Revision as of 11:06, 9 June 2013

The article Raspbian was nominated for deletion. The discussion was closed on 22 December 2012 with a consensus to merge the content into Raspberry Pi. If you find that such action has not been taken promptly, please consider assisting in the merger instead of re-nominating the article for deletion. To discuss the merger, please use this talk page. Do not remove this template after completing the merger. A bot will replace it with {{afd-merged-from}}.

This page is not a forum for general discussion about Raspberry Pi. Any such comments may be removed or refactored. Please limit discussion to improvement of this article. You may wish to ask factual questions about Raspberry Pi at the Reference desk.

Nomination of Raspbian for deletion

A discussion is taking place as to whether the article Raspbian is suitable for inclusion in Misplaced Pages according to Misplaced Pages's policies and guidelines or whether it should be deleted.

The article will be discussed at Misplaced Pages:Articles for deletion/Raspbian until a consensus is reached, and anyone is welcome to contribute to the discussion. The nomination will explain the policies and guidelines which are of concern. The discussion focuses on high-quality evidence and our policies and guidelines.

Users may edit the article during the discussion, including to improve the article to address concerns raised in the discussion. However, do not remove the article-for-deletion template from the top of the article.

Please change the memory on the Model A to 512MB as it now has the same memory as the Model B. 50.43.89.24 (talk) 23:33, 10 May 2013 (UTC)

 Not done The model A still has 256MB of RAM, not 512MB! Originally the model A was planned to have 128MB of RAM but by the time of the actual launch the RPF managed to increased it to 256MB.

So unless you have a source that proofs that the model A now has 512MB the current information is still correct. Mahjongg (talk) 00:54, 11 May 2013 (UTC)

 Not done: per Mahjongg, (change the |answered= parameter to yes next time). Michaelzeng7 (talk) 01:27, 11 May 2013 (UTC)

The Raspberry Pi Camera has just been released. Please update! Nagol68 (talk) 20:27, 20 May 2013 (UTC)

 Not done: it's not clear what changes you want to be made. Please mention the specific changes in a "change X to Y" format and provide a reliable source if appropriate. —KuyaBriBri 21:15, 20 May 2013 (UTC)

Wrong numbers?

The articles currently says:

In the highest ("turbo") preset the SDRAM clock was originally 500 MHz, but this was later changed from to 600 Mhz because 500 MHZ sometimes causes SD card corruption. Simultaneously in "High" mode the core clock speed was lowered from 450 to 250 MHz.

Higher clock speed because lower causes corruption? "changed from to"? A drop almost 50%? Could someone please check these numbers? --Guy Macon (talk) 12:50, 8 June 2013 (UTC)

Disputed info from 121.72.118.83 on USB power and Memory clock

I found this addition which seems to be disputed because the reference is a forum thread. But I still find it useful. So it's here it is should anyone need it:

1. Originally the on-board USB ports were designed for USB devices using one "unit load" (100 mA) of current. Devices using more than 100 mA were incompatible with the Raspberry Pi, and for them a self-powered USB hub was required. However, due to user feedback, the RPF, at the end of August 2012, decided to remove the USB polyfuses which largely caused this behaviour. However, the maximum current that can be delivered to a USB port on these modified boards is still limited by the capabilities of the power supply used, and the 1.1 A main polyfuse. Spontaneous rebooting and/or crashing caused by hot plugging certain USB devices was introduced as a result of this change, which further reduced the standards compliance of the Raspberry Pi's USB implementation.

/../

1. The five overclock ("turbo") presets were changed because overclocking the core causes SD card corruption, apparently due to bugs in the BCM2835 SoC. They originally were:

1. 1. "None"; 700 MHz ARM, 250 MHz core, 400 MHz SDRAM, 0 overvolt,
   2. "Modest"; 800 MHz ARM, 300 MHz core, 400 MHz SDRAM, 0 overvolt,
   3. "Medium" 900 MHz ARM, 333 MHz core, 450 MHz SDRAM, 2 overvolt,
   4. "High"; 950 MHz ARM, 450 MHz core, 450 MHz SDRAM, 6 overvolt,
   5. "Turbo"; 1000 MHz ARM, 500 MHz core, 500 MHz SDRAM, 6 overvolt

Do we have any reliable sources for this? Яehevkor ✉ 08:54, 9 June 2013 (UTC)

I have included the source for the overclocking information with my latest edit: https://github.com/asb/raspi-config/commit/c5e1966418922862b2a84559c567c35e6a1c4c28 Surely this can't be disputed now? 121.72.118.83 (talk) 09:19, 9 June 2013 (UTC)

I'm not familiar with GitHub, can someone make a call of whether or not it's reliable? And what about the text attached to a forum post? Яehevkor ✉ 09:25, 9 June 2013 (UTC)

Alex Bradbury (asb) is the author of raspi-config and as you can see from the link I gave the overclocking settings were different when they were first introduced than they are now. They were added on 17 September 2012 and changed on 28 October 2012. This link shows that the reason for the change is due to SD card corruption, which is exactly what I said: https://github.com/asb/raspi-config/commit/a7a7b12ad0c0bf7e7fe9e1eadc4b35887230f2fb Somebody should add that to the article. I will eventually do that if nobody else can be bothered and would rather delete useful and relevant information instead. 121.72.118.83 (talk) 11:06, 9 June 2013 (UTC)
