Hi, I took the latest tree from linux/kernel/git/galak/powerpc.git (2.6.26-rc2), and the latest dtc from linux/kernel/git/galak/dtc.git. After compiling, I am having couple of questions. 1) Doesn't the latest dtc support /memreserve/ on the top before or after /dts-v1/? This used to work fine fo

Trying 10/HALF

Hi, After booting, my MPC8641 based board keeps printing "Trying 10/HALF" for ever. I am unable to use the Ethernet, even though there are interrupts occuring. Based on /proc/interrupts, both tx and rx interrupt count is increasing, and zero count for enet_error interrupt. I think this is c

Device node - How does kernel know about it

Hi, I am really interested in finding out how kernel knows about device nodes and how the whole thing work. This is as part of my debugging effort on 8641D based PowerPC board. * It all started with the problem of "not printing" any thing that comes from ramdisk (echo and printf statements), whil

Hi, I have a initrd image that I am trying to use on 8641D. When I mount it on a regular PC (using mount -o loop ), I can see all the required files in /dev directory. However, after loading the same into the target board, all the files in /dev is missing, making it not print any messages (as /

Hi, I am trying to boot kernel with initrd. However, it hangs in run_init_process("/sbin/init"). I went into the system calls to see what it is doing. As part of debugging, I ended up adding a printk statement in arch/powerpc/kernel/process.c:sys_execve() routine. Noticed that all the calls are

RE: Regarding MPC8641D

BTW... it is not true that core1 is idle when low memory offset mode is disabled. Taking core1 out of reset will enable core1 to start booting. These two are two different things. - Siva -Original Message- From: Siva Prasad Sent: Wednesday, December 05, 2007 5:06 PM To: 'linuxpp

Regarding MPC8641D

Hi, If you want to use SMP, do not enable low memory offset mode. That is only and only for AMP, not for SMP. All the exception vectors go into a different address range for core1, once you enable that, resulting in a need for entirely different copy of OS (be it Linux, or any other OS). You are

Hi, I am using 2.6.19 Linux on 8641D based system. I am using early printk's and it works fine until console_init() is executed. After that it does not, as the early printk's get disabled, which is fine. However, I don't see any prints after that at all, that are based on regular printk statement
