SK-AM62: Hypervisor AM62X SK-EVM

Hi Andreas,

       Your sending link is error.attached the image below.

Please refer to the below "Jailhouse Hypervisor" section in the Linux SDK documentation:

https://software-dl.ti.com/processor-sdk-linux/esd/AM62X/09_00_00_03/exports/docs/linux/Foundational_Components/Hypervisor/Jailhouse.htm

Hi Andreas,

 Jailhouse example is working fine. how to change custom image file i load and check some error is coming how to fix this error. I attached the screenshot below:

Thanks Regards,

Ah ok I see. Looking at your error it looks like the kernel is not able to mount the rootfs, which is a common issue when things are not configured properly. What are you trying to use for your rootfs (how did you build that custom image?)

The included linux-demo.sh example startup script expects loading a specifically-named ramdisk image out of the /boot partition from the SD card.

1. Please double check the ramdisk image name in the linux-demo.sh script matches the ramdisk image you are trying to load
2. The ramdisk image is expected to be in .cpio format. Can you double-check that you are in fact feeding it a cpio-formatted image? There are steps on how to create a cpio-formatted image documented in the "Overview" section of this E2E FAQ here: https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1176944/faq-linux-how-to-boot-sitara-am3x-am4x-am6x-devices-from-initramfs-cpio-archive-ram-disk

Hi Andreas,

I trying so many times it 's showing error . I check internet connection also good. how to fix this error i attached the screenshot.

Thanks Regards,

Veerapandiyan V.

Could be your TFTP server or network is not setup correctly or has some issue.

How large is the file you are trying to transfer?

For testing purposes, can you try transferring a small file (just a couple of KB's)?

Regards, Andreas

Hi Andreas,

I referred this link https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1259528/faq-sk-am62-how-to-build-initramfs-into-kernel-image to generate kernal image

Update kernel image to SD card

- Create a bootable SD card using the WIC image provided in the SDK. Recommended to use tisdk-base-image-am62xx-evm.wic.xz because its size is smaller.
- Mount the SD card to the Linux PC, assuming the mounting point is <SD-card-mounting-point>.
- Copy kernel image to the boot/ folder in the SD card root partition:

$ sudo cp board-support/linux-<version/arch/arm64/boot/Image <SD-card-mounting-point>/boot/Image-initramfs
$ cd <SD-card-mounting-point>
$ sudo ln -sf Image-initramfs Image

this location i changed properly. and .cpio file also added previous .cpio file removing. After i change /usr/share/jailhouse/linux_demo.sh file edit to change the my cpio file name after i booting comming some error below:

/usr/share/jailhouse/linux-demo.sh

This is just an arbitrary filename used in the https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1176944/faq-linux-how-to-boot-sitara-am3x-am4x-am6x-devices-from-initramfs-cpio-archive-ram-disk E2E FAQ that indicates the file is a Kernel image with built-in intramfs image (that was included via CONFIG_INITRAMFS_SOURCE). It is the same thing that the other E2E FAQ at https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1259528/faq-sk-am62-how-to-build-initramfs-into-kernel-image refers to as Image-initramfs. The latter E2E FAQ is just describing the steps needed for generating such an image in a bit more detail.

Regards, Andreas

Hi Andreas,

 I build kernal image after copy sd card rootfs location boot folder i paste the Image-initramfs file. address how to add address tell me.

1. Edit linux-demo.sh this format is correct or not tell me.

You can see the location of that dtb file in the very linux-demo.sh script you posted, and you can double check that it indeed exists as follows:

root@am62xx-evm:~# ls -al /usr/share/jailhouse/inmate-k3-am625-sk.dtb
-rw-r--r-- 1 root root 3289 Mar  9  2018 /usr/share/jailhouse/inmate-k3-am625-sk.dtb

Then, after copying that file to your PC, you can update it as follows:

# De-compile device tree blob (dtb) into device tree source (dts) file
$ dtc -I dtb inmate-k3-am625-sk.dtb -o inmate-k3-am625-sk.dts

# Use your favorite editor to remove the two 'linux,initrd-*' lines
$ vim inmate-k3-am625-sk.dts

# Re-compile dts file back into a dtb file
$ dtc -I dts inmate-k3-am625-sk.dts -o inmate-k3-am625-sk-new.dtb

Then copy the new dtb file back to your embedded board, and use that for jailhouse.

veerapandiyan v said:

Edit linux-demo.sh this format is correct or not tell me.

