2008-06-20 07:34:35     Uboot1.1.6 issue

Hi,

 

We are using Blackfin BF561 based embedded hardware.

 

In this hardware we don't have ethernet.But we have UART connectivity and using the PC is connected using Teraterm.

 

For this hardware we created a Uboot image using  UBoot 1.1.6 version and downloaded the same.

 

On board reset  We could able to see the U-boot getting booted up, using tera term window.

 

Once it got booted up, the teraterm is not responding for key input.

 

i.e. the commands from the keyboard is not getting detected , meaning whatever we type in keyboard is not getting reflected in tera term window.

 

Please help me to fix this issue. We are getting the following message on Teraterm

please remove the "Support:" line from your custom board.  it isnt a board we support so you shouldnt be displaying our website.

 

you should also update to 2008R1 as board porting is much easier.

 

specifically for your UART, you should verify that the your UART hardware lines are properly hooked up.  it takes 1 pin to transmit, but it takes 1 pin to receive.  otherwise, you can add some debug code to print out all the UART registers and see what their status is, or hook up jtag and monitor it.
