| 19:18.32 | brooc | hno - where can I start? |
| 19:18.35 | hno | Max_nl_, maybe the kernel driver have some hint? It should set up clocks differently. |
| 19:18.37 | Max_nl_ | then why didn't it work with divider 3, but does work with 2, if lower frequency is ok? |
| 19:19.48 | brooc | Who is doing the kernel modules? |
| 19:19.49 | hno | Hmm.. good question. Maybe low frequency is not OK in MMC/SD mode and only SPI mide. |
| 19:20.32 | Max_nl_ | that's what I find difficult |
| 19:20.52 | Max_nl_ | I have no idea of what is the normal min. max. frequency range |
| 19:20.53 | hno | brooc, several people involved with different drivers. |
| 19:21.23 | hno | Max_nl_, the kernel driver almost certainly have a exact frequency it's trying to use. |
| 19:21.36 | Max_nl_ | I now just added to the u-boot I ship with my universal image: if lower then 300 mhz then use 2 |
| 19:21.44 | hno | kernel clock driver works on frequencies, not divisors. |
| 19:21.50 | Max_nl_ | which solves the problem for my problem board |
| 19:22.10 | Max_nl_ | but am afraid that tomorrow someone may try a different board, and find out it doesn't work |
| 19:22.13 | Max_nl_ | like my stuff to work everywhere |
| 19:22.28 | hno | That change is very unlikely to cause harm to anyone. |
| 19:23.13 | Max_nl_ | yeah, figured there may be few other boards that have lower then 300 mhz |

| 19:26.04 | hno | brooc, you don't need a dev board to do useful stuff, but usually more interesting to actually try running what you have done. |
| 19:26.21 | hno | so helps having some board with an appropriate CPU. |
| 19:26.59 | hno | brooc, where to start is the question I asked you above. What stuff you like doing most? |
| 19:27.34 | brooc | I am not sure yet |
| 19:27.52 | brooc | I would like to try kernel programming and the bootloader |
| 19:28.13 | brooc | both of which I think Ill enjoy |
| 19:29.06 | brooc | I have a RPi which is an ARM11 based SoC |
| 19:29.25 | hno | Yes, kernel and u-boot share a lot in programming style. |
| 19:29.47 | hno | but quite different in runtme environment. |
| 19:30.44 | hno | And both are almost 100% C. |
| 19:31.03 | brooc | I work in C and I like the language |
| 19:31.13 | hno | Good |
| 19:31.29 | brooc | I also enjoy asemblly |
| 19:32.13 | brooc | How should I begin |
| 19:32.38 | mnemoc | if you enjoy asm you might want to RE the gps driver ;-) |
| 19:32.46 | hno | In u-boot we currently have 2.5 projects. 1. Mainlining the changes. 2. NAND MTD driver. 3. Figuring out how to handle the variety of boards we have. |
| 19:33.10 | hno | mnemoc, we have no hardware to test that on. |
| 19:33.20 | mnemoc | fair point :( |
| 19:33.50 | hno | Hmm.. do the A13 have GPS pins? |
| 19:35.56 | brooc | What would you suggest for a beginner to look into? |
| 19:36.08 | brooc | Where can I read about all this? |
| 19:36.48 | brooc | The NAND MTD driver sounds interesting |
| 19:36.53 | hno | As you have no board then trying to port a driver to Linux-3.7 might be a good challenge. |
| 19:37.39 | hno | For the current MTD work you basically need a board + logic analyser. |
| 19:38.07 | brooc | And I have neither |
| 19:38.25 | brooc | Wouldn't qemu work? |
| 19:38.57 | hno | We have no documentation on the NAND controller so we need to experiement a bit and see what happens. |
| 19:39.33 | hno | QEMU works fine for generic ARM stuff, but not for A10 specific drivers. |
| 19:40.10 | hno | i.e. none of the work we do in u-boot or kernel. |
| 19:40.30 | vinifm | mnemoc? |
| 19:40.59 | brooc | How much does a board cost? |
| 19:41.06 | brooc | Where can I get one? |
| 19:41.19 | mnemoc | vinifm: yes? |
| 19:41.32 | vinifm | mnemoc: i could use: "#define UART_GET_CSR(port)__raw_readl(UARTx_BASE(1) + UART_LSR)" |
| 19:41.57 | techn | brooc: there many options.. http://linux-sunxi.org/Category:A10_Boards |
| 19:42.20 | vinifm | #define UART_LSR_THRE0x20 /* Transmit-hold-register empty * |
| 19:42.43 | brooc | hno, can please elaborate on your sugesstion regarding the port to linux 3.7 |
| 19:42.49 | hno | brooc, https://www.olimex.com/Products/OLinuXino/A13/ is one. |
| 19:43.02 | techn | http://linux-sunxi.org/Category:A13_Boards, http://linux-sunxi.org/Category:A10_HTPC, http://linux-sunxi.org/Category:A10_Tablets, http://linux-sunxi.org/Category:A13_Tablets.. |
| 19:43.38 | mnemoc | vinifm: experiment. you can't do any harm by reading ;-) |
| 19:43.42 | brooc | Thanks |
| 19:44.05 | hno | techn, you forgot http://linux-sunxi.org/Category:A10_Boards |
| 19:45.28 | techn | all of those should be good for dev work, but it's ofcourse easier if board has serial port already soldered.. like dedicated dev boards or mele's |
| 19:45.41 | techn | hno: couple row abowe :) |
| 19:45.57 | hno | brooc, recently a minimal port to linux-3.7 was done. This is still almost an empty shell and needs to be fleshed out with more drivers. |
| 19:46.02 | vinifm | the logic is right? BASE + SOME_REGISTER_UART |
| 19:46.24 | hno | and in the process those drivers needs updating to use device tree instead of hardwired configuration. |
| 19:46.38 | hno | vinifm, yes. |
| 19:47.03 | hno | with shift << 2 to word-align registers. |
| 19:47.05 | mnemoc | vinifm: almost everything in this world is readl/writel a base + offset ... |
| 19:47.32 | vinifm | if it works, it will be very cool :) |
| 19:47.54 | brooc | Just to make sure I understand you mean that there is a basic port of the linux3.7 kernel for the A10 core. Is that correct? |
| 19:48.09 | hno | brooc, yes. |
| 19:48.15 | brooc | If so what driver would you say is a good place to start with? |
| 19:48.21 | mnemoc | did arnd merge it already? |
| 19:48.40 | brooc | How do I setup my dev environment? |
| 19:48.49 | brooc | Where can I start reading? |
| 19:48.50 | hno | mnemoc, not sure. |
| 19:49.43 | techn | brooc: A13 core is also mainlined |

