    Disable delay on ctrl-alt-delete in vt

    Flawed or not, the delay is a (apparent) empty loop or delay call that's activated somewhere on ctrl-alt-delete. The reboot works. No keymap files are present on this system. I only want it immediate instead of after a delay. From an X graphical screen with openbox, I just added my hardreset...

    Disable delay on ctrl-alt-delete in vt

    For a custom minimal live FreeBSD system, I'm looking for a way to do a instant reboot when ctrl-alt-delete is pressed, on the vt/bash command-line. In X.org, this works without problems by setting sysctl kern.panic_reboot_wait_time=0 sysctl debug.kdb.panic=1 to simulate a panic + instant...

    Trying to capture raw USB touchscreen data

    Some years ago, I made a shell script + C program that filters data from a USB-touchscreen. It used the /usr/sbin/usbdump tool but with time delay value commented out to get real-time data. This had to be converted from hex byte pairs to decimal screen coordinates and passed to a POS-system...

    Trying to get distcc do something on 2 qemu virtual machines

    I'm trying to get distcc running to do a distributed buildworld. As a test, I installed FreeBSD 13.2 amd64 on 2 Qemu virtual machines. Both are connected to 2 tap devices in a network bridge. They can ping the host and eachother. The ip's of these machines are 192.168.2.5 and 192.168.2.7. The...

    Orange Pi Zero / how to access internal flash device

    I still have the Armbian SD-card that I used to make them bootable without SD-card. Serial works too. I will try to look up for the chip model. The /boot/dtb/overlays directory of the GENERIC-SD image seems to contain files related to this, Also, the 13.2 source contains the arm kernel config...

    Orange Pi Zero / how to access internal flash device

    I pasted that code block into a file, compiled it with dtc, copied the output file to /boot/dtb/overlays and added fdt_overlays="jedec_overlay.dtbo" to loader.conf It loads the overlay at first but then it says "not compatible". Loading DTB overlays: 'jedec_overlay.dtbo'...

    Orange Pi Zero / how to access internal flash device

    Ok, removed that line and copied the compiled dtb file over the existing one in /boot/dtb This changes nothing. Still having these boot-messages: mmc0: <MMC/SD bus> on aw_mmc1 mmc0: No...

    Orange Pi Zero / how to access internal flash device

    I decompiled /boot/dtb/sun8i-h2-plus-orangepi-zero.dtb that comes with the 13.2 GENERIC-SD release. The output is very long and totally different than the dts file with the same name in the 13.2 source, that I was trying. Next, I put in /boot/loader.conf...

    Orange Pi Zero / how to access internal flash device

    Update: After a lot of searching, I found out that I probably have to generate a new dtb (device tree blob) file because the original FreeBSD 13.2 source file /src/sys/contrib/device-tree/src/arm/sun8i-h2-plus-orangepi-zero.dts has the spi entry set on "disabled". I changed it to "okay" like the...

    FreeBSD 13.2 strange colors during kernel startup

    Those are bootloader options that assure the use of lua and not forth anymore. This is already default in FreeBSD, as far as I know

    FreeBSD 13.2 strange colors during kernel startup

    When using vt and hw.vga.textmode=0, the colors are gone. Not sure what was going on, though. Why does the kernel change output color while starting up? It looks like there's something with the ioapic init that unintentionally causes this, like palette rotation or something like that. I still...

    FreeBSD 13.2 strange colors during kernel startup

    No change without textmode value. I don't know what this is. Textmode 1? The name isn't present in /boot/defaults/loader.conf... It might be a obsoleted value that's left in my config files.

    Orange Pi Zero / how to access internal flash device

    I did all of that, including working through that Hackaday page. Later, I built the ports version of u-boot, and wrote the bin file to the SPI storage using Armbian because I can't access the device in FreeBSD. It all works except direct access to this internal storage from the FreeBSD CLI. This...

    Orange Pi Zero / how to access internal flash device

    U-boot does work with FreeBSD. In Armbian, I wrote FreeBSD's u-boot bin file to the SPI storage. If boots FreeBSD from Sd-card or remote server with no problems. Access to the device in FreeBSD is really all I need. I believe it's 16MB. Besides disk-less booting from it, it's also useful to...

    Orange Pi Zero / how to access internal flash device

    I already wrote an image to it using the recommended Armbian installation for this board. The SPI device exists and works. After making a working tftp/dhcp/nfs server, writing a bootloader to the device using FreeBSD is the last thing I need to boot a cluster of these things without SD-cards...

    Orange Pi Zero / how to access internal flash device

    Not on a GENERIC-SD system. At least, the directory doesn't exist and can't be created.

    Orange Pi Zero / how to access internal flash device

    Update: I tried the GENERIC-MMCCAM kernel version. This results in a /dev/sdda0 device, which is the same as the sd-card mmcsd0. The mmc0 device now shows different info. No "carrd not found" but it still isn't accessible by a /dev entry. aw_mmc0: <Allwinner Integrated MMC/SD controller> mem...

    FreeBSD 13.2 strange colors during kernel startup

    It cycles magenta/red/green at random kernel output lines. At the end, the cursor remains red. My loader.conf: geom_uzip_load="YES" debug.acpi.disabled="hostres" hw.syscons.bell=0 vfs.usermount=1 kern.hz=100 kern.cam.boot_delay=10000 vm.kmem_size="629145600" mfsroot_load="YES"...
