F5D7231改造项目!

macafee

准备动手改造F5D7231-4板,现板卡元件如下:
FLASH:MX29LV160C
RAM:EM638165TS
DSP:BCM4712
SWITCH:ADM6996L
改造目标:
1.扩大FLASH到4M,8M的从PDF来看需要特殊布线(估计板子不支持)
2.扩大RAM到16M以上,此板最大只支持64M
所需元件:
FLASH:MX29LV320C
RAM:太多,不列了!
此贴欢迎所有F5D7231拥有者参与,但是请不要灌水!否则封禁1周处理!

FLASH哪有卖？价钱多少？如果成本和4M的板子差不多还不如直接买块4M的

macafee

flash可以去拆旧的,也可以去买新的,只要能搞到就行!

macafee

RAM拆到一片,从PLEXTOR PREIUM刻录机尸体上拆了片8M RAM,FLASH暂时还没拆到!

macafee

换好RAM了,不过还是只认8M,估计要修改NVRAM,cfj麻烦你TELNET进你的板子,执行
nvram get sdram_init返回多少

macafee

另外把nvram show全部贴出来吧!

cjf

不懂怎么做

macafee

telnet 板子IP
用户名:root/密码问你自己
然后执行nvram show
贴出来就行了!

cjf

不懂怎么切长条的，只能一页页的贴了

macafee

sdram_init=0x0419
奇怪了.........怎么也会是0419........

macafee

还是不成功........搞不懂了......怎么改都只认8M......对比图片缺下拉电阻,焊了,一样不认.......奇怪.莫非板子缺少地址线或者数据线????

心想事成

是不是没内存焊好

太美你这个也是8M RAM的?
