| 03:00.27 | Ian_Daniher|XO | a long long time ago someone in here said that they got bluetooth-audio up and running with a headset |
| 03:02.10 | Madsy | With UMULL on ARM, RdHi, RdLo and Rm must be different registers, but Rs can be the same register as any of the others. But ARMARM lists the multiplication as two multiplications with Hi and Lo respectively. If that was the case and Rs = RdHi, wouldn't RdLo = Rm*Rs give the wrong result? |
| 03:03.19 | Madsy | RdHi = (Rm * Rs)[63:32] and RdLow = (Rm * Rs)[31:0] |
| 03:03.20 | MonMotha | When in doubt, try it out. :) |
| 03:03.58 | Ian_Daniher|XO | could someone fess up and help me out? |
| 03:09.53 | MonMotha | sorry, the someone you're looking for isn't me |

| 06:41.27 | roxfan | Madsy: http://www.mail-archive.com/linux-omap@vger.kernel.org/msg00059.html |
| 06:44.50 | Madsy | roxfan: Thanks a lot :-) |
| 06:45.25 | roxfan | oh it's nothing, i just know google-fu |
| 06:48.39 | roxfan | btw here's an example from arm docs: |
| 06:48.42 | Madsy | There are other contradictions as well. The operands for UMULL is said to be signed, even though the multiplication is unsigned. That's a clear error which isn't even fixed in the issue I from 2005 |
| 06:48.45 | roxfan | <PROTECTED> |
| 06:48.45 | roxfan | <PROTECTED> |
| 06:49.48 | roxfan | "The UMULL instruction interprets the values from Rn and Rm as unsigned integers. It multiplies these integers and places the least significant 32 bits of the result in RdLo, and the most significant 32 bits of the result in RdHi." |
| 06:50.28 | Madsy | Yeah, I just read the page on keil as well. |
| 06:50.57 | Madsy | The ARMARM says something else, though, up to revision I. |
| 06:51.17 | roxfan | i think there's a newer one |
| 06:51.26 | roxfan | does your cover v6? |
| 06:52.17 | Madsy | Revision I does, which I have as a pdf. Revision E does not, which I have as a hardback. |
| 06:52.35 | roxfan | ok then i think it's the latest public one |
| 06:52.45 | Madsy | Thanks again. |
| 06:59.01 | roxfan | i wonder why they don't release v7 one |
| 06:59.12 | roxfan | what's so sensitive in it? |
| 07:05.24 | Madsy | For how long have it been unreleased? |
| 07:06.13 | Madsy | Perhaps their Mali chip is accessed as a co-processor? ;-) |