You'd want to remove the cpio image from the script (together with its address parameter that follows), and _replace_ the 'Image' file with your own. Like this...

jailhouse cell load k3-am625-sk-linux-demo /usr/libexec/jailhouse/linux-loader.bin -a 0x0 -s "kernel=0xe0200000 dtb=0xe0000000" -a 0x1000 /boot/Image-initramfs -a 0xe0200000 /usr/share/jailhouse/inmate-k3-am625-sk.dtb -a 0xe0000000

The reason for that is because you built the kernel and the initramfs into a new monolithic image, which of course will replace the original kernel that was specified on the command line.

Hi Veerapandiyan,

I'm currently tied up some some other work items I need to finish first, so it'll take me a few days before being able to look into this again. Please ping me next week in case I haven't been able to respond until then.

Regards, Andreas

Hi Andreas,

Ok. I will Wait.

Thanks Regards,

Veerapandiyan V.

Will look at this again this week, stay tuned.

Hi Andreas,

Ok. I will Wait.

Hi Andreas,

              I need emergency of hypervisor help me andreas. so i taking more times in hypervisor i want to closing two days help me.

I remember my primary os is jailhouse.

I change the secondary os is Linux RT default Image how to change so answer me.

Thanks Regards,

Hi Veerapandiyan,

I reviewed your steps and don't see anything immediately wrong with them.

However since the error you get is a "JAILHOUSE_CELL_LOAD: Invalid argument", it seems like there's something wrong with your combined Kernel + initramfs "Image" file. I also see it is over 800MB in size, which is  extremely large. How did you build this Image file? You should start building a much smaller filesystem into the Kernel, based off the tisdk-tiny-image-* filessytem that comes with the SDK, as per https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1259528/faq-sk-am62-how-to-build-initramfs-into-kernel-image

Once you build a tisdk-tiny-image-* filesystem based Kernel image, and Jailhouse still doesn't work, you should try booting this as your primary image, for testing purposes, as per https://e2e.ti.com/support/processors-group/processors/f/processors-forum/1176944/faq-linux-how-to-boot-sitara-am3x-am4x-am6x-devices-from-initramfs-cpio-archive-ram-disk Option 1:

1. Stop boot at U-Boot prompt
2. Load your new Image to ${loadaddr} using U-Boot commands
   

   # This loads from the 'boot' folder of the ext4-formatted rootfs on the SD card
   => load mmc 1:2 ${loadaddr} boot/Image-initramfs

   
   
3. Load your new DTB to ${fdtaddr} using U-Boot commands
   

   # This loads from the 'boot' folder of the ext4-formatted rootfs on the SD card
   => load mmc 1:2 ${fdtaddr} boot/custom.dtb

   
   
4. Boot your initramfs-based Kernel image...
   

   # Do the minimum bootargs setup for consistency sake with other flows shown here
   # (otherwise the dtb 'bootargs' property will take effect)
   => setenv args_initramfs 'setenv bootargs console=${console} ${optargs}'
   => run args_all args_initramfs
   
   # Now boot the Kernel without explicitly specifying the initramfs address
   # as it is fully baked into the Kernel
   => booti ${loadaddr} - ${fdtaddr}

   
   
   

Regards, Andreas

Hi Andreas,

I follow this steps

• Stop boot at U-Boot prompt
• Load your new Image to ${loadaddr} using U-Boot commands

# This loads from the 'boot' folder of the ext4-formatted rootfs on the SD card
=> load mmc 1:2 0xe0200000 boot/Image-initramfs

• Load your new DTB to ${fdtaddr} using U-Boot commands

# This loads from the 'boot' folder of the ext4-formatted rootfs on the SD card
=> load mmc 1:2 0xe0000000 /usr/share/jailhouse/inmate-k3-am625-sk-new.dtb

• Boot your initramfs-based Kernel image...

