RJTAG chip doesnt flash while trying to boot to xell

[DarkThirty]

Console Type: (Jasper)
NAND size: 16
Dashboard version: 16537
CB version: 6754



Hello all. I have installed the rjtag kit. dumped nand 4 times and all 4 match. created xell reloaded and wrote to nand however when i go to boot xell nothing happens. screen stays black and my rjtag chip does not blink or flash at all. am i supposed to have the jr programmer hooked up as well when im booting to xell? what else do i need to show you guys?

Was the console working before you started: Y

Is the red led lite up when the psu is plugged in? Where is your jrunner log? Alot of your soldering points look cold soldered use more flux or change your solder.

Thanks for replying. No my psu light is green. No RROD. there is not post though. I have used flux on every solder joint ive done. you can see the residue on some of the boards.

here is a rater screenshot of whats going on. no post

i see the residue but your points dont look good. what kind of solder are you using? the red led on the rjtag not the psu?

 

[DarkThirty]

Im using alpha fry 60-40 rosin core solder. so light on chip at all. is something not connected?

Make sure the flex cable is connected properly.

Did you tick r-jtag/aud clamp in jrunner?

i did

if one of the points isn't connected though, would that cause the chip to not power or is it a faulty chip? because it doesnt flash or have lights on it at all when the box is turned on.

Retouch all the points on the nand qsb, does the rjtag chip have the red power light on at all?

You don't have your POST ribbon connected to the R-JTAG.

Or it Looks like you programmed the rjtag chip with an RGX XSVF.

no there is no light on the chip whatsoever

i took the photos while i had the board out and apart so the ribbon cable was disconnected at the time but its in when im booting. how would i have programmed the chip? i read nand, created xell and wrote xell

actually i just realized the switch on the jr programmer was over towards xsvf when i wrote xell and not rjtag. is this the issue?

 

[jsinger47]

No, that switch wouldn't affect anything.

No, that switch wouldn't affect anything.

so why isnt the chip powering?faulty chip or i reprogrammed it (which i can guarantee i did not)

With the console plugged in measure the voltage on the 5V point on the RJTAG chip. It should obviously be 5V

should i remove the jr programmer when booting to xell or does it matter if its connected or not

do you have the black connector msrked tms,tdi,tdo connected? my lights go out when its connected

I tried it with that cable connected to the jrp qsb but the console just rrod's

What does this have to do with R-jtag. you shouldnt be connected the cr program cable at all. Like i said you soldering on the qsbs looks like there cold solder. and if you dont know what the red led is on the rjtag board then you need to read the guide again as thats the simplest thing to know.
