Hello, I have tried to re-activate my old QNAP TS209 NAS, but so far without success. The NAS system was broken (it did not boot any more) after I was trying to flash the QNAP recovery software. Therefore, I am trying to flash the original QNAP firmware using the serial header as described in the webpage from Martin Michlmayr https://cyrius.com/debian/orion/qnap/ts-209/uboot/
However, the TFTP file transfer starts and then always stalls at 12% of a 95 Mbyte file. The error is narrowed down to QNAP U-Boot since I have already tried to use different computers for the serial communications as well as different communication programs and TFTP servers. I have looked at the commands available from U-Boot. Resetting the environment variables with resetenv before starting tftp did not improve the result. Before trashing the entire NAS box, I wanted to ask on this list if somebody has an idea what else I could try to flash the firmware. I am not familiar with U-Boot, but willing to learn and to give it a try. QNAP TS209 is running on a Marvell board with U-Boot 1.1.1, Marvell version 1.11.2. Thank you. Greetings, Rainer
