Reset iMX53-QSB from the secure world
by Ofer Hasson 16 Sep '15

16 Sep '15

Hey, I'm attempting to make a simple reboot feature on Freescale's iMX53-QSB. I'm currently working using the tz_vmm example. So, I understand that the way to achieve that on this board is through the watchdog timer, I followed the Linux kernel code that does this, and implemented a kernel module that does only the reboot part, this what i came up with: - volatile unsigned short *wdog1_base = (volatile unsigned short*) 0xf7e98000; *wdog1_base = (1 << 2); - This exact code, i a kernel module, does an immediate reset and i get the u-boot shell. All of this is done on the normal world of course, now i wish to have this in the secure world, Running the exact same code in the secure world, in the handle hypercall routine i get: - no RM attachment (faulter 129090 with IP 70014c28 attempts to write to address f7e98000) void Genode::Pager_object::unresolved_page_fault_occurred(): not implemented unknown signal context - Any idea's how to achieve my reset from the secure world ? Also, if someone could shed some light about the error, I'm not that familiar with Genode, just starting to work with it. Thanks in advanced.

Problem running demo on RaspberryPi
by Duss Pirmin 13 Sep '15

13 Sep '15

Hello After switching to 15.08 I can no longer run the demo on my RaspberryPi. For some reason the run script wants to include gpio_drv but doesn't build it. In repos/os/run/demo.run on line 21 the SPEC gpio dosn't seem to be set, as I do not see the building of the gpio driver. In repos/os/run/demo.run on line 70 the SPEC gpio is set, as the config contains the configuration for the gpio_drv. Best regards Pirmin Duss

Testing the SD_card driver in Odroid-X2
by Humberto López León 11 Sep '15

11 Sep '15

Hi Genode Community, I'm working on the implementation of SD card driver in ODROID-X2 (exynos4412) platform. I decided to reuse the implementation of SDHCI controller implemented by Norman Feske and Christian Helmuth. Essentially I only updated the memory map. I ran the sd_card and sd_card_bench tests, which ran successfully after making some arrangements in the corresponding .run files. I'm interested in trying this driver using the FAT32 file system, but running the libc_ffat example, an error occurs. Apparently the test attempts to create a directory and then open it, but fails when trying to open it. The serial output is as follows: L4 Bootstrapper Build: #32 Tue Sep 1 15:31:27 CDT 2015, 4.9.2 Scanning up to 2047 MB RAM Memory size is 2047MB (40000000 - bfefffff) RAM: 0000000040000000 - 00000000bfefffff: 2096128kB Total RAM: 2047MB mod11: 4130c000-413434c4: genode/platform_drv mod10: 412ce000-4130b640: genode/sd_card_drv mod09: 412b8000-412cd4b4: genode/libc_ffat.lib.so mod08: 412ab000-412b76f4: genode/test-libc_ffat mod07: 411ea000-412aa358: genode/libc.lib.so mod06: 4117b000-411e9068: genode/ld.lib.so mod05: 4113f000-4117aca8: genode/timer mod04: 410fd000-4113ec40: genode/init mod03: 410fc000-410fc4b6: genode/config mod02: 41097000-410fbe90: genode/core mod01: 41085000-41096368: sigma0 mod00: 41015000-4108431c: /home/humberto/SO/Genode/Repo_genode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco Moving up to 12 modules behind 41100000 moving module 00 { 41015000-4108431b } -> { 4142f000-4149e31b } [455452] moving module 01 { 41085000-41096367 } -> { 4149f000-414b0367 } [70504] moving module 02 { 41097000-410fbe8f } -> { 414b1000-41515e8f } [413328] moving module 03 { 410fc000-410fc4b5 } -> { 41344000-413444b5 } [1206] moving module 04 { 410fd000-4113ec3f } -> { 41345000-41386c3f } [269376] moving module 05 { 4113f000-4117aca7 } -> { 41100000-4113bca7 } [244904] moving module 06 { 4117b000-411e9067 } -> { 4113c000-411aa067 } [450664] moving module 07 { 411ea000-412aa357 } -> { 411ab000-4126b357 } [787288] moving module 08 { 412ab000-412b76f3 } -> { 4126c000-412786f3 } [50932] moving module 09 { 412b8000-412cd4b3 } -> { 41279000-4128e4b3 } [87220] moving module 10 { 412ce000-4130b63f } -> { 4128f000-412cc63f } [251456] moving module 11 { 4130c000-413434c3 } -> { 412cd000-413044c3 } [226500] moving module 03 { 41344000-413444b5 } -> { 41305000-413054b5 } [1206] moving module 04 { 41345000-41386c3f } -> { 41306000-41347c3f } [269376] Scanning /home/humberto/SO/Genode/Repo_genode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco -serial_esc Scanning sigma0 Scanning genode/core Relocated mbi to [0x4100e000-0x4100e232] Loading ode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco Loading sigma0 Loading genode/core find kernel info page... found kernel info page at 0x40002000 Regions of list 'regions' [ 40001000, 40001a3f] { a40} Kern ode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco [ 40002000, 4007efff] { 7d000} Kern ode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco [ 400a0000, 400a5fdf] { 5fe0} Sigma0 sigma0 [ 400b0000, 400b617b] { 617c} Sigma0 sigma0 [ 41000000, 410143f7] { 143f8} Boot bootstrap [ 4100e000, 4100e32f] { 330} Root Multiboot info [ 41100000, 41347c3f] { 247c40} Root Module [ 80100000, 80246663] { 146664} Root genode/core API Version: (87) experimental Sigma0 config ip:400a0100 sp:41013de4 Roottask config ip:80100000 sp:00000000 Starting kernel ode/GenodeOS/build/foc_odroid_x2/kernel/fiasco.oc/fiasco at 40001208 Hello from Startup::stage2 Per_cpu_data_alloc: (orig: 0xf006c0d8-0xf006cb28) Number of IRQs available at this GIC: 160 Cache config: ON ID_PFR[01]: 00001231 00000011 ID_[DA]FR0: 00010444 00000000 ID_MMFR[04]: 00100103 20000000 01230000 00102111 FPU0: Arch: VFPv3(3), Part: VFPv3(30), r: 4, v: 9, i: 41, t: hard, p: dbl/sngl L2: ID=4100c4c8 Type=1a340340 Aux=7e470001 WMask=ffff S=0 L2: Type L2C-310 Size = 1024kB Watchdog initialized SERIAL ESC: allocated IRQ 85 for serial uart Not using serial hack in slow timer handler.

