Hello,
I am able to poke around in the TorizonCore’s initramfs by using tdxargs=rdinit=/bin/sh but once I’ve reached the initramfs shell, I am unable to see a connected EXT4 SATA SSD to then switch_root to. I tried
cat /proc/partitions; blkid; parted -l; dmesg | grep sata; dmesg | grep ahci; df; modprobe ahci; fdisk -l
and every other command I could think of. I am building Torizon in Yocto.
Greetings @jonk4m,
There’s a couple of factors here. First of all when you first get into the initramfs shell nothing is setup and /dev is probably not populated with any devices. If you look at the script /init it should look something like this: https://git.yoctoproject.org/poky/plain/meta/recipes-core/initrdscripts/initramfs-framework/init
Normally this script is ran automatically but since you interrupted the process to get into the shell it never ran, therefore nothing is setup. You can look through the script to see how it sets up the initramfs environment for booting. One of the things this script does is populate /dev based off devtmpfs. I did a quick test and after I manually performed this I was able to see the mmc devices and my attached USB device in /dev.
Now what I’m unsure of is whether this is all that is needed for your SATA SSD. Your device may need an additional driver for it to be instantiated. I don’t have a SATA SSD lying around to test only some SD cards and USBs. These were properly instantiated in the initramfs environment without having to do anything special. If a driver is needed you may need to customize the default initramfs to include the required driver as a kernel-module.
Best Regards,
Jeremias
Running the init script allowed me to view connected devices with /dev populated like you said. I was able to see a USB drive and SD, but not the SATA drive. If you could point me in the direction of the required kernel-module to include, that’d be a big help, thanks!
I was able to see a USB drive and SD, but not the SATA drive.
Hmm that’s what I feared. Well the kernel driver/module you need would be the same as in Linux. I believe that’s the “ahci-imx” driver. There should be a way in Yocto to select and build kernel modules into the initramfs. Though mind you I’m making a bit of an educated guess here rather than reciting something I’ve done myself.
Once initramfs has the kernel module that gives it the capability to mount and use SATA drives I would hope then that this would be enough for your device to be seen in initramfs.
Best Regards,
Jeremias
I still have not managed to see the SATA device from the initramfs. I tried adding:
KERNEL_MODULE_AUTOLOAD += " ahci-imx"
PACKAGE_INSTALL_append = " \
kernel-modules \
ahci_platform \
nano \
parted \
i2c-tools \
dosfstools \
e2fsprogs-mke2fs \
parted \
udisks2 \
run-postinsts \
"
to my local.conf, with the same disappointing results. How exactly would I add SATA support to the Torizon initramfs, whether bundled or not?
@jeremias.tx I was able to see the SSD via changing the kernel configuration as described here, on page 79.
However, I get the follow when I try to switch_root to the Torizon rootfs on the SSD:
sh-5.0# exec switch_root -c /dev/console /rootfs /sbin/init

Do you have any idea what issue this might indicate?
After having your SSD be seen in /dev, did you call switch_root immediatel right after?
Initramfs after calling the init script calls several other scripts located in /init.d/* that do further things to prepare the system for booting to Linux proper. The scripts are pre-pended by numbers indicating what order the are executed in. If you didn’t execute these scripts or their equivalent steps the system might be left in a state where it’s not ready to boot yet.
I’d suggest studying these scripts to see how your SATA based boot flow fits in to them. Probably only the rootfs script needs to be looked at, but make sure to check the other just in case.
