    TECHNICAL SECTION ABOUT JTAG FOR NEWBIES

    Hello all friends ,First I wanna say "Thank You So Much" to Sir Masood and Sir Cogil who allow to make this section.Don't think about me bcoz. I'm not a superior in this JTag , as a great A student in this field.However I'll help u guys as much as I can.

    This topic is totally about JTag section.U can discuss about JTag'ing and flash programming in here , leran if u don't know something , share ur knowledge , collects ur experimental then to become a JTag's programmer from RDI.And help again other friends who is in ur position when u first visit here in RDI.How nice this is if we can stay like this in our life?

    Dear Sir Boknoy , Sir I2E , Sir Kevo , Sir Masood , Sir Cogil and other jtag's masters Plz. join with us and give us ur great technic about JTag.Hope all friends will co-operation with us.


    Best wishes to all.
    Yan Naing.

    Re: TECHNICAL SECTION ABOUT JTAG FOR NEWBIES

    INTRODUCING


    ##THIS IS VERY SENSITIVE ISSUE TO DO IT YOURSELF BEFORE U DON'T KNOW ANYTHING ABOUT THIS.AND IT'S REMAIN VERY DANGEROUS TOOL WHILE U R LEARNING ABOUT THIS METHOD AND U DON'T KNOW WHAT UR DOING.IT CAN COMPLETELY DESTROY UR RECEIVER IF U DO LITTLE MISTAKE WHILE JTAG'ING.

    DON'T AFRAID BY THIS WARNING BCOZ. I DON'T WANT TO HEAR IF UR RECEIVER DEAD WHILE U LEARNING THIS.AND DON'T WANT TO DIRTY THIS THREAD BY SHOUTING UR MISTAKES WHILE DOING THIS TOOL.SO THAT WE CAN GIVE VERY GOOD WORK TO RDI ADMINISTRATORS AND MODERATORS.

    ONE THING IS U DEFINITELY NEED TO PLAY WITH MANY RECEIVERS AND DON'T HEED DESTROYING ONE RECEIVER WHILE U R LEARNING.I ALSO DESTROYED MY RECEIVER.LOL: I'M NOT A MACHINIST , I DON'T KNOW ABOUT ICs , CAPACITORs, RESISTORs BUT I CAN DO THIS THING SO THAT WHY ARN'T U ? TRY THIS FRIENDS.##

    Thanks alot to Mr. Farukh , Mr. Cobra , Mr. Kevo and other JTag guru to give ur methods on internet and ur help.

      Re: TECHNICAL SECTION ABOUT JTAG FOR NEWBIES

      WHAT'S JTAG ?

      JTAG is an interface that you can make urself or buy which allow you to erase and reprogram ur receiver's flash rom.Why u should use this JTag?In case of ur receiver become unusable bcoz. of upgrading with wrong software or if you upgrade with wrong method.Meanwhile u need a special software to alive ur receiver again.That's JTag.

      JKEYS

      jKeys is a program primarily used to access memory on IRDs. It works by utlizing processor diagnostic devices via the JTAG port. This software has been used on STMicroelectronics STiXXXX (ST20 based core) and LSI SC2000 processors.

      FLASH ROM

      Your receiver flash rom can be erase and program again and again like a CD RW.Uploading wrong firmware into your receiver will not damage your flash rom but only render your receiver useless.If you happen to load the wrong file into your receiver you can use Jtag to reprogram ur flash rom.
      If Jtag can read your flash rom , box keys then the flash rom has no problem.It's more safer to use Jtag than to use Null modem cable to upgrade your receiver.

        thanks yan for your tremendous efforts, what tools do we require to start jtag, for all to know, does it depend on particular receiver or one j tag cable will work for any receiver, and can i use j tag to change the firmware in one receiver to another, lets say eurobox to neosat, or you can only jtag to original manufacturer soft/firmware.
        just an introduction, take your time

          HOW TO BUILT A SIMPLE JTAG CABLE

          1.25 Pin Male header (Printer Cable)
          2. 4 pieces of 100 ohm resistor
          3. 1 piece of 33 ohm resistor
          4. 6 pieces of wire (longest 12 inches or as short as possible)

          PIN ASSIGNMENT


          25 Pin <-------> Receiver
          Cable

          Pin 2 <-------> Pin 9
          Pin 3 <-------> Pin 11
          Pin 4 <-------> Pin 13
          Pin 5 <-------> Pin 19
          Pin 13 <-------> Pin 15
          Pin 18 to 25 <-------> Pin 20

          Here is the schematic diagram to built a jtag cable for 20 pins.

            All JTAG PIN ASSIGNMENT


            As u know there r many receivers' brands in every regions.So that there r many pins lay out for them.As far as I know there r 20 Pins, 16 Pins , 14 Pins and 10 Pins for JTag.So that u need to open ur receiver's cover and search for how many Jtag pins.Tomorrow I'll post some pin assignment.

                HOW TO USE

                Back up ur receiver

                1.Power off ur receiver.(remove all connection cable)

                2.Connect JTag connector to PC parallel port and receiver.Power up ur receiver.

                3.Run Jkeys and clcik on "detect".It'll show "Device ID" and Device on dialogbox.
                (if not show "Device ID" and "Device",ur connection will be wrong and u can't erase or program ur flash).

                4.Select IRD model and then click "Flash Programming".Don't heed any warning.

                5.Click "Read" button and save this file in ur PC.Remember keep it on save place and this DOC file is ur receiver's memory.

                This file size will always (2,097,152 bytes) for 2M flash and (1,048,576 bytes) for 1M flash.

                            Dear Sir cogil, Thanks alot.Sorry for my delay bcoz. I'm not getting well with my dial-up connection.
                            Mostly 20 pins cable will works for 20 pins receivers,10 pins cable will works for 10 pins receivers.Yes u can change software with this tool but ur flash rom no: is need to same with another flash rom.And working component of main circult must be same with another.Generally u can't do it.

                            Regards.

                              Error DCU

                              "Error reading from DCU (DCU Peak)" while u run Jkeys

                              What's DCU


                              DCU stands for Diagnostic Controller Unit. This is utility for sending commands to STi55xx from outside. Here is the main problem if the BOOT record does not exist, STi chip does not know what the DCU is in the first place. This is the reason for apperaing "Error reading from DCU (DCU Peak)" message while u open Jkeys.

                              In case we are going to use program named as Wall.exe.
                              Plz. do this document before action.

                              1. Rum wall.exe

                              2. It will appear "Warning! The ID is code is incorrect" Ignore this message and click Ok.

                              3.. Click “REFRESH” button

                              4. Do not close Wall.exe

                              Then open JKeys and do as usual.
