Re: Genode Hack'n Hike 2013
by Norman Feske 23 Mar '15

23 Mar '15

Hello everyone, the date for this year's Genode Hack'n Hike held during 11-16 of September is approaching. Genode's developers will spend those days in the beautiful scenery of the Bohemian Switzerland, relaxing, hiking, and hacking on fun side projects. The Hack'n Hike will be the perfect setting for getting involved with the community, catching up, or just hanging out with the Genode crowd. There is still room for more participants. Genode Labs sponsors the event. So your participation/accommodation is free. If you like to join in, please get in touch by writing to hacknhike@...1... or commenting on https://github.com/genodelabs/genode/issues/793.

Re: Porting on i.MX6
by Aditya Kousik 23 Dec '13

23 Dec '13

Hello Firstly, thank you for patiently replying to our queries and debugging issues so far. We're trying to port Genode onto an i.MX6, which we've realised is no easy task. Our initial approach to this was to tweak existing i.Mx53 files and make corresponding changes (arm cortex a9, created imx6 related folders in include). As pointed out to us by Stefan, this was completely off track as the memory layout may be mixed up (or many more issues). Here's a brief reboot of our attempt: 1. edit create_builddir to add a rule for imx6 board and added build.conf.hw_imx6 in builddir folder. 2. modify board_base.h in base/include/platform/imx6/drivers and fill with addresses by referring to the imx6 reference manual. (We also added CORTEX_A9_CLOCK and private memory base) 3. read through the Makefile and added spec-hw_imx6 and spec-platform_imx6 respectively. 4. created imx6 folder with files in os/include/platform/imx6 as well. (All with imx53 as reference) Make: Since the drivers for imx6 would take a long time to code, we are NOT running demo.run. We tried to build hello.run (without building drivers/timer) according the instructions given in your site. We're getting the following error: Program core/imx6/core COMPILE _main.o ASSEMBLE boot_modules.o COMPILE console.o COMPILE context_area.o COMPILE cpu_session_component.o COMPILE cpu_session_support.o ASSEMBLE crt0.o COMPILE dataspace_component.o COMPILE dump_alloc.o COMPILE io_mem_session_component.o COMPILE io_mem_session_support.o COMPILE irq_session_component.o COMPILE kernel.o COMPILE kernel_support.o COMPILE main.o make[3]: *** No rule to make target `mode_transition.o', needed by `core'.

Fosdem'14
by Sartakov A. Vasily 03 Oct '13

Hello, my dear friends. I am sorry if you receive multiple copies of this message (but I know, most of you will receive copies), but mailing list from uKernel dev room at FOSDEM'13 was destroyed (https://lists.fosdem.org/listinfo). Time rolls on, a FOSDEM'14 is not too far and now it is good time to submit a "uKernel and component based os" dev room. Who would like to organize dev room in this year? I would be proud to make this, but I heard someone from TUD would like to organize Dev room in this year. -- Sartakov A. Vasily sartakov@...104...

Using C++11 by default
by Norman Feske 17 Sep '13

17 Sep '13

Hello, I would like to go with the times and switch Genode to use C++11 by default. This will enable us to solve a number of problems in a more elegant way, e.g., by using variadic templates for the RPC framework, we can possibly get rid of the current limit of the number of RPC functions supported by the 'GENODE_RPC_INTEFACE' declarations. Are there any objections from Genode users? For example, is anyone of you still using a custom tool chain that does not support C++11? If no one disagrees, I would go forward and add '-std=gnu++11' as default argument to g++. Regards Norman -- Dr.-Ing.

