Hi ARM guys!
I think current openQA AArch64 tests are done using qemu (at least virtualization).
Correct, and even they keep failing :).
But, how far is ARM tests on real hardware? It seems os-autoinst support real hardware and I remember that some people worked on it during hackweeks.
Are you interested in embedded or server style hardware? For server style hardware with proper BMC, I don't think there'd be much apart from hardware availability keeping us from doing it. For embedded style hardware, the biggest hurdle is that we need to test JeOS images rather than the installation, because we need to provide firmware as well.
I have only embedded style boards here, no BMC server. ;) Indeed, the idea is to test JeOS images.
I would like to collect all information in order to maybe work on it a bit. For example, which devices do you use to power on/off boards. Did you use os-autoinst or some other tests tools?
One thing I've been working on is an SD card simulator using the BBB. Unfortunately my EE skills are abysmal, so I get up to the point where the SD host switches to 25Mhz mode and then the line collapses ;).
Can you send me details about what you did and what worked/failed, please?
I wrote PRU programs that handle the SD traffic and route read/write operations to Linux. It's all based on the new remoteproc stuff that TI is working on (but hasn't upstreamed yet fwiw).
The main problem I think it the wiring. I currently have free floating cables from the SD slot of a rpi3 to the pins of my BBB. Instead, I probably just need to design a PCB to route things properly and invest a few more weeks into making the PRU and Linux host code fully stable ;).
Interesting. Do you have some code available (github or something)?
With a working SD card simulator, remote power / reset GPIO, an HDMI frame grabber and USB OTG for keyboard/tablet simulation, we should be able to create a generic OpenQA test bed for any embedded device out there.
A remote power (or reset) should not be too difficult to buy or build. Have you some working around?
I have remote power switches around and there is also always the CPU reset line on the ARM JTAG interface that you can probably just wire up using GPIOs on an ARM system.
Remote power switches are hand made or from reseller? If you have any good item, please share the name.
A HDMI frame grabber could be replaced with a serial link as a first step, maybe?
I have an HDMI USB3 frame grabber around as well ;). But yes, serial is another option.
Some USB work has been done by someone (Bernhard Wiedemann?) during hackweek (2015?), if I remember correctly.
Yes, it's pretty straight forward. All the components are in Linux already.
Is there any repo where we can get code or build step, configs, or something? Guillaume
