question about jtag using FT232H board #1

Open raghur opened 6 years ago

raghur commented 6 years ago

I saw the guide in chinese for FT2232 chip JTAG howto in this repo.

I have a FT232 board which is also a JTAG/serial/i2c/spi board - my question is will the code work with that too? My router has a BCM4716 (Belkin F7d7301 model)

I've been working on my old WRT54Gv2 router, and have the following: 0403:6010 Future Technology Devices International, Ltd FT2232C/D/H Dual UART/FIFO IC

Sipeed JTAG/TTL USB Adapter

./brjtag -backup:cfe /cable:1

On zjtag, the device/cable identification numbers are different.

./brjtag -backup:cfe /cable:5

Although brjtag/zjtag compiled fine after fixing their Makefile here, all I see is a hang with only printing the title of their program and what looks like a hanged USB activity/calls when using strace. Power light constantly flashing, so I might have shorted the pins via misleading advice on the DD-WRT forums, just prior to more reliable advice being posted not to short the pins. Might have used a kernel-2.6 on this device too, for which may have been subsequently pulled/removed, with mandating kernel-2.4 version only for wrt54g devices. Anyways, your post is a long time ago, and might help somebody crazily hacking an old router.