Bringing up Genode run/nested_init on a Beaglebone.
by Bob Stewart 31 Aug '13

31 Aug '13

I'm try to get a basic Genode setup working on a Beaglebone Black (TI AM335x processor). I'm using a version of u-boot specifically built for the Beaglebone Black from Robert Nelson's eewiki pages. The only modification I made was to allow for elf file commands. Carefully following how the PandaBoard and the imx53 platforms were build I successfully built from base-hw an elf image for run/nested_init and loaded that onto an SDCard which contained the two stages of u-boot. (Previously, I had succesfuly built a helloworld test version of Fiasco.OC and successfully manually booted it from an SDCard with the same MLO and u-boot.img files. So the basic process of booting an elf image file works.) The elf image is built to load and 0x81000000 with u-boot using the space from start of SDRAM at 0x80000000. The elf file header has an entry point address of 0x81004DC0. Booting the Beagleboard into u-boot from the SDCard, manually loading the elf image file to the load address above, and giving it a"go" command to the entry point address, I get an "application terminated" message as shown below in the console output through minicom: . . . *U-Boot# load mmc 0 0x81000000 image.elf** **reading image.elf** **604700 bytes read in 73 ms (7.9 MiB/s)** **U-Boot# go 0x81004dc0** **## Starting application at 0x81004DC0 ...** **## Application terminated, rc = 0x8108C004** **U-Boot# * At termination, the output above shows rc to be pointed at 4 bytes beyond the start of the bss section of the image. I would have expected to see at least some Genode core debugging messages, at least. Is core not being executed at the entry point? I believe I have the Board_base stucture and cores cpu, pic, platform_support, timer and tlb files correctly set up for the AM335x. Thank you for any help you can provide. Bob Stewart

Genode Source building
by Venkada Ramanujam 23 Aug '13

23 Aug '13

Hi, Complete building and installation for Genode source code is not available. So can i follow below steps. will it work ? 1.Extracting available genode.iso 2.compile only particular code (ex:lwip,nic and netperf for improving tcp/ip performance). 3.replace with existing files (lwip,nic and netperf) with extracted directory (at step 1). 4.again make iso for that directory 5.run with qemu. is it correct or not? or any other procedure for building source and creating iso for genode source.

Regarding enabling USB 3.0 in Exynos 5 SoC
by jaeyong yoo 22 Aug '13

22 Aug '13

Hello Genode, I saw that you have successfully enable USB 3.0 in Exynos 5 SoC (Arndale board): http://genode.org/documentation/release-notes/13.05 I'm trying to enable USB 3.0 in native Linux on arndale board and having some trouble. I'm using recent branch of Linux 3.11 kernel with u-boot in Linaro for arndale board. After booting, I can see xhci module is properly installed, but plugging the usb network dongle to USB 3.0 port does not generate any interrupts. Very much appreciate any hints or references for enabling USB 3.0 in native Linux. By any chance, do we have to change some parts in u-boot for power up the USB 3.0? Thanks, Jaeyong

MMIO generation tool
by Martin Stein 20 Aug '13

20 Aug '13

To ease the creation of drivers for Genode I've written a shell script that takes simple Register specs as input and generates appropriate MMIO-framework declarations as output. As an example this input: r M0_grp0_span 28 32 b Span 0 15 t M0_grp0_xy 32 b Y 0 11 b X 16 11 x M0_grp0_sxy M0_grp0_xy 2c x M0_grp0_dxy M0_grp0_xy 34 r M0_grp0_wh 30 32 b Height 0 11 b V_scale 12 2 b Width 16 11 b H_scale 28 2 Would result in this output: struct M0_grp0_span : Register<0x28, 32> { struct Span : Bitfield<0, 15> { }; }; template <unsigned OFF> struct M0_grp0_xy : Register<OFF, 32> { struct Y : Register<OFF, 32>::template Bitfield<0, 11> { }; struct X : Register<OFF, 32>::template Bitfield<16, 11> { }; }; struct M0_grp0_sxy : M0_grp0_xy<0x2c> { }; struct M0_grp0_dxy : M0_grp0_xy<0x34> { }; struct M0_grp0_wh : Register<0x30, 32> { struct Height : Bitfield<0, 11> { }; struct V_scale : Bitfield<12, 2> { }; struct Width : Bitfield<16, 11> { }; struct H_scale : Bitfield<28, 2> { }; }; It fastens my workflow a lot when adding many new registers at a time. The tool can be found as 'tool/mmio' in my branch https://github.com/m-stein/genode/tree/tool_mmio. This branch is not meant to be merged into genodelabs/master and is updated manually. To print the tools manual call the tool without an argument. If you have further questions don't hesitate to ask me. Martin

Genode Installation details
by Venkada Ramanujam 16 Aug '13

16 Aug '13

Hi, I did following steps, cd <genode-dir> ./tool/create_builddir linux_x86 BUILD_DIR=build.lx cd build.lx make run/demo One "Launchpad" window is appeared. After that what can i do. How can i build complete source codes and create iso image for that genode source code and also installation. can any one tell me steps if anymore there. With Reg, VENKADA RAMANUJAM.S 9578520238
