Supports put/get > operations. Tested against tftp(d)-hpa. barebox uses POSIX file interface for working with tftp. We have to provide these basic functions (see fs/tftp.c): static struct fs_driver_d tftp_driver = { .open = tftp_open, .read = tftp_read, .write = tftp_write, .close = tftp_close, /* Other functions for unlink, truncate, mkdir, rmdir, stat, opendir, lseek, create are not so important. */ }; So **fs/tftp.c code is driven** by user code that uses file interface for accessing to the files on tftp-server. AFAI understand picotcp tftp support uses event-driven interface so **user code is driven** by picotcp tftp support code. How we can use picotcp tftp support for realization of POSIX file interface? -- Best regards, Antony Pavlov _______________________________________________ barebox mailing list barebox@xxxxxxxxxxxxxxxxxxx http://lists.infradead.org/mailman/listinfo/barebox
