Jtagging Relook 400s

[weirdo]

I'm trying to jtag a Relook 400S but sofar without success.
The erro I get is the following

relook400s (PAL) board initiation
Flash info : Unknown Unknown
Flash recognize failed
Retry (0x0, 0x0)

Does this mean my flash is fecked?

[mate]

what is jtag?
to flash these units you should be using flash tools

[weirdo]

jtag is a last measure
If you can't connect with telnet,serial or usb then jtag is the only option left.

[mate]

put it in a box and send it to sciteq in Perth and get them to have a look at it.
maybe give 'em a call 1st

[weirdo]

Yeah thanks mate, that will be my last resort.
I'll have a go myself first. Just not too successful sofar as the jtag doesn't recognize the flash.
I've double checked my cable and tried two different pc's sofar (both XP, haven't tried W98) but both have the same result.
I'm afraid the flash chip might be stuffed.
Not sure if they can be replaced?

They are dead easy to jtag. Ive done quite a few with my old win98 laptop. What type of cable are you using?

I made my own cwispy
Connections from db25 PC Parallel port to Relook400 JTAG Pins (CN4):
Code:

JTAG Connector:

Signal Pin Pin Signal

TDO 1 2 N/C

TDI 3 4 TRST

N/C 5 6 VCCS

TCK 7 8 N/C

TMS 9 10 N/C

HALT 11 12 N/C

N/C 13 14 KEY

N/C 15 16 GND



Cable from PC to JTAG connector:

db25 . . decoder

2 --> 100 ohms --> 11 ( Halt)

3 --> 100 ohms --> 9 ( Tms )

4 --> 100 ohms --> 7 ( Tck )

5 --> 100 ohms --> 3 ( Tdi )

11 --> 100 ohms --> 1 ( Tdo )

25 ------------------ 16 ( Ground)


No longer than 10-12 cm
I notice a different reply when reversing the header on the pins.
Also odd thing is eventhough the flash is not recognized I can press the On/Off button and OK button at the same time and the clock will appear on the display.
Normally when I switch the powerswitch on the whole display lights up

This is the jtag method I followed
1. Create a folder 'c:\jtag'

2. Download: ftp://dev.dgstation.co.kr/pub/relook...tag_0.1.tar.gz

3. From this package, copy 'Relook400s_PAL_Jtag_0.1.exe' into 'c:\jtag'

4. Download: 'porttalk22.zip' from

5. From this package, copy 'AllowIo.exe' into 'c:\jtag'

6. And 'porttalk.sys' into 'windows\system32\drivers'

7. Double-click on 'porttalk.reg' to register porttalk.

8. Open an cmd Window (Startmenu, run... cmd [enter])

9. Go to folder 'c:\jtag' (cd c:\jtag)

10. Type: AllowIo.exe /a Relook400s_PAL_Jtag_0.1.exe

Are you sure that its not just the wrong mID set on the box? What happened that you need to jtag in the first place? Did the power go out during a flash, the computer turned off... etc etc.

I wish. Purely operator f*ckup mate
Shorted the HD contacts on the powersupply heatsink.

[cwispy]

Ouch. Sounds like you have let the smoke out of something else then. Probably time to price a replacement main board.

[weirdo]

Thanks cwispy.
Sent Sciteq an email enquiry.
Let's hope it's not too exy.

[vk6xlr]

While trying many images for my 400s, I managed to get the same symptoms as weirdo.
Used these instructions and files. Worked a treat.

Only 1 file to run and does mutants too

Good piece of info. fixed my "initiating" problem. Total cost approx. $5.00

[weirdo]

Great to hear you were succesfull in jtagging your unit jamisiah
