hi all, trying to jtag a starview for a friend of mine.every time i try it,it comes up INIT JTAG IDCODE ;FFFFFFFF FAIL DCU,PLEASE RESTART OR RESET CPU BOX.have checked power is going in.i have tried this a load of times with no success. any ideas lads. jhaye2x
hi sc0user, thanks for getting back.i bought a solder free unbuffered jtag a good few months ago from some place in england.i have tested the c 11 capacitor and there is power coming from it. i am a bit new to all this. any help would be appreciated. jhaye2x
When you say you checked the caps do you mean you checked the power out from the PSU. Have you used the Jtag before and could you show me a link to it. Is it the one with a DB25 black shell and ribbon cable with no ground clip? Or is it one from Tailormadecircuits?
yes,checked the psu,it's ok,all the capacitors are showing power going through them.can't find the email where i bought the jtag.it is black shell for the parallel port,a Grey ribbon with A-N wrote on it.and a 20 pin holes with a red line indicating where to line it up.i have tried one jtag before with no success.hope this info is helpful. jhaye2x
Have you tried reversing the polarity of the ribbon on the header, i.e swap pin 1 (red line on ribbon) to pin 20. Basically turn the ribbon header upside down? Just twist it around the other way on the SV header. Are you using SkyMax or Jkeys and have you set your parallel port to an IRQ of 378 and ECP? You can do this in BIOS or Jkeys preferences. Apologies but heading soon, long drive in the morning
hi sc0user,hope your journey was ok. i tried the jkeys with irq at 378 that was fine.com port was at com 1, as i went into device manager and the com port was set at the correct one.when i tried the jkeys to detect it keeps coming up DEVICE ID 0x00000000 and UNKNOWN DEVICE. when i checked the capacitiors without the jtag in ,there was power going through all of them.but when i put the jtag on only a couple have power.which tells me the jtag draws all or most of the power supply. jhaye2x
sorry sc0user i meant ECP is the parallel port.when i am in the jkeys it is telling me that there is no JINTERFACE. my head is baffled. jhaye2x
Jinterface is for a serial Jtag. In Jkeys perference you must set it to Parallel Port, (that is what you are using), and port settings at 0x378. Also check as I said the polarity of the header. Your Jtag should have come with instructions. Is this not the case?
hi sc0user, tried polairty both ways no joy.i got a cd with the jtag for starview and eurovox.no name on it, blank disc.i am in the programme called (jkeys by d2) AND WHEN I HIT THE DETECT BUTTON,IT COMES UP COMMUNICATIONS ERROR(error,com1 already opened,stop the application currently using it and retry. i cant understand it. jhaye2x
Sorry but as said in my last post you need to change the Jkeys perference to para port. Here is a quick video tut for you http://www.mediafire.com/?sharekey=18ead8b417095971d2db6fb9a8902bda Its in exe format just click run after download. Dont worry its safe I just made it
hi sc0user, i have tried this jkeys preference loads of times today even before downloading it.the problem is,is that it is telling me that there is a communications error as in error in com 1 already opened.thanks for the download,but i still can't figure out the problem. jhaye2x
hi sc0user,i downloaded that video tut of jkeys.later i tried a eurovox jkeys and everything on that video you sent me worked on my pc. could you tell me what i do when everything is done as the same in the video.i hit the detect icon in the jkeys but what is next. hope to hear from you tomorrow as it is to late now. appreciate all you doing to help, jhaye2x
Jkeys are the same just different revisions. I presume it a Starview 1 we are talking about? Did it recognise it on Jkeys?
it is a starview i clone.last night i got past the detect icon straight on to the flash program.it was asking me for an IRD MODEL number .i did not know which one it was. later i was in a different site and a fellow said go into IRD model and go to 4900.but i was in bed at that stage.when i into jkeys today i can't even get past the detect button.still scratching my head. cheers jhaye2x
The box must be powered up to be flashed (don't worry about the lack of display or picture) Flashing with JKEYS ------------------- Run JKEYS and Detect. Should come up as: Device ID: 0x1D405041 Device: STi5518MVB-X Choose the IRD model as 4900 Flash would be 29LV160 Start : 7FE00000 Bytes 20000 Go into flash programmer. Erase chip first by clicking on Erase in the top right Flash chip with a working TSOP image by clicking on the top-right Program button. Flashing with S*YMax UP (Easier!) -------------------------------- If you are having problems flashing with JKEYS you can also use S*YUP. This is much easier to use. Click on 2mb (0x7FE00000) Click Start Click Erase Click Write Choose your flash image .. sit back and wait Thanks to SunRise SV TSOP Image is here you need winrar or other zip type program to unpack it. SkyMax is here (just in case). Again its in zip format.
hi sc0user, as i was saying i cant get past the detect button.it keeps saying (jtag device id =0x0000000) and (device =unknown device).i have tried skymax even with the new software you sent and i downloaded it with no joy. this jtagging is total head wrecking but i don't like giving in . jhaye2x
hi sc0user, i tried skymax with windows 2000 as the compatability.i got al the way till the end when it said TRAP WPTR 800000534 WRIRE FLASH ADR[7EE00000] LEN [000003EC]PLEASE WAIT. ERROR WRITING FLASH AT ADDRESS 80000000 ACK =00000100 WRITE FLASH END. SORRY FOR BEING A PAIN JHAYE2X
Nearly there. Try it in Win98 mode. But don't write first this time, erase twice, turn off SV after erase each time. Then write without pressing erase.
have tried what you said with win 98 mode changed the compatibility. told me ram fail it does not seem to work on that windows format.it keeps saying dcu failed.when i tried win 2000 with what you said in your last thread,it went all the way to the end then it said LOAD DATA RAM FAIL WRITE FLASH END. jhaye2x
