hi,
i did add the UART2 in the serial multi infrastructure at the end of my serial.c. i have also configured GPIO registers for enabling UART2 Tx and Rx lines. As I understand, these lines are also multiplexed with the boot strap lines of the PowerPC 440EP. Will this create any issue in the performance? As I already mentioned I have enabled #define CONFIG_UART2_CONSOLE and
#define UART2_BASE CFG_PERIPHERAL_BASE + 0x500
You have mentioned to enable the UART2 as default stdin and stdout...where do I enable that??
Thanks & Regards, Prathika R

i have ported u-boot this way to my board with few changes in the u-boot source code and the board is up and i have tested stand alone application execution also.
So you did a "real" board port to your custom board? Or did you "just" change the yosemite files?
Now as my requirement is that my console should be on UART2 as my UART0 and UART1 are coming out as RS 422 lines and only UART2 is RS232. I did some patch up work on UART0 lines and tested my u-boot porting.
Ah, I though you wanted the console on UART1. Ok, then my solution does not work for you.
I added a line
#define UART2_BASE CFG_PERIPHERAL_BASE + 0x500
I have now changed as below and I commented checking for #define UART0_CONSOLE and #define UART1_CONSOLE:
#define UARTBASE UART2_BASE
Is this OK??
Best would be to add the 3rd UART (UART2) to the SERIAL_MULTI infrastructure (see end of serial.c) and use this device as "stdin/stdout/.." in your default environment.
Best regards, Stefan