# Do the minimum bootargs setup for consistency sake with other flows shown here
# (otherwise the dtb 'bootargs' property will take effect)
=> setenv args_initramfs 'setenv bootargs console=${console} ${optargs}'
=> run args_all args_initramfs

# Now boot the Kernel without explicitly specifying the initramfs address
# as it is fully baked into the Kernel
=> booti 0xe0200000 - 0xe0000000

Thanks for running this experiment, I'd have expected this to work, but then I've never tried it myself. But looking at your error more closely it makes sense that it fails, as it tries to access a PCI host interface, which is NOT available when running natively on AM62x, only within the Jailhouse environment (running as an inmate). Your inmate DTS file should contain the below section, try removing that section (similarly like you before removed the "initrd*" related properties), and try again:

                pci@76000000 {
                        compatible = "pci-host-ecam-generic";
                        device_type = "pci";
                        bus-range = <0 0>;
                        #address-cells = <3>;
                        #size-cells = <2>;
                        #interrupt-cells = <1>;
                        interrupt-map-mask = <0 0 0 7>;
                        interrupt-map =

Looks like this is mostly working except the console. The Jailhouse inmate DTB tries to use MAIN_UART1, and the standard boot process (and early console) is configured for MAIN_UART0. So in order to better mimic how this Kernel+initramfs is used within the Jailhouse environment you should use something like the below sequence. Note how `bootargs` is explicitly configured to use MAIN_UART1 for both early console and main console.

=> load mmc 1:2 0xe0200000 boot/Image-initramfs
=> load mmc 1:2 0xe0000000 /usr/share/jailhouse/inmate-k3-am625-sk-new1.dtb
=> env set bootargs 'console=ttyS3,115200n8 earlycon=ns16550a,mmio32,0x02810000'
=> booti 0xe0200000 - 0xe0000000

It's important to configure for MAIN_UART1 as this is what is configured in the Jailhouse DTB file, otherwise you won't be able to get a console (the error you got). See extract from the AM62 Jailhouse inmate DTS file...

        aliases {
                serial1 = &main_uart1;
        };

        chosen {
                stdout-path = "serial1:115200n8";
        };

If you now get that image to boot from U-Boot directly, you should re-try getting it loaded into Jailhouse. Should you still have trouble loading it into Jailhouse, try re-building that image but instead of using an RT Kernel config, use a normal one, for testing purposes, to see if that has any impact.

Regards, Andreas

Hi Andreas,

I change dtb file

compiling time is coming error

how to fix error

Regards Veerapandiyan.

Don't change the inmate DTB file, it is already setup correctly for MAIN_UART1 operation. What I was asking is to change the bootargs in U-Boot to match.

Regards, Andreas

Hi Andreas

I have only u-boot not change dtb file but not on secondry os is showing some error i attached video link below: https://drive.google.com/file/d/11mIIXBpRQh4SYCjtPVJRmN3-1HWt3y0F/view?usp=drive_link u send one working video.

Thanks Regards,

Will need to prioritize other support work atm, and will pick this up again next week. Please ping me mid-next week or so in case I haven't gotten back on this yet.

Hi,

I'm still not able to get to it due to other priorities; it'll may take another week or so.

Hi Veerapandiyan, yes I'm back in the office but there is a very large backlog of other rather complex/urgent support work. I'm currently needing to prioritize other work items.

Hi Andreas

Its nice to see you back in office, i can understand the backlogs. We are in middle of signing an important project with the client we are finalizing the end details. It would be really great if you can answer our query within a day or two. We have to show our capability of porting the hypervisor. Everything is hanging on a loose thread. Please put our problem on priority. Hoping to see your reply asap
