Hello,
In our last meeting on May 17 it was mentioned that there was work being done on the Lantronix device tree and it was booting in 6.4(? I think that was the version) kernel.
How's work on porting to 5.15 going? Is there a way to get the 6.4 kernel and the device tree to test out the booting locally for us?

Hi Patrick,
I'm working on a device tree for Open-Q 865 that is based on the current arch/arm64/boot/dts/qcom/qrb5165-rb5.dts upstream in 6.4-rc1. I should have a basic bootable device tree ready for you to test by our next meeting on May 31. I'll also rebase a version on 5.15 so you can try that as well (qrb5165-rb5 device tree works on 5.15 so I don't anticipate any issues for the open-q 865).

Hi Patrick,
Here's an an initial commit for the Lantronix Open-Q 865 devkit that gets it booting up to a console (albeit with a very spare DTS): https://git.codelinaro.org/william_gray/openq-865/-/commit/42f82bde586fd1c33...
The main files of interest are *openq5165rb.dtsi *which serves as an include for the the QRB5165RB SOM, while the *qrb5165-lantronix-openq865.dts* is the main DTS for the board. I based this around the definitions for the qrb5165-rb5 which is mostly compatible; I'll be making adjustments throughout to fit the openq865 more aptly (e.g. defining a pm8250 based on the existing pm8150 nodes).
You can follow my v5.15 development here: https://git.codelinaro.org/william_gray/openq-865/-/tree/openq865-v5.15

Vinod wrote a great blog post detailing how to boot the mainline kernel on Qualcomm devices: https://www.linaro.org/blog/let-s-boot-the-mainline-linux-kernel-on-qualcomm...
Here's a summary of the commands I execute on my ARM64 Linux dev PC to boot the Open-Q 865 with the new device tree:
# make defconfig # make Image.gz dtbs modules # make modules_install INSTALL_MOD_PATH=./modules_dir INSTALL_MOD_STRIP=1 # cat initramfs-test-image-qemuarm64-20230321073831-1379.rootfs.cpio.gz modules.cpio.gz > final-initramfs.cpio.gz # cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/qrb5165-lantronix-openq865.dtb > Image.gz+dtb # CMDLINE="ignore_loglevel earlycon" # git clone https://git.codelinaro.org/clo/qsdk/oss/tools/skales --depth=1 # python2 ./skales/mkbootimg --kernel Image.gz+dtb --cmdline ${CMDLINE} --ramdisk final-initramfs.cpio.gz --base 0x80000000 --pagesize 4096 --output boot.img # fastboot boot boot.img

Hey William,
In terms of testing this. What filesystem image were you using? Did you start from a Linaro based complete build like the existing yocto build environment on the 96boards for the RB5? Or did you start with the latest Lantronix BSP release and then just build this kernel and then flash the boot.img to that?
I just want to make sure that we are starting from the same place.

Hi Patrick,
I just used the latest Lantronix BSP release preinstalled on the board as the filesystem base. The initramfs cpio test image came from Linaro here: https://snapshots.linaro.org/member-builds/qcomlt/testimages/arm64/1379/init...
I hope that helps answer your questions.

I just used the latest Lantronix BSP release preinstalled on the board as the filesystem base. The initramfs cpio test image came from Linaro here: https://snapshots.linaro.org/member-builds/qcomlt/testimages/arm64/1379/init...
I hope that helps answer your questions.

In terms of testing this. What filesystem image were you using? Did you start from a Linaro based complete build like the existing yocto build environment on the 96boards for the RB5? Or did you start with the latest Lantronix BSP release and then just build this kernel and then flash the boot.img to that?
I just want to make sure that we are starting from the same place.

Hi William,
I was messing around with loading the kernel and taking a look at the system. And I just noticed that I don’t have access to the root filesystem from the Lantronix BSP when I boot from the Linaro kernel and device tree you have provided.
Is this because of device tree work? Or does this have to do with initialization and the boot.img that I created using the initramfs? If it is because of the boot.img I want to start making progress on getting that fixed but I wasn’t sure or not.
As a side note: I noticed the kernel command line option “skip_initramfs” was there when I booted from the linaro kernel boot.img that I created using the instructions you provided. Is that correct?
Thanks!

Hi Patrick,
That's normal, I haven't yet completed the storage nodes for the device tree so we're not able to access the filesystem just yet. Regarding `skip_initramfs`, where did you come across it; are you seeing it in /proc/cmdline?

Hi Patrick,
I just used the latest Lantronix BSP release preinstalled on the board as the filesystem base. The initramfs cpio test image came from Linaro here: https://snapshots.linaro.org/member-builds/qcomlt/testimages/arm64/1379/init...
I hope that helps answer your questions.

I was messing around with loading the kernel and taking a look at the system. And I just noticed that I don’t have access to the root filesystem from the Lantronix BSP when I boot from the Linaro kernel and device tree you have provided.
Is this because of device tree work? Or does this have to do with initialization and the boot.img that I created using the initramfs? If it is because of the boot.img I want to start making progress on getting that fixed but I wasn’t sure or not.
As a side note: I noticed the kernel command line option “skip_initramfs” was there when I booted from the linaro kernel boot.img that I created using the instructions you provided. Is that correct?

Ah, this line tells the system to skip loading the initramfs from the boot partition on the filesystem. We're bypassing the filesystem by using fastboot to directly load the kernel and initramfs so that `skip_initramfs` line does not affect us. Later when we get storage support working, we'll put our initramfs cpio file in the boot partition and load it from there, but for now you can safely ignore that line.

