printf("_WRITE %u:%s, %d\n\r"); if (fd == STDIN_FILENO) { return EOF; } if (fd == STDOUT_FILENO || fd == STDERR_FILENO) { for (size_t i = 0; i < cnt; i++) { Decode_Character(((char *)buf)[i]); } return cnt; } fd -= 2; if (PT_FilePool[fd] == NULL) return set_errno(EBADF); size_t ret = 0; FRESULT fr = f_write (PT_FilePool[fd], buf, cnt, &ret); if ( fr != FR_OK ) return fatfs_error(fr); return ret;}in my code I've added these lines to hopefully see some
Code:
stdio_init_all(); printf("Hello World!\n\r"); puts("Ready");Statistics: Posted by DarkElvenAngel — Tue Dec 10, 2024 12:36 am
