Hi Ramkumar,
XMD can definitely be used to help debug a kernel. I use it to dump registers and to dump memory. I'm not sure on the TLB entries yet but will check into it. I'm sure that XMD does not handle any virtual address to physical conversions. I use it to dump the log buff sometimes when the kernel doesn't come up. You may need to do a RST and then you need to use the physical address rather than the virtual address (Address - 0xC0000000). You can do a help in XMD. Thanks, John ________________________________ From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Ramkumar J Sent: Wednesday, March 12, 2008 9:15 AM To: [email protected] Subject: XMD to debug Linux kernel 2.6 Hi All, I need to dump the TLB entries, i-cache and d-cache entries on a ML-403 board ( I use a PowerPc based design) using the Xilinx Parallel-4 Cable. When I download the zImage.elf using dow command on XMD, I m not able to access the TLB and cache address special memory mappings as displayed by the XMD. I suspect that XMD only allows the dump for sections inside the elf file. If its true, then how to access the sections of kernel. Could XMD be used to debug a linux kernel by dumping the registers, TLBs, cache entries,etc. Am I missing anything. Any pointers would be very helpful. Thanks and Regards, Ramkumar
