| FatPhil | It was a silicon quality issue, IIRC, and some devices were worse than others. | 19:30 |
|---|---|---|
| DocScrutinizer05 | so verdict revised: SR still has potential to cause memory corruption, but odds are you got one of a batch with better silicon that doesn't show this problem | 19:33 |
| DocScrutinizer05 | but odds also are you blame the last SHR update when somethig goes haywire, though in fact you got a lemon with poor silicon and SR caused RAM corruption | 19:37 |
| ShadowJK | From TI's point of view, and what they usually did for other things, it's "oh we forgot to burn calibration. No matter, we'll do it in the next silicon revision, bug closed" | 20:07 |
| FatPhil | DocScrutinizer05: after sniffing around, it appears that the more recent silicon was much better, and it was considered "fixed, but we're still not willing to risk it" | 20:16 |
| freemangordon | FatPhil: and are there N900s in the wild with the "old" silicon? | 20:17 |
| FatPhil | Trying to work out how to tell silicon versions... | 20:18 |
| FatPhil | Die ID: 0200600a 04014023 00000000 1fde0004 <- early silicon | 20:28 |
| DocScrutinizer05 | anyway they recently built a silicone ball IPK iirc | 23:10 |

| kerio | as in, running one won't make the cpu blow up because of the silicon errata | 18:40 |
|---|
| DocScrutinizer05 | btw about OMAP bugs, did I tell about that non-public silicon error in omap4 WONTFIX, that causes IRQ misses? | 15:50 |
|---|
| kerio | (there's a silicon errata from texas instruments regarding the thumb2 ISA) | 17:34 |
|---|
| DocScrutinizer05 | why get chips with such a silicon erratum ever sold and mounted to a PCB? that's the right question | 10:50 |
|---|
| DocScrutinizer05 | and it seems there's been a silicon erratum in TWL4030 regarding OTG in the early chips | 15:49 |
|---|
| DocScrutinizer05 | luckily this old silicon gravejard is awaiting some retirement now | 01:43 |

| DocScrutinizer | RST38h: I already spent THREE hours reading thru errata and mostly talking to people who investigated all that the *right* way by actually understanding what's the nature of the problem and if and how it might get fixed - they all tell me it *can not* get fixed for our silicon. Now you suggest I invest more of my precious time for freemangordon's "I don't buy it"? MEH | 16:12 |
|---|---|---|
| RST38h | Doc, not being able to fix something in silicon does not mean you cannot fix it in software | 16:16 |
| DocScrutinizer | [2011-12-03 16:39:19] <DocScrutinizer> unless he came up with a *comprehensive* list of *all* silicon errata in 3430, and analyzed each single one of them and explained how his workaround is proven to deal with it so it won't cause anymore problems | 16:26 |

| DocScrutinizer | it got Silicon Errata | 17:40 |
| amiconn | (silicon bug, gcc bugs however are rather likely) | 00:00 |
|---|---|---|
| DocScrutinizer | what's unlikely in silicon bugs? | 00:00 |
| Raimu | Lol, silicone | 00:00 |
| DocScrutinizer | silicon bugs are virtually impossible to rule out on a WFM-basis | 00:01 |
| freemangordon | i've been searching for some silicon bugs re CortexA8 and thumb, find nothing. while gcc bugs... | 00:02 |
| DocScrutinizer | if there's been such word about silicon bugs in N900 thumb, then it came from Nokia devels | 00:04 |
| DocScrutinizer | http://www.google.de/search?q=cortex+A8+silicon+errata&ie=UTF-8&oe=UTF-8 | 00:21 |
| DocScrutinizer | [2011-12-02 06:35:21] <DocScrutinizer> that's what silicon bugs are like, yes :-) thanks anyway for confirming it, as freemangordon wasn't inclined to trust in my words | 07:35 |
| DocScrutinizer | I feel like mentioning again there have been rumours about thumb having SILICONE bugs on N900 | 23:58 |

| DocScrutinizer | friggin silicon gremlins | 20:44 |
|---|
| DocScrutinizer | to shorten the boredom a bit for the rest of you: I fixed my fan with a proxxon mill by milling a small hole slightly off axis to the fan blade plastic and then "filled" the whole thing with good amount of silicone oil | 19:14 |
|---|
| DocScrutinizer | btw CPU fan: I did a major hw surgery on mine, dremel'd an aperture to plastic of fan blades spinning part *around* the axis, found a brass cylinder underneath, and "filled" it with silicone lubricant. Works now like it's new | 22:57 |
