Could you confirm which ufs model you are using? AFAIK, the hynix UFS chip has one potential timing issue so there have patch to fix it [1], so it’s good to check if the ufs failure is impacted by this issue.

Atleast I was able to boot and go to login. Thanks for your help. When I connect my hdmi and run "startx’ I dont see anything in display.

Hi,

Currently there is no support for HDMI and there is no support for HDMI driver now afaik. So, the x-server won’t be able to setup a display and start. In your output you can see it is failing to open any driver.

[leo-yan]

Hi,

Please check if below two discussions are helpful for HDMI enabling, though the discussion are based on Debian Rootfs, but it also uses /dev/fbdev for displaying:

How can we deploy latest image with UEFI on hikey960?

Thanks to everybody’s help, I was able to get it working with both console version and desktop version. I needed to run some browser benchmarks and thus really needed desktop version. Here are some recap of the whole process so that others can duplicate exactly. Download UEFI build from latest snapshot 100 (not UEFI stagging build which is 1 month older), http://snapshots.linaro.org/reference-platform/embedded/morty/hikey960/100/rpb/bootloader/ Follow previous instruction to install UEFI…

Does latest rpb desktop image (Debian) supports hdmi on hikey960?

@ric96 Looking at kernel version, it seems you are running Debian on which HDMI/DRM drivers doesn’t seems to work. So I had to install custom 96boards hikey kernel (https://github.com/96boards-hikey/linux/commits/hikey960-upstream-rebase) on Debian and passed “video=HDMI-A-1:1280x800@60” in cmdline for my 24 inch monitor screen. Kernel install steps: “Image.gz” should be used to replace /boot/vmlinuz-4.15-hikey image. And for device tree, you will get hi3660-hikey960.dtb image. Place this ima…

Hi
I built latest morty updating ufs.patch. still not able to boot. if i remove device tree from grub commandline, i am able to login but video will not work because /dev/fb0 is not created. below is the boot log i see when i try to boot with devicetree

Hi,

@Ravi

I built latest morty updating ufs.patch. still not able to boot. if i remove device tree from grub commandline, i am able to login but video will not work because /dev/fb0 is not created. below is the boot log i see when i try to boot with devicetree

Could you confirm you can boot system with debian building images [1]? Maybe it’s good firstly to confirm if the board is healthy or not by using prebuilt images.

It might be the system is stuck and you could see the last four lines seems the output log from firmware but not the kernel. Could you confirm you are using Hisilicon legacy booting images or UEFI/ARM-TF open sourced boot images? I suggest you could use the latest UEFI/ARM-TF images [2].

The root FS has not been mounted successfully. Have you flashed rootFS to ‘system’ partition with below command:

sudo fastboot flash system xxx.img

Hi Leo-yan,

Thanks for the reply

I confirmed, Debian image works fine. I wanted RPB because i need to remove some modules and evaluate this board for our qt application.

I am using the bootloader binaries built in master branch as bootloader binaries from Morty is not working while flasing prm_ptable.img. befory applying the ufs patch it used to get stuck as posted in original post. but after applying patch i can see kernel logs appearing if i remove “quiet” from kernel command line. also when i remove devicetree command from grub, i can login successfully only problem is /dev/fb0 will not get created so i can’t run my qt GUI applications.

yes I flashed the system partition correctly. i can see this log even in debian image but it boots properly.

I have built and tested on master branch and i can see same problem here also.

incidentally i set my dip pins to fastmode and forgot that it is continuously rebooting by chance sometimes device is coming up successfully and i can login successfully. may in one time in 20 to 30 reboots its coming up. i am continuing like this for now …

i can login successfully only problem is /dev/fb0 will not get created so i can’t run my qt GUI applications.

Try to pass something like “video=HDMI-A-1:1280x800@60” (I use it for my 24 inch monitor) via cmdline.

[Ravi]

this is always part of my kernel commandline.
/dev/fb0 will not get created even when i pass this option without grub command
