Dear Tomasz, Apologies for the delay in getting back to you. I appreciate your efforts. Thanks so much for your help. I can see the runtime log on Rpi3 B+ !
Thanks Alexander Weidinger for his help. Adding the three lines on config.txt will work ! I didn't use u-boot, I just used bootcode.bin (rpi website provided). Now, I could go ahead to do experimenting with Rpi 3 B+ But recently I faced some problems. It's about how to write the system configuration. Although I tried to solve it according to the runtime logs, finally I still failed... I wrote a new letter. The title was "Can QT-based "textedit" run successfully on Rpi 3 B+ ?" Thank you. 😊 Tomasz Gajewski <[email protected]> 於 2019年7月5日 週五 下午7:50寫道： > kimberly nNA <[email protected]> writes: > > Hi, > > > I modified and added some apps on demo.run > > The genode version is > https://github.com/tomga/genode/tree/rpi3bplus_19.02 > > It's great that someone tries to use this :-). > > > I tried this commands : > > $ ./tool/create_builddir rpi3bplus > > $ make run/demo KERNEL=hw > > This case successfully run on Rpi3 B+ > > It's even more great to hear that it is working. > > > But I couldn't see the runtime log like as on x86_64 : > > > ---------------------------------------------------------------------------------- > > ... > > [init -> drivers] Error: Could not open ROM session for "config" > > [init -> drivers] Error: Uncaught exception of type > 'Genode::Rom_connection::Rom_connection_failed' > > [init -> drivers] Warning: abort called - thread: ep > > [init] child "drivers" exited with exit value 1 > > [init -> acpi_drv] Found MADT > > ... > > > ----------------------------------------------------------------------------------- > > Like the above example, sometimes I want to debug errors on Rpi. > > Can I see the runtime log on Rpi3 B+ ? > > If it can, how to set on putty ?
