Hi all,
Im working with a router WRT320N with broadcom 4716 processor, mips32
74k core. I have no information to speak of on this board, I am used to
an ir length of 5 or 8 for broadcom CPU's, Openocd complains about 5 or
8, with an error a bit 8. I have tried detection with a few other
applications, and they both tell me IR length is 32.
the IDCODE seems to be detected correctly, but the IMPCODE is always
different, as a matter of fact, if I change the define for IDCODE to
IMPCODE, I still get IDCODE, its as if the board is locked, and will
only give up IDCODE.
Q. How can I correctly identify the IR length, etc ? knowing I have no
access to documentation.
Any help or advice/feedback appr.

Hi Tornado,
I want to using Openocd to debug a board which has an CPU of Broadcom
BCM53001 with 74K core. I meet the same problem as you. When I google
it, I found you had added bcm4716 support to Tjtag project. How do you
fix it?
Thanks!
