Is there a way like on the Odroid boards to choose to always boot from the micro SD?
Having to press on the USR button is not practical. I want to use a 64GB or 128GB device for my gentoo Linux. One nice thing about the beagleplay though is that unlike with beaglebone AI-64 the HDMI output works.
Ideally I would have EFI where I could set multiple boots like I do on my PC. I don’t see any documentation on how to setup beagleplay for EFI boot with grub.
On my PC I have mint as the first boot which I rarely use. I have it as a backup in case I mess up on gentoo or arch linux.
With grub on mint I set gentoo as the default boot.
On my system I have Mint, gentoo and arch linux. I do have ubuntu and newer OS/2 on VirtualBox.
On the Beaglebone Black I was using a gpio pin to force a boot on the micro SD.
I actually didn’t need to do that, so the instruction about having to use the USR button is incorrect. It seems like the SD card has priority.
To create my image I cheated. I copied the official beagleplay image and replace the boot files and rootfs with the ones I created.
It worked perfectly except for a weird issue.
I have it connect to an ACER HDMI portable monitor (around 12 inch)
I use the mate desktop.
I have a usb to serial cable I got from Digi-key for debugging, I made an adapter with a ElectroCookie board .
I was compiling the support files so I can compile Filezilla using ssh and all of a sudden the display on the screen went out. The screen was black. I was not able to get it out of that mode. I did have the screen saver disabled but not the other power saving crap.
I am assuming that it thought that the system wasn’t use so it went into some sleep mode.
Compiling still worked for a while, I could even type something on the serial debug (I use PuTTY)
After a while the whole thing was frozen. To recover I had to disconnect the power and power the board back.
What could be the cause and then what would be the solution if any?
I have disabled the power saving mode, it hasn’t crashed again yet which doesn’t mean that it won’t in the future.
No log. After this event I checked and saw that power save was still enabled so I set it to never and the problem never came back.
I am assuming that the mate desktop power save did the trick but it was not possible to wake up. On gentoo on my Ryzen computer all I have to do is move the mouse of press on a key on the keyboard.
I do use the logitech keyboard that can connect to 3 computers. I got it at a time because it supports the mac as well. Due to some annoying bugs I ended up using a separate keyboard for my mac studio.
I find out that it is not only on the mac that it sometimes screws up. On gentoo yesterday I meant to delete on a directory everything that ended up with ~ using rm *~ but it actually typed *;
On the French Canadian keyboard I use the altgr for the third keypad entry. On the mac the windows and alt keys are swapped. The alt key becomes the cmd key and the windows key becomes the opt key.
The reason for that problem is that the keyboard for some weird reason switched to mac mode.
Luckyly I have linux rm set to always ask before actually making the delete. For some bizarre reason a delete like that never asks for confirmation by default.
Is it possible that the kernel stop recognizing the keyboard and mouse when switched to another computer for a while? As to why it shutdown after a while is a mystery since it was busy on the ssh connection.
I think that this keyboard is junk but at the price I paid for it I can’t just throw it in the trash yet.
I have finished my tests and completed the documentation on creating a gentoo on the gentoo wiki. My next step is to create a gentoo without a desktop, one that just runs a CAN program. I connect a small LCD and CAN driver on the mikro bus connector.
