4.19.5 kernel based Debian snapshot image release for HiKey960

Hi @Mani, since I’m looking at the latest debian should be “30” from Linaro Snapshots is the kernel 4.19.5 in this release or in previous one? also sd card image has that kernel? Thanks

Yes, release 30 is based on 4.19.5 kernel but there is no SD card image.

sorry @mani but i see http://snapshots.linaro.org/96boards/hikey/linaro/debian/30/linaro-stretch-developer-hikey-20190420-30.sd.gz , am I in the right repo?

@francesco_camarda I should’ve clarified. We do have SD card image but it is not tested on Hikey960!

@mani …I tested it and was not working, the latest working kernel for debian sd for me is the 4.18.
So i will try the UFS debain image, Thanks! F.

@mani, the UFS image is fine, the SD card one is freezing @:

where the kernel seems to init the mmc card another time.

@Mani
Hi Mani, are you going to test the SD card image too? Is there any instruction or suggestion that you could provide to make the SD image boot?

Thanks,
Marco

@Mani I am also unable to boot 4.19.5 via SD card on hikey960. UEFI hangs in console when any SD card is present at boot.

@francesco_camarda @marcodip SD boot issue is now fixed: manivannan.sadhasivam/linux.git - Linux kernel tree for personal upstream work

Next debian image build (#34) should boot from SD without any issues.

Sorry for the long delay.

Thanks,
Mani

Hi,

To build we should:
export PATH=~/gcc-linaro-7.4.1-2019.02-x86_64_aarch64-linux-gnu/bin/:$PATH
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- defconfig distro.config
make ARCH=arm64 CROSS_COMPILE=aarch64-linux-gnu- -j24

BUT and how to flash this new kernel to the board ?
/boot in the board doesn’t have a DTB , so I assume I have to glue together with the kernel image, but how to do that ?

How to generate this files :
root@linaro-developer:~# ls -l /boot/
total 17568
-rw-r–r-- 1 root root 4770026 Dec 17 2018 System.map-4.19.5-hikey

-rw-r–r-- 1 root root 8728842 Dec 17 2018 vmlinuz-4.19.5-hikey

Thanks

Couple of options:

  1. Build the kernel and modules as a debian package and install it on the board. More info here: https://github.com/96boards/documentation/blob/master/consumer/hikey/hikey620/build/linux-kernel.md#build-the-linux-kernel

This is the preferred option. Only thing to make sure here is to copy the dtb to the board and modify the boot parameters at grub.

  1. Copy the dtb and vmlinuz* to SD card’s boot partition and copy the modules to rootfs partition. Then modify the grub parameters to pass the correct dtb as mentioned in the guide I shared above.

Thanks,
Mani

Is there a patch to enable support for I2S0 , the I2S at the low speed connector ?

Hi, I tried to update Kernel to 5.1-rc6 using option 1 but I have this issue at start:

Loading Linux 5.1.0-rc6 …
Loading initial ramdisk …
EFI stub: Booting Linux Kernel…
EFI stub: EFI_RNG_PROTOCOL unavailable, no randomness supplied
EFI stub: Using DTB from configuration table
EFI stub: Exiting boot services and installing virtual address map…

Platform exception reporting:
ESR_EL3: 0000000092000210
ELR_EL3: ffffff8010770fe4

Never seen an issue like this. Did you update UEFI and base firmware to the latest ones available?

Hi Mani,

I am using uefi_76, is a newer version available?

I simply run this command:
# ./hikey_idt -c config.orig -p /dev/ttyUSB1

# cat config.orig
hisi-sec_usb_xloader.img 0x00020000
hisi-sec_uce_boot.img 0x6A908000
recovery.bin 0x1AC00000

Hi @Mani, do you have any news?

Thanks,
Marco

Can you give me any suggestion?

darn… I pushed the fix to the wrong tree and hence the new build didn’t boot. I’ve triggered build #35 now after updating the correct tree. Please test and let us know when the images are available.

Sorry for the inconvenience.

-Mani

@marcodip Build #35 is available now: Linaro Snapshots

Please test and let us know.

Thanks,
Mani