nic_bridge with tap devices under linux_x86
by Marcus Nolte 11 Sep '15

11 Sep '15

Hi Genodians, I would like to test some networking-stuff under linux_x86 and have got a question concerning the use of the nic_bridge with the linux nic_drv. My setup is the following: For testing, I have created two tap devices which are used by two Genode 15.02 instances running on the same linux host. One instance is hosting a server application, the other the respective client, both using the lwip socket API. As long, as I only use the server and the client, everything is fine. In the next step I added additional components to the configuration which are also supposed to access the network. Thus I added the nic_bridge with a configured mac-address as a resource multiplexer and set the routes accordingly. The components in question successfully get an ip via dhcp. However, I do not receive any packets at the other end of the (virtual) line. - Infact it seems as if they do not even reach the nic_drv. When the bridge & nic_drv are initializing, I see the following lines on the server side (client'ts the same, except, of course, for the ip- and mac-address): [init -> nic_drv] --- Linux/tap NIC driver started --- [init -> nic_drv] Success [init -> nic_drv] Using tap device "tap1" [init -> nic_bridge] Invalid session request, no matching policy [init -> nic_bridge] --- NIC bridge started (mac=02:00:00:00:00:01) --- [init ->server] got IP address 192.168.56.106 As far as I read it from the mailing list / git commits, the "Invalid session request" message is not critical, correct? In a further simplified setup, I am using a single tap device with the nic driver, which is working flawlessly. As soon as I add the bridge I notice the same behavior as described above. In wireshark I saw a series of 3 ARP requests finished with a gratuitous ARP,if the bridge is not used. - The last one is missing if the bridge is used. If I read the code correctly those packets are purposely dropped in the nic_bridge. Am I missing / misconfiguring something here? I would be very glad about a pointer in any direction ;-) Cheers Marcus P.S: The route for the server looks like this: <route> <service name="Nic"> <child name="nic_bridge"/> </service> <any-service> <parent/> <any-child/> </any-service> </route> The config file entry for the bridge looks like this: <start name="nic_bridge"> <resource name="RAM" quantum="4M"/> <provides><service name="Nic"/></provides> <route> <service name="Nic"> <child name="nic_drv"/> </service> <any-service> <parent/> <any-child/> </any-service> </route> <config mac="02:00:00:00:00:01"> </config> </start> -- Marcus Nolte, M.