| 16:01.01 | Shani1 | hello |
| 16:04.08 | Shani1 | need help |
| 16:05.46 | solar | perhaps trying to be more verbose. Lots of ppl desire help. And depending on the question. The right somebody wont be able to answer it if you never just say what the problem is. |
| 16:07.15 | Shani1 | i am using router shiro corp dsl805e BusyBox v0.61.pre it is hanging when i telnet 2 or more times |
| 16:07.38 | Shani1 | then i have to reboot it to access it |
| 16:08.19 | solar | everybody is going to tell you to upgrade busybox before you probably get any help. |
| 16:08.33 | solar | but sounds like the kernel is not releasing the pty's |
| 16:08.36 | Shani1 | how to upgrade then |
| 16:09.22 | solar | build a cross compiler and upgrade it. |
| 16:10.08 | Shani1 | any easyway |
| 16:10.44 | Shani1 | i think the logs are full |
| 16:10.54 | Shani1 | how do i delete them |
| 16:12.49 | solar | man rm |
| 16:13.12 | mnemoc | *G* |
| 16:13.14 | solar | these questions make my head hurt. Off to find coffee |
| 16:14.04 | Shani1 | but i cannot see the log files so how can i remove them |
| 16:15.47 | MonMotha | I take it this device is running the stock/factory-provided firmware? |
| 16:16.03 | MonMotha | if so, you'll probably want to see if OpenWRT, DD-WRT, etc. supports it |
| 16:16.07 | Shani1 | yes |
| 16:16.18 | MonMotha | attempting to hack on factory firmware is generally not for beginners |
| 16:16.34 | MonMotha | the factory firmware is usually in the "well, it works - ship it" category |
| 16:16.39 | MonMotha | not easily tinkered with |
| 16:17.20 | Shani1 | MonMotha: right |
| 16:17.30 | solar | agrees 100% |
| 16:17.42 | Shani1 | MonMotha: can u solve my problem |
| 16:19.52 | MonMotha | no, I cannot |
| 16:19.55 | solar | probably not for under what the cost of the device is |
| 16:19.59 | Shani1 | i run this command to recoonect my pppoe |
| 16:20.00 | Shani1 | http://pastebin.com/m302d56ad |
| 16:20.00 | MonMotha | pretty much |
| 16:20.15 | MonMotha | if you are willing to pay me my consulting rate, I'll be happy to work on this for you |
| 16:20.24 | MonMotha | but otherwise it's just not an interesting enough problem |
| 16:20.36 | Shani1 | o.O |
| 16:20.42 | MonMotha | are you even supposed to have access to a shell on this device, or does it just happen to run telnetd? |
| 16:21.08 | Shani1 | no ssh access just telnet |
| 16:21.19 | MonMotha | shell != ssh |
| 16:21.25 | MonMotha | shell ~= command prompt |
| 16:21.37 | MonMotha | most consumer routers don't exactly advertise the fact that they run Linux or have a shell on them |
| 16:22.09 | Shani1 | ok it is |
| 16:22.13 | Shani1 | BusyBox v0.61.pre (2007.05.17-07:15+0000) Built-in shell (ash) |
| 16:22.21 | MonMotha | that's not what I'm asking |
| 16:22.35 | Shani1 | then? |
| 16:22.39 | MonMotha | what I'm asking is if this is an interface you are intended to use |
| 16:22.58 | MonMotha | I somehow doubt it, and as such I'm guessing they didn't pay much attention to whether or not it works |

| 16:23.46 | Shani1 | MonMotha: previously i have a chat with "gustavoz" |
| 16:24.05 | MonMotha | given that it's running the stock firmware (which just happens to be Linux based), you are effectively asking for customer support on a consumer electronic device. That's not really what we do here... |
| 16:24.38 | Shani1 | MonMotha: :( ok |
| 16:24.39 | MonMotha | in fact, this isn't really a "support" channel at all |
| 16:24.48 | MonMotha | most of the people in here are embedded systems professionals |
| 16:25.31 | Shani1 | that's why i came here for help because here are "embedded systems professionals" |
| 16:25.57 | MonMotha | yes, but embedded systems professionals are not generally people interested in providing end-user technical support |
| 16:26.09 | MonMotha | nor are we versed in the device you're attempting to use |
| 16:26.42 | Shani1 | ok |
| 16:27.25 | Shani1 | i wish "gustavoz" was here. He would have help me out :( |
| 16:27.44 | MonMotha | well, if gustavoz is willing to help, then I'd suggest you attempt to contact him when you see him again |
| 16:28.01 | Shani1 | i will ! |
| 16:28.06 | MonMotha | I don't think you're likely to get much help in here otherwise. That's just topical in this channel. |
| 16:28.13 | solar | Shani1: one key thing to note that got pointed out. There may already be projects out there that have a port for the device you are attempting to use. So try searching google if anybody else has the same device. And what they did |
| 16:29.21 | Shani1 | solar: i googled too much but no help. The only help i got was from here by 2 persons which are not present at the moment |
| 16:29.34 | Shani1 | brb |
| 16:31.13 | solar | anybody ever hacked up an old UPS? |
| 16:33.24 | MonMotha | never had need to |
| 16:33.31 | solar | I have an old 700W UPS. It takes 2 bats. Not sure if 2x6V or 2x12V. But they are long dead (for years). Was thinking in it's most simple mode I could remove the battries and use the device as a battery charger for the solar panel setup |
| 16:33.32 | MonMotha | what are you planning on doing? |
| 16:33.55 | MonMotha | perhaps |
| 16:34.09 | MonMotha | there's not much to a lead acid battery charger, though |
| 16:34.41 | MonMotha | constant current until the charge voltage is reached, then constant voltage until you get to a set charge current termination threshold, at which point you shut it off or float it |
| 16:38.44 | MonMotha | the battery chargers in cheap UPSes are often pretty dinky, too |
| 16:39.01 | MonMotha | that's one reason they take some damned long to charge |
