Wolfgang,

I agree we need to fix the UART. It is only one unit that has the problem and I am trying to make it work for a deadline. I will try the suggestions.

By the way it is a PXA based board.

Thanks, Michael

Which sort of processor is this? On 8xx there is CONFIG_8xx_CONS_NONE, on other boards you can probably do the same using CONFIG_SILENT_CONSOLE and/or CFG_CONSOLE_INFO_QUIET

trouble with my serial debug port and I can not get past the code that tries to read off the port.

I don;t think it is wise to ignore easy problems and try to go on running into more complicated ones. Better solve problems step by step. Don't continue if you cannot initialize a simple device like an UART. Just my $0.02.

Best regards,

Dear Wolf Denk: My problem of ld scripts has been solved!I make two mistake. 1. The enviroment file is common/env_common.o not common/enviroment.o 2. The arm seem can't use ppcenv but text. I use the scripts below and put the enviroment parameter in right room. Thanks! .SECTIONS { . = 0x00000000; . = ALIGN(4); .text : { cpu/arm720t/start.o (.text) *(.text) }

. = ALIGN(0x1000); .rodata : { *(.rodata) }

. = ALIGN(4); .data : { *(.data) }

. = ALIGN(4); .got : { *(.got) }

armboot_end_data = .;

. = ALIGN(4); .bss : { *(.bss) }

. = ALIGN(4);

.text : { . = 0x10000; common/env_common.o }

armboot_end = .; }

Dear Joe,

No, it aint. It's just hidden now.

two mistake. 1. The enviroment file is common/env_common.o not common/enviroment.o

Wrong. common/env_common.o contains code and the (constant, read-only) DEFAULT environment.

The environment itself is represented by common/enviroment.o

2. The arm seem can't use ppcenv but text.

Wrong again. Some ARM boards use it, for example the TRAB board configuration. You will have to add your board to the list #defined in common/enviroment.c though.

I use the scripts below and put the enviroment

parameter in right room. Thanks!

This does NOT do what you think it does. Did you ever try "saveenv" in U-Boot? It should show you pretty clearly that your configuration is broken.

Best regards,

Wolfgang Denk

Yes,After E-mail to you and I find theses wrong!

For the future: please test your code _before_ posting.

But,It's really that we can't use ppcenv althogh I

defined my board config in the common/environment.c.

You must be doing something wrong there. It works for everybody else.

Now,I use this way to avoid it.
Calculate the u-boot.bin's length.
define the env offset > it.
so it's ok! 

Are you sure you know what you are doing?
