| 07:54.36 | av500 | what hw? |

| 08:01.27 | Kasreyn | (i know i shouldn't ask questions the require months of research) |
| 08:01.43 | av500 | does it have DT stuff? |
| 08:01.52 | Kasreyn | DT? |
| 08:01.52 | av500 | I fear a board file is not going to fly any more on lkml |
| 08:02.08 | Kasreyn | yes i understand that. and i want to move it forward |

| 08:02.22 | av500 | ok |
| 08:02.44 | Kasreyn | yeah.. device tree, nothing is written for it yet |
| 08:03.36 | Kasreyn | you could get a 3.9 to boot without it though? |

| 14:42.17 | landley | Kasreyn: I just fixed my arm IRQ issue and have qemu's versatile board working again. Should be cutting a release today. |
| 14:42.21 | landley | Might give you a starting point? |
| 14:42.53 | *** join/#edev Crofton (~balister@65.14.229.26) |
| 14:43.28 | landley | Kasreyn: and the early_printk() stuff usually gives you a reasonable starting point for serial. That's the no-irq, spin on the status bit and send a byte when it clears version. |
| 14:46.56 | Kasreyn | landley: you confuse me.. :) |
| 14:48.28 | Kasreyn | never used early_printk |
| 14:49.22 | landley | https://www.kernel.org/doc/menuconfig/arch-arm-Kconfig.debug.html#EARLY_PRINTK |
| 14:50.01 | landley | It's basically a very simple set of output-only drivers that do not use interrupts. |
| 14:50.21 | landley | They've got several serial chips, vga console, a couple ethernet drivers for netconsole, and so on. |
| 14:50.38 | landley | Once the boot proceeds far enough, that driver's discarded and the real interrupt based driver is switched to. |
| 14:51.05 | landley | Otherwise the kernel buffers all the printk data in the dmesg buffer until it can enable interrupts, and then spews the backlog all at once about halfway through the boot. |
| 14:51.35 | landley | If something goes wrong before then, you never get any printk output unless you can look at the dmesg buffer via jtag or some such. |
| 14:52.03 | av500 | or on next boot if you have android ram_console :) |
| 14:54.41 | Kasreyn | landley: i've noticed the block buffering.. before registering the UART it did early setup. i miss it now want to go back.. |
| 14:57.29 | Kasreyn | something between 3.2.40 and 3.3.8 breaks my port. multiple changes to arch/arm/mach-* i should look into.. |
| 14:59.11 | Kasreyn | things like: "replace entry-macro.S with a .handle_irq function in the machine descriptor" |
| 15:05.47 | Kasreyn | it's not doing irq domains that's for sure |
| 15:19.40 | *** join/#edev Anaphaxeton (~george@athedsl-4454696.home.otenet.gr) |
| 15:25.15 | landley | Kasreyn: the versatile irq handling was deeply screwed for 7 consecutive months. They broke it 3 times in a row. |
| 15:25.18 | landley | I was kind of impressed. |
| 15:25.28 | landley | At lunch I'll go rsync my blog and then point you at it. |

| 16:32.42 | XandriX | landley: quick question jtag wise what prog to you use is it openocd ? or are you a goodfet user like myself |
| 16:33.00 | landley | openocd. |
| 16:33.04 | landley | prpplague set it up for me. |
| 16:33.08 | XandriX | aaah cool |
| 16:33.20 | XandriX | so your using wiggler jtag ? |
| 16:33.24 | landley | I don't use jtags all that much, I just like to know how. :) |

| 16:33.29 | landley | I was using whatever was built into the nail board. |
| 16:34.00 | XandriX | i meant as your connector its a db25 connected to your pc i take it ? or do you have a fancy usb jtag interface |
| 16:34.10 | landley | If I'd gotten a beaglebone at the CELF demo I'd poke at that, but they kept 'em instead of giving them out. Oh well. |
| 16:34.17 | landley | usb |
| 16:34.25 | landley | The nail board had a usb hub built into it. |
| 16:34.38 | XandriX | wonders what the nail board is |
| 16:34.41 | landley | Powered the board, provided serial, jtag, and a usb gadget interface. |
| 16:34.58 | landley | Xandrix: it was sort of a proto-raspberry pi. About 3 years earlier. |
| 16:35.05 | XandriX | aaaah |
| 16:35.07 | XandriX | cool |
| 16:35.27 | XandriX | i use a goodfet to jtag devices its pretty shmancy for the price and there is a port so you can use openocd with it |
