高手看过来!2650BU怎么用JIAG线救回来啊！在线等啊！
本帖最后由 wuhandavid 于 2010-7-11 18:01 编辑我的2650BU双U口的老猫！按照这个帖子的方法在做https://www.chinadsl.net/viewthread.php?tid=37615&highlight=JTAG，最后在写入CFE时，老是不成功！出现如下信息！望高手指点下是什么原因！

Optional Switches
-----------------
/noreset ........... prevent Issuing EJTAG CPU reset
/noemw ............. prevent Enabling Memory Writes
/nocwd ............. prevent Clearing CPU Watchdog Timer
/nobreak ........... prevent Issuing Debug Mode JTAGBRK
/noerase ........... prevent Forced Erase before Flashing
/notimestamp ....... prevent Timestamping of Backups
/dma ............... force use of DMA routines
/nodma ............. force use of PRACC routines (No DMA)
/ejtag0............. with low speed ejtag access cycle
/waitbrk............ wait until CPU enter debug mode
/pracc0 ............ with safe PRACC access routine(Areg+Dreg)
/initcpu............ load CPU configuration code
/nompi.............. skip autodect flash base address with MPI Reg
/revendian.......... reverse chip endian
/window:XXXXXXXX ... custom flash window base&probe address(in HEX)
/start:XXXXXXXX .... custom start location (in HEX)
/length:XXXXXXXX ... custom length (in HEX)
/verbose............ scrolling display of data
/skipdetect ........ skip auto detection of CPU Chip ID
/instrlen:XX ....... set CPU instruction length manually
/wiggler ........... use wiggler cable
/nocfi ............. disable CFI query flash geometry
/forcenoflip ....... force not flipping CFI queried flash geometry
/forceflip ......... force flipping CFI queried flash geometry
/bypass ............ unlock Spansion bypass mode & disable polling
/forcealign......... force erase address align with block boundary
/erasechip.......... erase whole chip, only work with -probeonly
/clearppb........... erase Spansion PPB,only work with -probeonly
/showppb ........... show flash sector protection status
only work with -probeonly
/port:XXX........... customize parallel port(default XXX is 378)
only work in Windows version
/fc:XX = Manual Flash Chip Selection(disable CFI and ID auto match
use 'brjtag /showflashlist' show build-in flash list
NOTES: *) '-backup:', '-flash:' and '-erase:', the source filename must exist
as follows: CFE.BIN, NVRAM.BIN, KERNEL.BIN, WHOLEFLASH.BIN or
CUSTOM.BIN, BSP.BIN, TFE.BIN(64KB or 1x bottom Sector length CFE)
*) Brjtag is only able to handle X16 Parallel Flash chip, The CPU
native set length need 32Bit.
*) Brjtag uses CFI command set to automaticlly detect flash chip
parameters. If you have difficulty auto-detecting flash with CFI,
'/nocfi' convert to orginal flash detection method. brjtag then use
detected flash ID quary parameters from build-in flash list.
particularly, you can use '/fc:XX' manually specify flash ID.
'brjtag /showflashlist' can print build-in flash list
*) '/forcenoflip' and '/forceflip' can help on some AMD type flash
detecting sector structure correctly if CFI uses.
'brjtag -probeonly /verbose' debug flash detection
*) If you have difficulty with the older bcm47xx chips or when no CFE
is currently active/operational you may want to try both the
/noreset and /nobreak command line options together.Some bcm47xx
chips *may* always require both these options to function properly.
*) When using this utility, usually it is best to type the command line
out, then plug in the router, and then hit <ENTER> quickly to avoid
the CPUs watchdog interfering with the EJTAG operations.
*) /bypass - enables Unlock bypass command for some AMD/Spansion type
flashes, it also disables polling
*) /initcpu allow load config code to initialize the CPU. This may help
BCM6358 prevent from some address non-accessable.
*) '-probeonly /window:xxxxxxxx /erasechip' allow choose a workable
sector address to erase whole chip. This may help on a bricked box
with bad CFE
*) /forcealign - enable erase sectors if the operation window is not
aligned with sector boundary. It's risky! but can help erase some
box NVRAM area whose sector size is larger than NVRAM definition
*) /ejtag0 - enable 20ns delay behind each jtag shift cycle. This wish
to increase LPT port compatiability for some high clcok PC
***************************************************************************
* Flashing the KERNEL or WHOLEFLASH will take a very long time using JTAG *
* via this utility.You are better off flashing the CFE & NVRAM files *
* & then using the normal TFTP method to flash the KERNEL via ethernet. *

C:\JIAG> JTAG有个图形界面的软件、、、在ADSL相关区里、、
https://www.chinadsl.net/thread-43693-1-2.html
cfe和软件放在同一个目录、、、CFE名字改成CFE128.BIN 求知道的高人在指点一下，看上面信息到底是我那没有设置对或其他原因 芯片没认出来，你把连接线尽量的缩短最好在10CM内，再试试！ 芯片没认出来，你把连接线尽量的缩短最好在10CM内，再试试！

连接线是指从板子上引出的线，还是指JIAG线在弄短点呢？ 芯片没认出来，你把连接线尽量的缩短最好在10CM内，再试试！

连接线是指从板子上引出的线，还是指JIAG线在弄短点呢？ 是指JATG口到电脑并口的线 忘了，你用这个两个版本的BRJTAG试试看 谢谢楼上的兄弟，问题解决了！关键的命令被搞错了，写入CFE的命令C:\JIAG>brjtag -flash: cfe在冒号后面没有空格！就是这搞了2天才搞定 看晕了，不知道咋弄了。
