U-boot on Avila GW2355 platform : UART not working

Hi,

Has anybody done the u-boot porting on Avila platforms. I have GW2355, which is based on IXP425 CPU.

I have used the existing IXDP425 support from the u-boot, and could get the console messages till the prompt. But the problem is I could not write anything in the console. I could see that the serial_getc() is looping around to get a character in the UART receive buffer. Since the "data ready bit" is not set, the loop is like a forever type.

Any idea on this matter ?.

Thanks in advance.

Regards,
Mahesh.

Mahesh,

I am not aware of the GW2355 and if it was a custom design since Gateworks does do custom boards. For their current "retail" offerings I had posted a patch a few months ago:

Hi Ranjit,

Could you resend your patch rebase on the current tree?

and create a board specific file for Avila not a hack in ixdp425 board.

Best Regards,
J.

Jean-Christophe,

1. Do you want the patch against the Xscale custodian tree or the mainline ?

2. Do you want me to create a separate directory under board/ ?
