![]() So for each of my devices ( sda through sdd), I ran fdisk to create one primary partition: $ sudo fdisk /dev/sda but there are a couple small reasons it seems safer that way. Technically it's not required to partition before creating the array. how is there also an NVMe drive there?! Well, I'm also testing some PCI multi-port switches with the Pi-follow that issue for progress.) Partition the drives with fdiskįor each of the drives that were recognized, if you want to use it in a RAID array (which I do), you should add a partition. Once that's done, you should be able to see any drives attached to the card after boot using lsblk, for example: $ lsblk I have full directions for recompiling the kernel with SATA support on the Pi itself, too! Raspberry Pi OS (and indeed, any OS optimized for the Pi currently, like Ubuntu Server for Pi) doesn't include all the standard drivers and kernel modules you might be used to having available on a typical Linux distribution.Īnd the SATA kernel modules are not included by default, which means the first step in using a PCIe card like the IO Crest (which has a Marvell 9215 chip-which is supported in the kernel) is to compile (or cross-compile, in my case) the kernel with CONFIG_ATA and CONFIG_SATA_AHCI enabled. * Create the following Makefile in the same directory as the xpad.The rest of this blog post will go through some of the details for setup, but I don't have the space in this post to compile all my learnings here-check out the linked issue and video for that! Getting the SATA card working with the Pi There is probably a better way to specify this define. * I patched the xpad.c to get the leds to stop blinking by adding "#define CONFIG_JOYSTICK_XPAD_LEDS" to right below #include's. However, I chose to download the xpad sources from the official Linux Kernel repository to get the latest and greatest xpad source that contains support for a couple of more devices: To get the leds from stop blinking, read more below. The source for xpad is there as well and the needed xpad.ko can be built by running "make SUBDIRS=drivers/input/joystick modules CONFIG_JOYSTICK_XPAD=m" from the /usr/src/raspberrypi-linux-* directory. * ln -s `pwd` /lib/modules/`uname -r`/buildĪfter the above steps, you should have the whole kernel tree in /usr/src that was needed to prepare the kernel headers. Here are my steps for getting the kernel headers based on the above link: Surprisingly, raspbian does not seem to include any packages for the kernel modules or the headers needed to build your own modules. If you're interested, here are the technical details on how I built the kernel module.įirst step is to get the kernel headers. In case you don't know, "apt-get install joystick" to get the jstest program and run "jstest /dev/input/js0" to make sure it works. ![]() Make sure the gamepad shows up under /dev/input, for example, as /dev/input/js0. I also added the command to /etc/rc.local so it loads automatically during boot. It is attached to this message, just download the file somewhere, gunzip it and run the command "insmod. It's not included with the raspbian modules for some reason so I just compiled it last week. ![]() I just use the standard kernel module named "xpad" with my wired Microsoft Xbox 360 USB controller.
