2008-05-13 22:38:35     Expand the trace buffer

Hi,all

  I'm trying to expand the trace buffer base the 2007r1.1-rc3 kernel

source. I refer to the svn revision 3292 and 3401. But the kernel can't

get the command line from the u-boot when booting up. I'm still using

the old u-boot-1.1.6. Is't need to change u-boot?

I set the kernel command line in the menuconfig. so the kernel can boot

up with right args though it can't catch from u-boot. The kernel crash in

setting the mac. And the Hardware Trace did expand to 2k.

  Should any other svn change need to added?

regards,

roy

we really dont support back porting of code, especially ones that touch so much core architecture code

 

just upgrade to 2008R1 and use something that is supported and tested

Hi,Mike

  I fixed the kernel command line problem reference to this forums. Now It can bootup

with Hardware Trace expand to 2k. but the bfinmac can't use L1 memmory. That's like the

bug "[#3399] BF537 MAC Doesn't like to not have enough L1 (crashes kernel)".

  I have test the 2008R1 kernel. It does not have that bug. How did you fix this? Is there

any different between 2007 and 2008 source at L1 memmory using?

regards,

roy

disable L1 support in the MAC driver kernel config then.  or use 2008R1.
