RGH extrem bad glitching times on my Jasper 512mb :(

[blabliblub]

Hey guys
I RGH'ed around 5, or 6 consoles, but this 512mb Jasper was the first which have problems. Sometimes it doesn't boot, or it takes a while, but must times it doesn't glitch...

Some informations about my console:
-Jasper 512mb BB
-Kernel 14719
-used tool: J-Runner & Multibuilder 0.7 & Multibuilder 0.82 (no difference )
-CoolRunner: TX CoolRunner rev. a

The solder looks good and maybe it would solve the issue with the glitching times if I use the TX CoolRunner rev.B?

Have you soldered a cap across GND and CPU_PLL_BYPASS on the CoolRunner?

 

[blabliblub]

yep, but it doesn't helped

This may help you, it is a possible fix for "stubborn" Big Block Jasper units.

I had this once and it turned out that the cap i had was no good fitted another and all was good

might be worth just trying quickly

I will try it when I have enough time for it and I will tell you my results

You should tweak your cpu_rst wire and pll_bypass wire to get good timing and yes you should also use the 68nf cap between gnd and pll_bypass for 512mb jaspers.
