Yocto Harpoon for iMX8MN custom board

[khang_letruong]

Hi Forum,

I am porting Yocto Harpoon for an iMX8MN custom board. So far, I could generate and load the imx-image-core into the board then stopped at u-boot prompt and ran :

setenv jh_root_dtb imx8mn-custom-harpoon.dtb
run jh_mmcboot

However, the system seemed to run very slowly and I could not reach the Linux console any more:

Hi,

Thank you for your interest in NXP Semiconductor products,

The mentioned DTS is required to boot, please fix that.

But the issue is likely to porting issues, please go through the following posts and review your built image, try both solutions.

Hi @JosephAtNXP,

Thanks for your support. Our custom board is similar to the iMX8MN EVK in terms of DDR memory (2 GiB) with only difference being the Ethernet PHY. So it would be straightforward for the porting. Of course we did the DDR training and the board works well with Yocto without Harpoon.

I think my current problem is that the jailhouse mode could NOT be entered even I added the imx8mn-custom-inmate.dts copied from imx8mn-evk-inmate.dts with slight change in the header :

        model = "NXP i.MX8MNano CUSTOM board";
        compatible = "fsl,imx8mn-custom", "fsl,imx8mm";
        interrupt-parent = <&gic>;
        #address-cells = <2>;
        #size-cells = <2>;

Hi again,

Also, currently I only have access to the main console. Am I missing any UART connection for interacting with Jailhouse?

Thanks,

K.

[khang_letruong]

Hello @JosephAtNXP,

Could you help to give more instruction about interracting with the Jailhouse on iMX8MN based board, please?

[JosephAtNXP]

Hi,

The EVK boards expose serial ports through their USB debug interface. One of these serial ports is used by Linux for its console, and another one is used by the guest RTOS.

To run the reference applications, open both serial ports with terminal emulators. Insert the micro-SD card, on which the Yocto image has been flashed, in the EVK and power up the board.

Make sure that your boot partition has the DTB and that your environment points to it.

u-boot => setenv jh_root_dtb imx8mn-evk-harpoon.dtb
u-boot => run jh_mmcboot

Regards,

[khang_letruong]

Hi @JosephAtNXP,

I double-checked the console output of NXP's iMX8MP-EVK flashed/installed with the Yocto Harpoon of the same BSP version and got similar trace for the main debug console :

I expected that there would be certain log relevant to the launching of the jailhouse mode but there was not.

Full log is in attachment.

Could you help?

K.

I just found the reason in another discussion : https://community.nxp.com/t5/i-MX-Processors/iMX8MP-EVK-Unable-to-launch-jailhouse-mode-with-Yocto-H...

[khang_letruong]

Hi again,

Compared to other device-trees of the EVKs and linked to my previous ticket, is the missing of imx8mn-custom-inmate.dts the cause ?

The following guide also seems to add the inmate related device-tree as well : https://variwiki.com/index.php?title=Jailhouse_Guide&release=mx8mn-yocto-mickledore-6.1.36_2.1.0-v1....
