嵌入式Mips平台YAMON烧写flash

1.打开tftp：tftpd32.exe(用来传输烧写的文件)

2.打开串口

3.启动目标板，一直按ESC键或者0，使之进入yamon命令行下

4、在yamon命令行下初始化网络配置。
YAMON> net init                        (查看网络设置)
Ethernet driver for EM86XX (v1.0)
(MAC 00:16:e8:ee:d6:ee, tx_desc/rx_desc = 16/32)
em86xx_eth::open(em86xx_eth) - Full-duplex mode
em86xx_eth::open(em86xx_eth) - 100 Mbit/s
em86xx_eth ethernet start
ipaddr:     10.0.0.20
subnetmask: 255.255.255.0
gateway:    10.0.0.1

YAMON> setxenv y.ipaddr "192.168.73.244"(设置IP)
Original value: "10.0.0.20", New value: "192.168.73.244"
Updating XENV block at 0x48000000.
.
XENV verification OK.

YAMON> setxenv y.gateway "192.168.73.1" (设置网关)
Original value: "10.0.0.1", New value: "192.168.73.1"
Updating XENV block at 0x48000000.
.
XENV verification OK.

YAMON> net init                         (查看网络设置)
net have been initialized
ipaddr:     192.168.73.244
subnetmask: 255.255.255.0
gateway:    192.168.73.1

3、烧写zboot
3.1、按下面命令通过tftp下载目标代码到目标板

YAMON> load -b tftp://192.168.0.37/zboot2.bin 0xb0100000    (将文件下载至以0xb0100000为起始地址的空间)
About to load tftp://192.168.0.83/zboot2.bin
Press Ctrl-C to break
.....

Start = 0xb0100000, range = (0xb0100000,0xb012f193), format = BINARY
Length = 0x2f194 (192916)
Checksum = 0x86457147

3.2、按下面命令烧写目标代码到目标板
YAMON> pflash write 0x0 0xb0100000 0x2f194       (将起始地址为0xb0100000，长度为0x2f194的文件烧写到以0x0为起始地址的空间)
  0x00000000 - 0x0002ffff will be erased
  0x00000000 - 0x0002f193 will be written

Start = 0xb0100000, range = (0xb0100000,0xb01303ff), format = BINARY
Length = 0x30400 (197632)
Checksum = 0xd5974852

4.2、按下面命令烧写目标代码到目标板
YAMON> pflash write 0x40000 0xb0100000 0x30400(将起始地址为0xb0100000，长度为0x30400的文件烧写到以0x0为起始地址的空间)
  0x00040000 - 0x0007ffff will be erased
  0x00040000 - 0x000703ff will be written
