Hi:
Thanks for reply, i solved this problem earlier, i reallocate the newest rootfs from ti-sdk-am335x-evm-07.00.00.00 and everything is fine. But i have another problem now, i follow the tutorial and would build file from QtCreator then pass to my target board, but my qt creator(3.1.2) seems to no compatible with the library from SDK, any suggestions for me? thanks in advance.
