First system image of Sculpt OS for the PinePhone
Hello, I'm happy to announce the first system image of Sculpt OS for the PinePhone: https://genodians.org/nfeske/2023-02-01-mobile-sculpt Thanks to the wonderful team at Genode Labs for having made that possible! Speaking for myself, I'm overjoyed. :-) BTW, I will present this version on Saturday at FOSDEM in Brussels: https://fosdem.org/2023/schedule/event/genode_on_the_pinephone/ For the immediate testing period at the current stage, I am mostly interested in the operation of the modem and the overall robustness. Hence, I would appreciate your responses with testing mobile-data connectivity and voice calls as well as reporting of glaring bugs or annoyances. Regarding the use as daily driver for me personally, I see two blocking issues, which I will tackle next. - A sleep mode that turns off the screen after a few seconds of no interactivity. I think with this change, one battery charge could get us through the day. - A prolonged standby mode that switches off the application processor and keeps the SCP watching the modem for incoming calls and booting the application processor on such events. This will ultimately allow us stay receptive for incoming calls for several days without recharging. Should you like to experiment with building / experimenting / modifying the system, please share your rough direction so that I can supplement further documentation to support you. Wishing you fun with trying out Sculpt OS on the PinePhone! Norman -- Dr.-Ing.

Running genode on QEMU having board support of raspberry pi for arm_v8.
Dear genodians, As I saw that you already worked on the Raspberry for Genode framework,I wanted to ask about that because I am also working on it. I am trying the port genode having the arm_v8a support of Raspberry board to run that on QEMU. So I need some guidance from you on how to start and what should be the roadmap for generating the boot image (.img file ) having arm 64 architecture which can be booted and run on QEMU. It would be very helpful for me if you guide me to port genode on QEMU for arm_v8a. Regards, DHIRAJ. ___ Genode users mailing list users@lists.genode.org https://lists.genode.org/listinfo/users

You can also send the output here and I will have a look. I will check that and send you the output, if necessary.

These are some very old issues (2011). Could you let me know how to reproduce
this?
The Goa project can be found as follows:
- repository: g...@github.com:trimpim/wasmedge-genode.git
- branch: llvm-arm_v8a_failure
For Goa to build libraries the following version is required:
- repository: g...@gitlab.com:/gapfruit-community/goa.git
- branch: library_support
This, I could not find and used the one from GitHub.
In the llvm directory execute the following commands:
```
goa build-dir
goa build
```
In theory `goa build` should suffice, but for some reason this fails with some
compiler errors. As it works by issuing the commands separate, I did not
investigate further.

up first in the DYNAMIC segment. Can you please check if it works for you?
