@jlaitine I uploaded a patch to solve the ioctl problem https://github.com/apache/nuttx/pull/16029/commits/f6b28e91af9fff70ce99fd387dd49f8c2fb93f58. And a modification was made in reader_writer function in the hello app: ``` /* NOTE: FIONREAD is broken. remove the following line to * experience this */ //bytes_to_read = 1; if (bytes_available > 0) { memset(buffer, 0, sizeof(buffer)); nread = 0; } if (retval == 0 && bytes_available >= bytes_to_read) { int n = 0; do { n = read(ttyacm_fd, buffer + n, bytes_to_read - nread); nread += n; } while (nread < bytes_to_read); printf("read %d characters : %s\n", nread, buffer); } write(ttyacm_fd, hello_world, sizeof(hello_world)); usleep(100000); ``` -- This is an automated message from the Apache Git Service.
