The following is a complete boot log: Serial Number = WAC6200032 MAC Address 1= 00:0D:5D:00:eb:6f Kernel Image Length = 0x695000, CRC = 0xd2ee6a23 Loading Linux ...... Downloading from ethernet, ^C to abort and restart pmonitor sendRRQ vmlinux.bin load linux length 0x34408a Checking CRC on downloaded RAM image / CRC Check passed Image Started At Address 0x80020000. Image Length = 3424394 (0x34408a). Exception! EPC=80056eb4 CAUSE=30000008(TLBL) 80056eb4 8ce4000c lw a0,12(a3) # 0xc All messages before the exception are from PMON. I am booting via TFTP. I also tried writing the kernel to flash and booting from that, but that fails identically. I checked the other serial port on the device, but it is not showing any kernel messages either. The normal boot console is ttyS1. I tried setting the kernel parameters and the default parameters (from the kernel build config) to "console=ttyS1", but that made no difference. Regardless, I would think that the kernel knows where to send messages because I am seeing the exception dump on ttyS1. Further, the exception gets printed immediately after "Image Length = 3424394 (0x34408a)." The exception happens so soon that I doubt that the kernel does very much beforehand. Thanks
