Failed to launch xen on J6 evm

Failed to launch xen on J6 evm

[Korupol, Naveen (EXT)]

[-- Attachment #1.1: Type: text/plain, Size: 2629 bytes --]

Hi

I am using J6 evm.

Tried to launch xen and it fails after reporting starting kernel.
I tried to change the load addresses and
played with couple different u-boots and file system images...but still on square 1.

I would like to know if this is a known issue with J6 EVM and
If there are any probable fixes/hints for bringing up XEN on J6 evm.

Here is the boot log where it hangs...

Does your u-boot launch the kernel (AKA Xen in this case) in NS.HYP
mode?

Given where things are apparently hanging I think the first step would
be to enable early printk for your platform.

See docs/misc/arm/early-printk.txt and the long ifeq chain in
xen/arch/arm/Rules.mk.

If the UART on your platform is one of the existing ones in
xen/arch/arm/arm*/debug*.inc then this is pretty easy.

If not then you just need to provide two ASM macros early_uart_ready and
early_uart_transmit which is pretty trivial for every UART I've ever
seen -- see the existing debug*.inc for examples.

Hi Ian

I am (awesome) glad to see your response.


[IC] J6 EVM?
[NK] is a TI (& Spectrum Digital) evaluation board built on OMAP 5 architecture which has 2 ARM Cortex-A15 core(s), 2 Cortex-M4 cores and SGX544 3D graphics core(s).

[IC] enable early_printk
[NK] now I have enabled early_printk, I see that processor is not in hyp mode as you correctly envisioned.

Starting kernel ...

- UART enabled -
- CPU 00000000 booting -
- Xen must be entered in NS Hyp mode -
- Boot failed -

I took my current U-Boot from:
>>>> Xen needs to be started in non-secure HYP mode. Use this U-Boot Git repository:
>>>> git clone git://github.com/jwrdegoede/u-boot-sunxi.git
And compiled it for dra7xx_evm_config.

Is there any specific U-Boot for ARM with this HYP mode already enabled correctly?
If not, I would appreciate any links to help me update my current u-boot to have this setting enabled.

Thanks
Naveen Korupol

It's generally pretty platform specific, rather than architecture
specific how to do this unfortunately.

I think you had identified a very similar board, so you might have some
luck with looking at the u-boot used on that.

In mainline u-boot support for hyp mode started appearing throughout
2014. So probably the first step would be to try and get a more recent
(e.g. mainline) u-boot onto your board.

You should ask the people who make the board for support with this
and/or look around for a community around the platform you are using.

You can get uboot from the U-Boot website is at
http://www.denx.de/wiki/U-Boot
which might have HYP enabled for your board, but you are probably 
going to have to edit the uboot code to enable it, for example by 
comparing the settings for a board that does have HYP enabled.

This suggests that your DTB does not describe the maintenance interrupt
on the interrupt controller node.

Re: Failed to launch xen on J6 evm

[Korupol, Naveen (EXT)]

Hi Ian/Team

It finally looks like xen and dom0 are stable, but the cli seems tricky.

I can switch between xen/dom0 but cannot execute xm cmds...

Any idea where I went wrong? Please find the log below - thanks

xm was dropped in xen 4.5. Use xl instead.

As Michael says, xm doesn't exist any more (and never existed on ARM),
use xl. But, are you even getting a dom0 cli prompt? It doesn't look

Is there no dom0 output from this point on?

Have you enabled CONFIG_XEN in your dom0 kernel config, along with all
the other Xen option, in particular CONFIG_HVC_XEN?

You will also want to arrange for a getty process to run on hvc0 so you
can login.

Hi Ian

CONFIG_XEN iand CONFIG_HVC_XEN are enabled =y in .config
other config settings seem to be in line.

getty was not properly setup in my dom0 settings - thanks

Re: Failed to launch xen on J6 evm

[Korupol, Naveen (EXT)]

Hi Ian

I cannot see dom0 login prompt.
I presume its unable to find the rootfs itself where the getty settings are present and I tried to include initramfs but that gave me a different elf related error.

Is there any dom0 kernel and rootfs pair that I can use to test this setup for armhf rather than building locally?
Kindly let me know if the boot params are still correct: - thanks

xen-bootargs           dom0_mem=512M console=dtuart dtuart=serial0 dom0_max_vcpus=2 bootscrub=0 flask_enforcing=1 noreboot early_printk
dom0-bootargs       console=hvc0 psci=enable clk_ignore_unused root=/dev/mmcblk0p2 rw rootwait init=/sbin/init nomodeset earlyprintk=xen debug maxcpus=8 loglevel=10

my boot hangs as per log below: ( ctrl+aaa still moves between xen  and dom0 consoles, I can query * in xen console that shows all that system info...any clues from there??)
