2008-02-29 10:28:04     2008R1-RC2 cannot work on BF527 with 2 pics 32MB SDRAM (32M x8)

C.C Lu (TAIWAN)

Message: 51903    Hi All,

 

My BF527 (not BF527c) uses two pics of 32MB SDRAM (32M x 8).

When I downloads uclinux image in u-boot, then boots the image.

It stops in "Starting Kernel at = 14c000".

 

How to fix this problem?

Message: 51972    You may try to enable early printk:

http://docs.blackfin.uclinux.org/doku.php?id=post_mortem#early_printk_compiled_into_the_kernel

 

As Michael asked, what is your kernel command line? Sometimes if the console is not set correctly, the boot message will not be displayed.

Message: 51973    I enable 'early printk' and set bootargs 'root=/dev/mtdblock0 rw earlyprintk=serial,uart0,57600 console=tty0 console=ttyBF0,57600'.

But it stops in 'Starting Kernel at = 14c000' when I bootm image.

What is mean of kernel command line?

The uImage-SVN-bf527-ezkit image is still not work.

The Silicon of BF527 Ezkit is Rev 0.0. My BF527 board is Rev 0.1.

When I choice silicon rev 0.1 in menuconfig, it has compiling error message of "ccl: error: -mcpu=bf527-0.1 has invalid silicon revision."

My board uses 2 pics 32Mx8 SDRAM instead of 1 pic 32Mx16 SDRAM of BF527-ezkit.

Do modify some settings of this collocation in the kernel or menuconfig?

  It works fine. I make a mistake.

My BF527 board use uart0 for rs-232, not uart1.

I am modified U-Boot to uart0, but I don't enable uart0 driver in uClinux.

Sorry.
