BBC Basic binary for Genode / armv8
by Michael Grunditz 04 May '23

04 May '23

Hello Genodians, I have added a BBC Basic binary to my genode-rockchip gitbub repo [1]. Put it in your build/armv8_a/bin directory. I don't have any ready to use run files. You need to run the terminal scenario and make sure that stdout/in is to the terminal. The reason for not doing source upload is that the build system for it is broken. This will change in the future. The status for my RISC OS / Genode project is that I am prototyping the cpu emulation layer on pc/linux. Right now I can boot RISC OS and run some simple commands. The main issues on a target system is to get interrupts to the emulation from hardware. I think that I can map up the GIC without much problems, but the GIC will interrupt the cpu that runs the emulation. It will be a slight an adventure to get it into the emulation! Have fun with basic , tell me if you can use it! Michael [1] https://github.com/mickenx/genode-rockchip/tree/main/bin/armv8a

Other filesystems in Genod/Sculpt OS
by reza.fathzadeh＠yahoo.com 02 May '23

02 May '23

Hi everyone, Would filesystems other than EXT2 be supported in Genode/Sculpt OS? And if so, is there a roadmap/timeline? I find EXT2 (even EXT3/4) quite limiting. Thank you,Reza

Dear folks, Last time that I flashed the pinephone image of genode, it was only working for sd card and not for eMMC. Does it now work for eMMC? Thanking you Sagar Acharya https://designman.org

Minor problem with bin/src archive
by Martin Stein 25 Apr '23

25 Apr '23

I was just fixing a problem with the old file vault for Sculpt 23.04 and wanted to try it with the file_vault run script (with --depot-auto-update) when I ran into an issue I did not have before my fix but that was totally unrelated to my fix: ! [init -> file_vault -> vfs_block] Error: LD: symbol not found: 'typeinfo for Genode::Console' ! [init -> file_vault -> vfs_block] Error: Uncaught exception of type 'Linker::Not_found' I couldn't figure out where it came from and it stayed also after 'make clean'. Finally, I could fix it by removing both my vfs_block src and bin archives (so, they got rebuilt). Vfs_block has LIBS += base in its target.mk and the file vault pkg has vfs_block in its archives and <content/> tag. Its not critical for me but I thought it would be worth mentioning it. Cheers, Martin

PinePhone image 2023-04-06 (wifi, software-add tab, Jitsi preset)
by Norman Feske 24 Apr '23

24 Apr '23

Dear PinePhone users, I have just published a new Sculpt image for the PinePhone today: https://depot.genode.org/nfeske/image/ The new version 2023-04-06 introduces three new features: 1. Wifi! For those of you without mobile data connectivity, you can now select "Wifi" in the network part of the GUI, select an access point and enter your passphrase, just like on the PC version of Sculpt. Since the passphrase is not saved, you have to enter it each time when connecting. Not a bug. It's for training your blind typing skills. ;-) ...don't worry, those usability topics are on our list. 2. There is a new preset that starts a pre-configured Morph browser right into Jitsi alongside the camera driver. Speaking of the camera, it is now operated in gray scale because we found the colors provided by the sensor not really presentable. Later, we may come back to work on the colors but until then, gray-scale looks nice enough. When asked, select "Use Jitsi on the Website". As of now, the preset is mainly intended to ease the testing of further performance optimizations. It may not by suited for practical use yet, but I think its a good time to show how far we have come already. 3. The new "Add" tab in the Software section provides the functionality of Sculpt's '+' menu, which is the browsing of depot menus, the installation of packages, and the manual deployment of new components. In addition to regular Sculpt, it offers a way to directly add URLs of new software providers. Since Sculpt does not know any public keys of such providers, downloads can of course not be verified. But the system still offers you the option to download packages without verification. The assessment of trust in such components is of course entirely up to you. Installation - If you have an earlier version of Sculpt installed and a mobile data connection, you can use the "Update" tab in the software section of the GUI to check for updates from 'nfeske', download the '2023-04-06' image, press the install button, and reboot. You may chose to also download an older image (without install). So you can always switch back to the old version should the new image not be to your liking. - For preparing a fresh SD-card, please follow the instructions as given in the first announcement: https://genodians.org/nfeske/2023-02-01-mobile-sculpt Have fun with trying out the new image!

Dear Genodians, The java.run for arm_v7a script was executed successfully and the log output is attached below. I have java program, // This is a simple Java program. // FileName : "HelloWorld.java". class HelloWorld { // Your program begins with a call to main(). // Prints "Hello, World" to the terminal window. public static void main(String args[]) { System.out.println("Hello, World"); } } I want to run the above code on genode sculpt, can you guide us to execute it. -- Regards, Devashish Dewangan CS21M017

Avoiding fetchurl restarts
by Timo Nicolai 19 Apr '23

19 Apr '23

Dear Genodians, I have noticed that at least when running on Linux, the fetchurl component started by depot_download_manager will always restart immediately after it is first executed (before anything has been downloaded). After that the download proceeds as normal. This is because Fetchurl_watchdog uses trigger_periodic to trigger the timer handler which checks the current download progress. As a consequence, this handler /might/ be called immediately, before fetchurl has had the chance to do any work. I believe this is a bug, but one that might not manifest on all platforms due to the uncertain timing introduced by trigger_periodic. I have attached a potential patch, if this sounds okay to you I will open an Issue on GitHub. Best regards, Timo -- Timo Nicolai Operating Systems Engineer Gapfruit AG Baarerstrasse 135 6300 Zug - Switzerland timo.nicolai(a)gapfruit.com https://gapfruit.com

Request for testing: updated ported Intel display driver
by Alexander Boettcher 19 Apr '23

19 Apr '23

Hello, currently we are testing our updates of ported Linux drivers [0] on various generations of Intel hardware. The available test hardware in the lab works fine, so far, but we can't be sure whether it applies to all systems out there. You may support us, and thereby the next Sculpt release, by test driving the prepared images. The images are bootable via USB stick and can be prepared similar as documented for Sculpt [2]. With the tests by you, we may detect regression earlier, e.g. before the Sculpt release. The test is very simple (and not sensational at all) and cycles through some test pictures. When external monitors are attached, the test pictures are mirrored across all connectors. The resolution changes automatically to the largest resolution available, so that monitors with smaller resolution will just show a part of the test picture (so, it is expected behavior). Image [3] contains the driver based upon Linux kernel 6.1 as be part of Genode staging branch. Image [4] is a variation, which tries to use more of the drm/kms interfaces [2] (and is still work-in-progress). Ideally, both just work. Please also try to attach/detach connectors multiple times to stress the driver a bit. If [3] and [4] does not work (or one of them), it would be nice, to give the 5.14. based driver [5] a spin. With this information we can see, whether it never worked on your system or it is really a regression due to the update to 6.1. If it works for you, it would be good to know about. If it does not work, it would be even better to know about. In both cases, the specification of your hardware would be appreciated. If you don't want to spread the information publicly, you may also write me a direct message. Luxurious support would be, if you can send a captured trace via uart/serial/amt [6] in case something does not work for you. Please send captured logs directly to me, just to avoid spamming the mailing list. Thanks for your support & have a nice Easter, Alex.
