Can you retry > with setting the baudrate to 115200 (-b 115200 IIRC). Doesn't change anything. In fact the tty is already configured for 115200 Baud. And I would expect that on a mismatch it wouldn't always die just after the header is uploaded. Just noticed that my binary.0 was corrupted as I extraced it from a nand dump that also included the oob area ...

This is still not explained. I would have expected that this select doesn't do anything noticable on the remote end. > >When booting from nand (as shipped by Netgear) the output starts with: > > You need to set boot source byte to UART (0x52 IIRC). Otherwise the NAND Just for the log: UART = 0x69.
