RE: Instruction OCM
Actually there is no overlapping between IOCM and DDR. The IOCM region addre4sses are: PARAMETER C_BASEADDR = 0xc0a0 PARAMETER C_HIGHADDR = 0xc0a1 And the DDR addresses are: PARAMETER C_MEM0_BASEADDR = 0x PARAMETER C_MEM0_HIGHADDR = 0x0fff Furthermore, if such a conflict existed, the synthesizer would have identified it. -Original Message- From: Stephen Neuendorffer [mailto:[EMAIL PROTECTED] Sent: Monday, May 19, 2008 6:59 PM To: mojtaba; linuxppc-embedded@ozlabs.org Subject: RE: Instruction OCM The traps are down there in low memory. trap 700 is probably the one that deals with MMU exceptions.

RE: Instruction OCM
Thank you for your email. But what is the solution to that? I have seen this in a thesis: when using the OCM buses to connect memory, we can only use virtual memory as long as the virtual address is the same as the physical address, which is conceptually the same as using a system without MMU. Therefore porting Linux to a system based on an OCM memory system is not possible http://ce.et.tudelft.nl/publicationfiles/1367_700_thesis.pdf Is that right?

If instruction OCM is same as data OCM (I think it's so) then any MMU mapping is not applicable to this region at all as OCM controller decodes virtual addresses bypassing any MMU mappings. In your situation MMU maps virtual address of OCM to physical address containing some random data and CPU tries to execute it.

Booting Linux from an ACE File
Dear all, Could you please explain what happens exactly when Linux is booting from a compact flash? To my few knowledge, the Linux compressed image will be copied somewhere in memory, will be uncompressed and the control will jump to the beginning address of the Linux kernel. Is there any boot loader that copies the Linux compressed image to the memory? Where in memory does it put the Linux kernel? For example, if I have 2 DDRs in my hardware, in which of them it will be put the kernel? Can I set the kernel location in memory manually? Might be an stupid question but: Is it possible for the kernel to be half in BRAMS and half in DDR?

OCM instruction memory
Dear all, I have a problem with OCM instruction memory. When I create a simple hardware design without OCM instruction memory, I can easily run Linux on it. But, when I add an OCM instruction cache with the size 128K, the system freezes at this point: loaded at: 0040 004CE1A0 board data at: 004CC120 004CC19C relocated to: 00404050 004040CC zimage at: 00404E88 004CBE3E avail ram: 004CF000 1000 Linux/PPC load: console=ttyS0,9600 root=/dev/xsa2 Uncompressing Linux...done. Now booting the kernel I already test the memory and it's ok. I asked my pervious question about system ACE because of this problem. Actually I thought that the linux image might be copied to the OCM instruction memory. If the linux image is copied to the address zero which my DDR is mapped there, there should be no difference between the platform with OCM and without? Can you please help me on this issue?

RE: File system problem
Hi, Thank you all for your helps. Today I tried to make the file system again using buildroot. This time I included busybox to the packages for target system (Before that, I did not include the busybox). Surprisingly the system boot correctly. But, I do not want to use busybox. I already compiled coreutiles and I want to put them on my target system. After building the root file system I tried to replace those symbolic links to busybox(such as ls, cp, ...) with the real commands from coreutiles but I got this error. Freeing unused kernel memory: 76k init missing file opeKernel panic - not syncing: Attempted to kill init! rand Try `/bin/Rebooting in 180 seconds..sh --help' for more information.

This time the system freezes at this point. Freeing unused kernel memory: 76k init Hi Mojtaba, I just want to comment on your observation that the file size in /dev was zero. This is normal as the device files are 'special' since they are a mean of abstracting the interface to the kernel. I had to read the online book listed below before I could understand the inner workings of those special files. If you plan on interfacing your FPGA with the Linux Kernel, I suggest you read it too, as it is a very insightful book: http://lwn.net/Kernel/LDD3/ At this point, your system is not frozen, but your init script and configuration files are probably not all correctly set. You might need to read some documentation about buildroot to see what its init scripts are trying to do. You might be missing a library or symlink (I got that problem in my attempt to build the BusyBox root filesystem from scratch). One way to go at the problem is to pass the init=/bin/ash or something like that to your kernel at the boot prompt (you could even make some trivial 'hello world' program and pass it to the kernel as the init process). This way, you can dive right into a shell or your program and avoid init and its configuration. After some copying of required libraries in /lib (I'm using uClibc) and the creation of the required symbolic links, I got my Busybox root filesystem working on my ML-310 board. Good luck!
