Hugebird 你好，我的HG227改CFE变砖了，用2.0.5版本的写入CFE，识别到CPU是BCM5354 REV 03 ，识别不到闪存，实际是S29GL128P11TF101,于是手动指定/FC:88参数，可以写入，但始终提示：
DMA Read(x2) Addr = 1c000a6eData = (00000000)ERROR ON READ
DMA Read(x2) Addr = 1c000a6eData = (00000000)ERROR ON READ
写入完成后也不能启动，请帮我看一下怎么解决，谢谢！

另外我用的是自制的简易并口JTAG线，线长只有15CM，接台式电脑原生并口。
这个重要888
运行BRJTAG2.0.5时会提示“应用程序错误”见附图。
1.6r 支持了
S29GL128P10 留爪
谢谢你,辛苦了 :)

如果你的6368设备有JTAG接口，而又没接错的话，命令应该是和6358的没什么区别的。。
你用的是LPT线？那cab ...
我用的是usb转jtag线，FT2232d芯片，故采用cable：1参数。现将实际出现信息如下文。共采用2种方式，方式1，不使用skipdetect参数；方式2，带skipdetect参数。

hugebird 老大，请教：JTAG刷机成功，TTL下刷RG100A-AA电信原版也成功，可以进入WEB登陆界面，但超级密码失效（由TTL下用CAT查看PSI.XML文件所得），怀疑此密码未初始化到FLASH中，是不是无法写入电信固件所需的PSI区中？另刷2760U1.04可用，谢谢了

hi!
can you add support storlink sl3516 based on FA526 core (CS351X) or give JTAG instructions for...
sl3516 is an arm9 soc, brjtag currently have no plan to support arm core.
you can try openocd
回复 pttt 的帖子
bcm5354有可能flash采用是8位的数据位宽，试一下加/wx8开关，是否可以识别，
如果已经完全清空了flash，那么再加/initcpu开关
