If you have enabled the CAP on REV B of the TX CoolRunner, simply un-bridge it and try a 47nF cap instead as per the instructions above. Try different values of capacitors and wires. If your LED stays on or does not come on at all, it is usually because of something being wrong with PLL_BYPASS. The debug LED should flash on for less than a second and repeat every 5 seconds. Using a TX CoolRunner Rev B, and after applying various troubleshooting measures we have had glitches ranging from instant to 20 minutes. (If you have a genuine TX CoolRunner REV B this is already included in the design so not required)Īn easy to follow picture guide can be found here: (If you have a genuine TX CoolRunner REV B you can use the on-board by bridging the CAP jumper)Ī 220-270pf capacitor should be added between CPU_RST(+) and GND(-) on the cpld. C7R112 (located near the xclamp under the CPU) must be de-soldered, and the CPU_RST wire from the TX CoolRunner(D) must be soldered to the left pad (non grounded pad).Ī 47nf ( 0.047uf) capacitor needs to be added between PLL_BYPASS(+) and GND(-). The Xenon has a capacitor on CPU_RST that was removed in later models. Program your TX CoolRunner (or whatever flavor RGH mod you are using) with the tx-xenon.xsvf or tx-xenon.jed file. Generate your ecc image using the latest version of J-Runner and flash to your NAND (+w16 just like a regular RGH).

Here is the readme included with the release: This is by no means meant to be used for an everyday RGH as its as bad if not worse than a Zephyr, however it does work and will be perfect for those who have a Xenon where they lost their DVD key or an unbanned key vault. We are happy to finally release the Xenon RGH Hack.
