# Contributing to Linaro release Kernel for HiKey boards

This page provides instructions for developers willing to contribute to the
Linaro release kernel for HiKey boards.

# How to contribute

The following mailing list has been created to contributions:

[HiKey-Kernel mailing list]

This is a public mailing open to any developer.

# General recommendations

* This mailing list is not a substitute for proper upstreaming. We are willing to accept patches against our release (e.g. generally that means against a stable/LTS branch), if the submitters are also willing to upstream their changes. We will not be maintaining orphaned patches forever.

Great! what about hikey960 compatibility?

Mani · December 21, 2018, 1:38pm

@Loic 4.19.5 kernel based Debian snapshot image release for HiKey960

Same debian image is used for HiKey, HiKey960 and HiKey970. It is the UEFI build passing corresponding DTB for differentiating the boards.

Hi @Mani

quick question for you: I have a 2Gb HiKey 620 from LeMaker (attached via a serial console
extension card to my USB serial port) and I’m trying to run your latest bits on it. I’ve downloaded
the .sd.gz file, ungzip’ed it and wrote it to my 8Gb SD card. I can now boot from that card and I
see the GRUB menu. Once I pick any options in the grub menu I see:
Loading Linux 4.19.5-hikey …
Loading initial ramdisk …
EFI stub: Booting Linux Kernel…
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map…
and then nothing. The kernel doesn’t print anything onto the console
and the board just sits there doing nothing.

Any advice for me on how to proceed with these latest bits?

Thanks,
Roman.

P.S. I have a very old Debian successfully booting on it so I can give you
any kind of /proc or /sysfs output that may help with debugging.

Hi @rvs,

Have you tried flashing latest UEFI binaries from below link?

Thanks,
Mani

rvs · December 30, 2018, 7:48am

One more question @Mani – could you please share a config that was used to build the kernel?

Thanks,
Roman.

Mani · December 30, 2018, 8:13am

@rvs You can follow this guide for building linux kernel: https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/build/linux-kernel.md

We use, make defconfig distro.config for building and updating the kernel as a debian package, However, if you are updating the kernel by any other means (abootimg) you need to select UFS as built-in (by default it is =m in defconfig)

rvs · January 3, 2019, 8:45pm

Hi @Mani!

when you say UFS, what module specifically do you mean?

Thanks,
Roman.

Mani · January 6, 2019, 3:01pm

@rvs

CONFIG_SCSI_UFSHCD=y
CONFIG_SCSI_UFSHCD_PLATFORM=y
CONFIG_SCSI_UFS_HISI=y

Hi Mani,

After looking at the device tree files, I noticed that PCIe definition support is missing (which I was already guessing was the reason why eth was not supported).
Are you (or anyone else) working actively on that support?
If yes, any idea when it can be pushed to your git repo?

Kind regards

SAlves

Mani · January 7, 2019, 2:13pm

Hi @salves,

PCI-E is already supported on HiKey960. But I didn’t mention in the release notes because I don’t have a device to test it (should have added a note, will do the it). But HiKey970 PCI-E support will come after UFS, and SD. There is no one actively working on it but I will work on it whenever I have free time

Thanks,
Mani

davidt · January 13, 2019, 11:30pm

@Mani thanks for the great work! Unfortunately, this build did not work on original 1g/4g HiKey, due to some eMMC initialization error as documented here: https://github.com/ARM-software/arm-trusted-firmware/pull/1724

My question is, could you please initiate a new build process now that the fix has been identified and merged? I see the fix is fairly minor, and could proably try to compile here, but I’d really like to simply download a proper Linaro build that has gone through the official build system.

I think it should end up landing in here, if I am not mistaken: http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/latest/hikey/debug/

Thanks!

Mani · January 22, 2019, 5:34am

Hi @davidt,

Thanks for letting us know about this issue.

Sure, we will spin a new UEFI build so that you can flash the TF images with the fix incorporated.

Thanks once again!

Hi Mani, is there any update for hikey970 PCI-E support?

Mani · March 14, 2019, 2:06pm

Hi @brfeng,

I’m still working on it. Please stay tuned for the updates.

Thanks,
Mani

brfeng · March 15, 2019, 3:34am

Hi @Mani,
Could you please share your process of this work? I have an urgent task that need to run latest kernel on hikey970 board.

Thanks a lot,
Reid

Mani · March 19, 2019, 7:24am

Hi @brfeng,

For using PCI-E on Hikey970, you need to do a couple of things:

Update the bootloader to enable LDO33 (required for PCI-E switch on the board). For this, you need to use my fork below:

You can use the below guide to build and flash the firmware onto Hikey970 board.

# HiKey970 Board Recovery

This page outlines steps needed to recover your HiKey970 board from a bricked software state. This instruction set is suggested to those who are experiences boot issues due to a corrution in the file system and/or other software components.

## Installing a Bootloader

For most users a board can be “recovered” from a software failure by reloading the operating system. However, if the primary bootloader in the UFS flash memory has been corrupted then the bootloader will need to be re-installed. This section describes how to reinstall the primary bootloader.

#### Build Recovery Binaries

Following instructions are used to build the recovery binaries for Hikey970.

##### Install dependencies

Following dependencies needs to be installed for building the bootloader binaries

(to be specific, just use my OpenPlatformPkg fork instead of the one mentioned in the instructions)

Build and flash the below kernel onto Hikey970 board:

https://git.linaro.org/people/manivannan.sadhasivam/96b-common.git/log/?h=hikey970_pcie

Just use ARM64 defconfig. You might also want to make UFS driver as built-in.

Thanks,
Mani

brfeng · April 25, 2019, 11:01am

@Mani ,
Thanks for your help. I can boot the latest kernel on hikey970 now. But HDMI and usb drivers cannot work. Could you give me some suggestions for how to support HDMI and user drivers?

Mani · April 25, 2019, 12:20pm

Hi @brfeng,

I haven’t added HDMI and USB support yet. These are on my TODO list but can’t give any fixed estimate. Will make a noise in the forum if I happen to add support for these.

twonox · June 24, 2019, 6:02am

Dear Mani,

same days recently i found
rootfs-linaro-stretch-developer-hikey-20190520-31.img.gz
over your link here to the last hikey snapshot image.
In same folder i found a rootfs-31.img alip version download link.
But dosen’t available back in the day.

Still possible come up to version 31 alip, developer, rootfs, boot and sd files ?

I must weep bitterly