Later when we get storage support working, we'll put our initramfs cpio file in the boot partition and load it from there, but for now you can safely ignore that line.

Would you like me to check the /proc/cmdline also?

Hi Patrick,
That's normal, I haven't yet completed the storage nodes for the device tree so we're not able to access the filesystem just yet. Regarding `skip_initramfs`, where did you come across it; are you seeing it in /proc/cmdline?

I was messing around with loading the kernel and taking a look at the system. And I just noticed that I don’t have access to the root filesystem from the Lantronix BSP when I boot from the Linaro kernel and device tree you have provided.
Is this because of device tree work? Or does this have to do with initialization and the boot.img that I created using the initramfs? If it is because of the boot.img I want to start making progress on getting that fixed but I wasn’t sure or not.
As a side note: I noticed the kernel command line option “skip_initramfs” was there when I booted from the linaro kernel boot.img that I created using the instructions you provided. Is that correct?
Thanks!

Hey Patrick,
That's great to hear you were able to boot! Since we're both able to run on 6.4 now, I'll continue development on this branch (openq865) so we're on the latest and greatest.

Hi William,
I tested the 5.15 branch that you sent over. I was able to boot to command line like expected. Below is the output from the 3 locations for versions that I know of.
root@qemuarm64:~# uname -a Linux qemuarm64 5.15.54-00001-g42f82bde586f #2 SMP PREEMPT Thu Jun 1 14:11:30 PDT 2023 aarch64 GNU/Linux root@qemuarm64:~# cat /etc/version 20180309123456 root@qemuarm64:~# cat /proc/version Linux version 5.15.54-00001-g42f82bde586f (slroot@PDXPWHEWELL) (aarch64-linux-gnu-gcc (Ubuntu 9.4.0-1ubuntu1~20.04.1) 9.4.0, GNU ld (GNU Binutils for Ubuntu) 2.34) #2 SMP PREEMPT Thu Jun 1 14:11:30 PDT 2023
It looks like this is the location for the 6.4 kernel https://git.codelinaro.org/william_gray/openq-865/-/tree/openq865
I will attempt to build/boot using this next and send you an email with the results.

Hi Patrick,
I just used the latest Lantronix BSP release preinstalled on the board as the filesystem base. The initramfs cpio test image came from Linaro here: https://snapshots.linaro.org/member-builds/qcomlt/testimages/arm64/1379/init...
I hope that helps answer your questions.

In terms of testing this. What filesystem image were you using? Did you start from a Linaro based complete build like the existing yocto build environment on the 96boards for the RB5? Or did you start with the latest Lantronix BSP release and then just build this kernel and then flash the boot.img to that?
I just want to make sure that we are starting from the same place.

Vinod wrote a great blog post detailing how to boot the mainline kernel on Qualcomm devices: https://www.linaro.org/blog/let-s-boot-the-mainline-linux-kernel-on-qualcomm...
Here's a summary of the commands I execute on my ARM64 Linux dev PC to boot the Open-Q 865 with the new device tree:
# make defconfig # make Image.gz dtbs modules # make modules_install INSTALL_MOD_PATH=./modules_dir INSTALL_MOD_STRIP=1 # cat initramfs-test-image-qemuarm64-20230321073831-1379.rootfs.cpio.gz modules.cpio.gz > final-initramfs.cpio.gz # cat arch/arm64/boot/Image.gz arch/arm64/boot/dts/qcom/qrb5165-lantronix-openq865.dtb > Image.gz+dtb # CMDLINE="ignore_loglevel earlycon" # git clone https://git.codelinaro.org/clo/qsdk/oss/tools/skales --depth=1 # python2 ./skales/mkbootimg --kernel Image.gz+dtb --cmdline ${CMDLINE} --ramdisk final-initramfs.cpio.gz --base 0x80000000 --pagesize 4096 --output boot.img # fastboot boot boot.img

Here's an an initial commit for the Lantronix Open-Q 865 devkit that gets it booting up to a console (albeit with a very spare DTS): https://git.codelinaro.org/william_gray/openq-865/-/commit/42f82bde586fd1c33...
The main files of interest are openq5165rb.dtsi which serves as an include for the the QRB5165RB SOM, while the qrb5165-lantronix-openq865.dts is the main DTS for the board. I based this around the definitions for the qrb5165-rb5 which is mostly compatible; I'll be making adjustments throughout to fit the openq865 more aptly (e.g. defining a pm8250 based on the existing pm8150 nodes).
You can follow my v5.15 development here: https://git.codelinaro.org/william_gray/openq-865/-/tree/openq865-v5.15

I'm working on a device tree for Open-Q 865 that is based on the current arch/arm64/boot/dts/qcom/qrb5165-rb5.dts upstream in 6.4-rc1. I should have a basic bootable device tree ready for you to test by our next meeting on May 31. I'll also rebase a version on 5.15 so you can try that as well (qrb5165-rb5 device tree works on 5.15 so I don't anticipate any issues for the open-q 865).

In our last meeting on May 17 it was mentioned that there was work being done on the Lantronix device tree and it was booting in 6.4(? I think that was the version) kernel.
How’s work on porting to 5.15 going? Is there a way to get the 6.4 kernel and the device tree to test out the booting locally for us?