| 19:50.37 | mnemoc | hno: i2c maybe? |
| 19:51.35 | hno | Yes, that would be a good one, and extending the clock driver a bit too as needed. |

| 19:51.51 | hno | neither have i, mostly seen the bed. |
| 19:52.26 | brooc | Where can I start reading? |
| 19:52.38 | hno | brooc, sorry for the confused view here. It's just that a lot of things are happening. |
| 19:52.47 | mnemoc | work on the clock driver needs more knowledge |
| 19:53.26 | brooc | I am in the clock recovery team where I work |
| 19:53.39 | brooc | Not sure what you refer to as clock driver |
| 19:54.03 | Max_nl_ | Where can I get one? <- Can get A10 tablets at a lot of regular stores as well. Sold by electronic stores, toy stores and even a pharmacy chain here in NL. |
| 19:54.08 | brooc | How come Olimex do not sell A10-OLinuXino |
| 19:54.12 | hno | brooc, drivers/clocksource/ in the kernel tree. |
| 19:54.18 | hno | brooc, because it's not ready yet. |
| 19:55.10 | hno | or.. not sure any more. |
| 19:55.43 | hno | about clock driver. No that's not the right one. |
| 19:56.03 | brooc | hno, what should I start reading? |
| 19:56.13 | brooc | I have never ported a driver |
| 19:56.26 | hno | brooc, better start doing, and read bits you need along the way. |
| 19:56.47 | brooc | How do I setup a dev env? |
| 19:57.08 | brooc | I guess I'll need the sources from somewhere |
| 19:57.17 | hno | brooc, install a suitable cross-compiler. Pick an editor you like. And grab the sources using git. |
| 19:57.59 | mnemoc | puzzled |
| 19:58.19 | hno | mnemoc? |
| 19:58.53 | mnemoc | brooc confused me :) |
| 19:59.04 | hno | brooc, github.com/linux-sunxi/ has our repositories. But not sure where the 3.7 tree is currently. |
| 19:59.06 | brooc | How so? |
| 19:59.49 | mnemoc | you don't have a sunxi device or know where the sources are, and want to start porting drivers... |
| 20:00.10 | hno | is not pussled about that. |
| 20:00.23 | techn | berryboot installed for android.. lol :D |
| 20:00.52 | mnemoc | most people comes after having messed with a device in one or another way |
| 20:01.16 | hno | and some come to learn. |
| 20:01.21 | mnemoc | sure |
| 20:01.48 | brooc | Well, I posted on linkedin a post saying I would like to join an opensource group and was spointed here |
| 20:01.57 | brooc | I am trying to learn |
| 20:02.04 | mnemoc | brooc: aha! that was the missing link :) |
| 20:02.12 | mnemoc | brooc: now I understand |
| 20:02.29 | brooc | I have not heard of this project before |
| 20:02.43 | brooc | So I am working my way around this... |
| 20:02.57 | mnemoc | that was exactly my puzzling bit |
| 20:03.29 | mnemoc | the wiki is a good place to get familiar with the platform. and github.com/linux-sunxi/ for sources |
| 20:03.36 | brooc | I have built my own custom microchip based dev board with a WiFi device and Ethernet port |

| 20:49.38 | brooc | Yeah |
