Forum Post: TI8148 can't load 1st stage UBOOT under UART

Hi, 

We've just made our board using the 8148, I'm able to see the CCCCC across the serial port, when I try to load the .uart file over Xmodem, I see on the trace that the CCC's are still being sent, but the file isn't sending. 

In the instructions it says to hit the reset button on the EVM...which reset do I need to assert to get the download to start on our board?

Thanks

Dave
