Hi there,

I have iduino Yun and its network (LAN and WLAN) are not working since I got it from ebay. I tried to flash using TFTP but it does not work bacause of LAN failure.
Does anyone knows how can I flash it using UART or RS-232 - USB what ever?

PS: When I ping it over LAN or wifi it respond only on 2-3 of 100 pings. Something is not ok. Its brand new but does not work.

Thanks.

Only buy from trusted sellers on ebay. Poor packaging will cause damage to those boards. I had those experiences.

Yes only buy from trusted buyers, One of my friend told me he lost his money contacted with bad seller, Ebay is good and check seller ratings and choose high rate sellers.

The most common cause of serial port communication problems is incorrect communication parameter settings. To operate correctly it is essential that both devices are set up with the same communication parameters, which includes baud rate, parity, number of data bits, and number of stop bits. thank You. .
