HIkey 960 recovery


#1

Hi,

I was facing some issues in Hikey960 target firmware, so i recovered the Hikey960 target as per the steps mentioned in https://www.96boards.org/documentation/consumer/hikey/hikey960/installation/board-recovery.md.html and flashed the kernel image and rootfs as in https://www.96boards.org/documentation/consumer/hikey/hikey960/installation/linux-fastboot.md.html

Following both the links to flash firmawre, bootloader and image, I did not see any error while flashing.

But I am not able to see any print on console. (both while flashing and after flashing the images)

I rebooted the target with autoboot mode(i.e. Switch 1 on, Switch 2 and 3 off) again but still no print on console.

Can anyone mention about any steps I missed or any other Link I should follow to recover the hikey960 target.

Thanks & Regards,
Akshay

Seems strange. Are you using 96Boards UART Serial Mezzanine to get the console? Also it is good to share flashing logs.

I do not see any error in the flashing of images.

Thanks you for your help

You won’t see console on HDMI as current Debian kernel doesn’t have corresponding driver support.

Most probably it seems to be an issue with your UART Mezzanine. Can you try to test it with any other working board?

Hi guys,

Just remind, due to Hikey620 latest snapshot booting binaries are broken now, so I am concern if Hikey960 has the same issue. I remembered the older one building binary should be safe: http://snapshots.linaro.org/96boards/reference-platform/components/uefi-staging/76/hikey960/release/ .

Hi leo,

Thanks for the reply.

I doubt because i am able to recover other hikey-960 targets with these images.

I am facing issue in one particular target.

Also, I am able to see the led blink on keyboard press(input), but nothing is coming on console.

I need to confirm if its an hardware issue and will I be able to fix it.

Thank you for your reply i will check with the older the images from the link you mentioned.

Regard,
Akshay
