Jailhouse in imx8qmmek board: cannot see logs on ttyLP2

lorenzo_sarchi · ‎11-18-2020

Good morning,

I have been trying Jailhouse on mek board.

As per dedicated jailhouse AN, the commands from the root are the following;

"

# insmod /lib/modules/4.14.98-imx_4.14.98_2.0.0_ga+g5d6cbeafb80c/extra/driver/jailhouse.ko

# insmod /lib/modules/4.14.98-imx_4.14.98_2.0.0_ga+g5d6cbeafb80c/extra/driver/uio_ivshmem.ko

# export PATH=$PATH:/usr/share/jailhouse/tools

# jailhouse enable /usr/share/jailhouse/cells/imx8qm-veth.cell

# /usr/sbin/jailhouse \

cell linux /usr/share/jailhouse/cells/imx8qm-linux-demo.cell \

/run/media/mmcblk1p1/Image \

-d /run/media/mmcblk1p1/fsl-imx8qm-mek-inmate.dtb \

-c "clk_ignore_unused console=ttyLP2,115200 \

earlycon=lpuart32,0x5a060000,115200 \

root=/dev/mmcblk0p2 rootwait rw"

But I cannot see nothing on ttyUSB1 on the Minicom of my PC, connected to the ttyLP2 rs232 on the baseboard

I understood that that used serial should be put on the ttyLP2 (I tried others too anyway).

The root is a Yocto compiled 4.14.98 Sumo.

The filesystem flashed in the eMMC is a 4.14.78, downloaded from the Web and flashed with the UUU Tool. Using the inmate dtb coompiled with Yocto root, I expect to see anyway some messages.

I see this log on the ttyUSB0, where I have the root OS, but this terminal is still i the "root"

(the jh_command.sh is just the long command mentioned above, that I repeat:

/usr/sbin/jailhouse \

cell linux /usr/share/jailhouse/cells/imx8qm-linux-demo.cell \

/run/media/mmcblk1p1/Image \

-d /run/media/mmcblk1p1/fsl-imx8qm-mek-inmate.dtb \

-c "clk_ignore_unused console=ttyLP2,115200 \

earlycon=lpuart32,0x5a060000,115200 \

root=/dev/mmcblk0p2 rootwait rw"

)

Hello Lorenzo,

As said on the github (https://source.codeaurora.org/external/imx/linux-imx/commit/?h=imx_4.14.78_1.0.0_ga&id=1afdd5020d49f...

Add a new init-on-array property, the clk driver will parse this array and prepare enable the related clocks. Previously, the clocks needs to be init on are hardcoded in SoC clk driver.

When we need to support two OSes, some clks needs to be ini on, however such clocks does not need to be init on for Single Linux OS environment.

At current stage using Jailhouse hypervisor supporting Two Linux OS, OS1 use SDHC2, OS2 use SDHC0, they share one IMX8MQ_CLK_NAND_USDHC_BUS_CG, because no power management supported, so we need clk_ignore_unused and make sure this clk being enabled, to make sure the 2nd OS could has SDHC0 working.

Regards

Good morning,

Any other suggestion?

Previous suggestion was not applicable. It was related to another board (imx8mq instead og imx8qm), and was related to 4.14.78 while I am already in 4.14.98.

Best Regards,

Lorenzo

Good morning !

Thanks for your explanation!

Looking into the patch, it seems than that this is for the imx8qm,

I have the i.MX8QM on mek board : imx8qmmek.

Looking the 2 files, clk-imx8qm.c and clk-imx8mq.c, in the clock driver (I use yocto Rel. 4.14.98) it seem they have some relevant differences.

Could you pls address me to the proper patch for the clk-imx8qm.c ?

Thanks in advance and best Regards,

Lorenzo

Good morning,

Just a further note:

The first set of errors seem to be indeed related to the serial clock.

[ 0.939263] msm_serial: driver initialized

[ 0.943473] fsl-lpuart 5a060000.serial: failed to get alias id, errno -19

[ 0.949954] imx8qm-pinctrl iomuxc: pin_config_set op failed for pin 23

[ 0.956105] fsl-lpuart 5a080000.serial: Error applying setting, reverse things back

[ 0.963509] clk: couldn't get clock 0 for /serial@5a080000

[ 0.980191] loop: module loaded

I use anyway the standard imx8qmmek inmate.dts included by default in the imx8qmmek board.

Best Regards

Lorenzo