Hi Genode Community, I started using the Freescale i.MX53 QSB and was trying to run the Genode demo, following all the steps given in the 'getting_started.txt'. When I did the 'make run/demo' command I received this output: "/bin/bash: /usr/local/genode-gcc/bin/genode-arm-g++: cannot execute binary filedirname: missing operandTry `dirname --help' for more information.including /home/lucid/Desktop/genode-15.08/tool/run/boot_dir/linuxincluding /home/lucid/Desktop/genode-15.08/tool/run/power_on/linuxincluding /home/lucid/Desktop/genode-15.08/tool/run/log/linuxincluding /home/lucid/Desktop/genode-15.08/repos/os/run/demo.runbuilding targets: core init drivers/timer server/nitpicker app/pointer app/status_bar server/liquid_framebuffer app/launchpad app/scout test/nitpicker server/nitlog drivers/framebuffer drivers/input server/report_rom spawn make core init drivers/timer server/nitpicker app/pointer app/status_bar server/liquid_framebuffer app/launchpad app/scout test/nitpicker server/nitlog drivers/framebuffer drivers/input server/report_rom/bin/bash: /usr/local/genode-gcc/bin/genode-arm-g++: cannot execute binary filemake[1]: Entering directory `/home/lucid/Desktop/genode-15.08/build.lx'Makefile:107: *** "/usr/local/genode-gcc/bin/genode-arm-g++ version 4.9.2 is required".

Genode 15.08 NOVA Demo Blank Screen
by Thotheolh Tay 11 Sep '15

11 Sep '15

Hi, I am trying to run the demo and a QEMU appeared with a blank screen although before thr blank screen appeared it did display messages that looks like from the NOVA hypervisor loading. The log can be found on this pastebin: http://pastebin.com/8P3UF7Zt The image screenshot can be seen from: http://i.imgur.com/lp8uVvO.jpg Is it normal for the demo to appear as a blank screen. I remembered when I built he NOVA for 15.05 it showed a nitpicker GUI demo screen though. Regards, Thoth.

Reg: POSIX compliant c library
by kiran kumar 11 Sep '15

11 Sep '15

Hello , I am new to Genode, and wonderning is there any POSIX compliant C library which runs on top of genode itself not on noux runtime environment, if not available then how I can proceed to port any existing posix library to genode as I have to take care of linux system calls and signal handling mechanism provided by underlying kernel. -- కిరణ్ కుమార్ , భారత దేశం .

Uboot creation script fails
by Mark Albers 10 Sep '15

10 Sep '15

Hi, i use Genode 15.05 with the corresponding toolchain. Now, i have a problem with the uboot creation script. For example, when i build the hello-tutorial for hw_pbxa9 platform (in a fresh build directory), i get this error: make[1]: Verzeichnis »/home/mark/genode_git/build/hw_pbxa9« wird verlassen child process exited abnormally while executing "exec [cross_dev_prefix]readelf -h $elf_img | grep "Entry point address: " | sed -e "s/.*Entry point address: *//"" (procedure "run_image" line 3) invoked from within "run_image $elf_img" (procedure "run_boot_dir" line 119) invoked from within "run_boot_dir $binaries" (procedure "build_boot_image" line 2) invoked from within "build_boot_image { core init hello_client hello_server timer }" (file "/home/mark/genode_git/repos/hello_tutorial/run/hello.run" line 44) invoked from within "source $include_name" ("foreach" body line 6) invoked from within "foreach include_name [get_cmd_arg --include ""] { # first check if the include name is absolute if {[string first "/" $include_name] == 0} { puts ..." (file "/home/mark/genode_git/tool/run/run" line 636) make: *** [run/hello] Fehler 1 Without run option "include image/uboot" the build finished cleanly and image.elf was created correctly. Regards Mark
