YAMONâ„¢ is the ROM monitor used on MIPS Technologies' development boards.

An example of YAMON boot log on a MIPS Malta Board with a 24Kc core:


YAMON ROM Monitor, Revision 02.06. Copyright (c) 1999-2004 MIPS Technologies, Inc. - All Rights Reserved.

For a list of available commands, type 'help'.

Compilation time = Mar 23 2004 16:50:44 Board type/revision = 0x02 (Malta) / 0x00 Core board type/revision = 0x07 (CoreFPGA-2) / 0x00 System controller/revision = MIPS SOC-it 101 OCP / 1.3 SDR-FW-1:1 FPGA revision = 0x0001 MAC address = 00.d0.a0.00.04.2b Board S/N = 0000000819 PCI bus frequency = 33.33 MHz Processor Company ID/options = 0x01 (MIPS Technologies, Inc.) / 0x00 Processor ID/revision = 0x93 (MIPS 24Kc) / 0x60 Endianness = Little CPU/Bus frequency = 25 MHz / 25 MHz Flash memory size = 4 MByte SDRAM size = 64 MByte First free SDRAM address = 0x800b3860

An srec kernel image can be loaded in YAMON as follows:

load tftfp://<tftp server name>/<srec file in /tftpboot>

for example, if I have a vmlinux.srec in /tftpboot on 10.0.0.139, then:

load tftp://10.0.0.139/vmlinux.srec
