Maybe it's the wrong address after all. Try to run "nm" on the vmlinux binary (should be gzipped in /boot) and check for all occurences of log_buf (and __log_buf). 0xc0000000 is the "start of physical memory" in Linux. Since your SoC starts ram at 0x80000000, all you need to do is replace the c with an 8. Alex -- To unsubscribe, e-mail: [email protected] To contact the owner, e-mail: [email protected]
