Windows10 IoT on iMX8M-Quad

[aniketwaje]

Hello Team,

I'm porting windows 10 IoT Enterprise to my custom board (imx8mq). I am using BSP version 1.2.1.

I followed Quick start guide and able to create a WinPE SD card. Now I wanted to flash firmware on SD card.

Where firmware.bin has to be flashed? While creating WinPE SD card my SD card has been partitioned in 2 drives H: and F: for H: it labled WinPE. and for F: it shows empty. 

I continued by flashing firmware in F: and tried booting from SD card boot mode. My HDMI display shows windows logo and starts installing windows IoT into eMMC. After successful installation it prompts rebooting. After rebooting it takes me to BIOS (BIOS image attached for reference) and even after hitting continue nothing happens.

Then I manually rebooted board in eMMC boot mode. I get stuck in Starting Kernel (logs attached for reference) and also there is no display over HDMI.

This same happens even if I flash firmware in H: drive

My custom board supports HDMI and MIPI-DSI. I am not using any converter for the display.

Hi @aniketwaje ,

your description looks like there's no bootable device recognized by the UEFI. The guide describes how to add WinPe to the SD card. You could tell if it has been done correctly by examining the card. It will contain a lot of files and an "EFI" directory. If you have jumper-ed the board to load boot firmware from SD card remember to re-flash it as the card gets reformatted everytime you put WinPe there.

Good luck

Hi @aniketwaje ,

In the BIOS screen are other inputs registered correctly? (for example, are you able to switch between other options? or are you able to select any other options besides ''Continue''?)

Is the size of your SD card at least 8 GB? 

Have you tried using other SD cards to discard that the issue comes from a faulty SD card?

The Quick Start Guide section regarding flashing the image to the SD card recommends the board to be in SD Card Boot Mode in order to successfully boot into Windows 10 IoT Enterprise. 

Have you tried booting into the WinPE installer again? This is done by renaming the folder ''_efi'' at the root of your SD card to ''EFI''.

Let me know if this was of any help.

Best regards,
Hector.

Hello @hector_delgado 

Thank you for quick reply.

In BIOS screen I am able to select boot next value and also able to save it. but after reboot the value values get reset, but I am unable to change boot order, boot option apart from that I am able to change languages, Boot Manager etc. but same it gets reset after reboot.

Size of my SD card is 16GB (HC) Class 10 with speed of 10 MB/s.

Yes I am using 2 same SD cards. If one is faulty other should work, but its same for both SD cards.

In SD card boot mode I end up with BIOS screen and if I switch boot mode to eMMC with SD card inserted I end up with "Starting Kernel" log and No display over HDMI.

Yes I re-tried booted into WinPE by renaming _efi to EFI still results are same.

Thank you.

Hi @aniketwaje ,

Have you verified that previous versions of Windows 10 IoT Enterprise work without any issues? I would suggest trying previous releases to ensure that there's no compatibility issues with your board.

I would also suggest that if the prebuilt images used in the Quick Start Guide don't work then try building an image as instructed in the User Guide (https://www.nxp.com/docs/en/user-guide/IMXWGU.pdf).

Let me know if any of these fixes your issue.

Best regards,
Hector.

Hello @hector_delgado ,

I tried previous versions 1.2.0 binaries as well as source it ended up same in BIOS. The noticeable thing is in BIOS I was unable to set any configs.

 However, I also tried versions previous then 1.2.0 binaries, in that I was unable to created SD card as it gave mem error in Injecting Galcore (Graphic) driver in SD card.

Are there any working logs for Windows IoT for imx8mq SoM available? If yes can you please share ? 

Thank you !

Hi @aniketwaje ,

Unfortunately, we don't provide support for Windows 10 IoT Enterprise on custom boards. We only provide support for Windows 10 IoT Enterprise on our EVKs. I ran common troubleshooting with you before in hopes your issue would be hastily solved. I apologize for any inconvenience caused by this.

I hope your problem is solved soon.

Best regards,
