riscwatch shows up core status UNKNOWN for 970mp ppc processor

[anil kumar]

Hello
I am newbie to RISCWatch and debugging using JTAG interface .I want to debug
Linux Kernel on target board
using jtag interface provided on board.

To  debug 970MP dual core ppc processor on traget board, I installed
RISCWatch software on my window host.

My Setup:
----------
   Host <--(over ethernet)--> RISCWatch 13H6423 <--(jtag interface)--> 970MP
Processor

I am able to detect two core on target 970MP processor but it shows both
cores as `UNKNOWN` . I have no idea,
why riscwatch shows up status of both cores as UNKNOWN?

I would like to mention:
-------------------------
1) After attaching JTAG cable & switching on riscwatch box, powered cycle
was done on the target board
   and restart RISCWatch. But still core status is shown `UNKNOWN`
2) For PVR value 0x00440101, I used `REV = 1' in rwppc.env file. Correct us
if I am wrong.
3) I am able to ping RISCWatch 13H6423 from host system.
4) When I reset target board, target status changes from "UNKNOWN to HALTED"
and "HALTED to UNKNOWN"

I noticed that PVR register value is 0x00440101. I am not sure if this
confirms that revision of the processor(970mp) is 1.


Please find the rwppc.env file (C:\Program Files\RISCWatch\rwppc.env) that I
configured:
----------------------------------------------------------------------------------------
PROC = 970MP
REV =  1
TARGET_TYPE = jtag_eth
TARGET_NAME = 192.168.10.5
RWPPC_DIR = .
SEARCH_PATH = .
LOG_FILE_DIR = .
SAVE_LAYOUT = no
PRD_FILE = rwppc.prd
