Cannot boot into WinPe for Windows 10 IoT

hankwang — Mon, 21 Aug 2023 06:31:38 GMT

Hi,

I have a 8MP CPU with 4GB DDR. When the system is ready to enter WinPE, the system will crash.

I use windbg to observe the problem. I see "Missing Image Name". I guess the problem is related to

DDR size?

Since i have an sd card with a windows 10 IoT image, I flashed the EVK bootloader in the sd card.

I can boot into WinPE normally. I only modify the DDR parameter in the same sdcard. The sd card is put

in my system, but the system will crash on boot wiepe screen.

Do you have any ideas?

Hi @hankwang,

BSP from version 1.4.0 uses whole 6GB RAM of i.MX8MP EVK for Windows 10 IoT:
• 3/2023: W1.4.0
– Supported boards:
...
– 8MPLUSLPD4-EVK Evaluation Kit
...
– New features:
– General
– 8MPLUSLPD4-EVK: The size of SDRAM was increased to 6 GB. Note: This change requires
windows10.0-kb5019275-arm64_c6c2abc31137d43e762304bd1542ba413d2b8b9e.msu to be
installed. The patch is applied in installation script (make-winpe-enterprise.cmd) by default.

Uboot still uses only first 3GB of RAM.
Limiting RAM size to 3GB before version 1.4.0 was done by setting PcdBank1MemorySize to 0x0.
You can either try to limit it to 3GB as it was before by setting this:
/mu_platform_nxp/NXP/MX8M_PLUS_EVK/MX8M_PLUS_EVK.dsc:
giMX8TokenSpaceGuid.PcdBank1MemorySize|0x000000000000000
(alternatively you can try to use firmware from W1.3.0, but it is without warranty, when use together with Windows drivers from different version)
or you can try to set it to 1GB to allow Windows to used all 4GB, not only 3GB

giMX8TokenSpaceGuid.PcdBank1MemorySize|0x0000000040000000

You can find firmware for 8MPLUSLPD4-EVK Evaluation Kit for 4GB RAM and patch file for firmware of BSP 1.4.1. Firmware is signed with test key.

Best Regards, Jakub

Hi ,

Thank you for your reply. I add your patch in UEFI code. When the system is ready to enter WinPE, the system displays a blue screen.

Do you have any idea?

Also, I tried to use version W1.3.0. The system can enter WinPE and complete Windows 10 IoT Image flash to eMMC.

Hi @hankwang,

can you please try to set the size of Bank1 to 0 as it was in W1.3.0?

giMX8TokenSpaceGuid.PcdBank1MemorySize|0x0000000000000000

Note:

While using signed firmware, you need to have written "RPMB write key" in eMMC, otherwise boot will fail. So if you do not need to use TPM, please use unsigned firmware.

Best Regards, Jakub

hankwang — Wed, 23 Aug 2023 14:26:47 GMT

hi, yes. I have set giMX8TokenSpaceGuid.PcdBank1MemorySize to 0. And I'm not using signed firmware, I'm only using unsigned firmware. I checked this BSOD cause is memory issue.

Is there anything else for memory setting that needs to be modified?

Hi @hankwang,

what board are you please using for these test, EVK or custom board?

Do you have in your project correct DDR timing file for your board? For example lpddr4_timing.c. But if firmware from 1.3.0 is working, this should not be an issue, both 1.3.0 and 1.4.1 use the same timing files for EVK.

I have tested this patch on i.MX8MP EVK board with 4GB DDR chip and was able to install with Win PE and enter Windows without an issue.

Best Regards, Jakub

hankwang — Mon, 28 Aug 2023 02:27:13 GMT

As far as I know, the 8MP EVK board only has 6GB DDR. Do you use 6G DDR to simulate 4G DDR?

I have a custom 8MP CPU with 4G DDR. Maybe you can find a real 4G DDR to test.

Re: Cannot boot into WinPe for Windows 10 IoT

jakub_zigacek — Mon, 28 Aug 2023 07:09:24 GMT

Hi @hankwang,

I have borrowed EVK with DDR slot. We have one for testing various DDR chips. I have in it this 32Gb one https://tw.micron.com/products/dram/lpdram/part-catalog/mt53e1g32d2fw-046-aut.

I have also information, that the firmware_uuu_8MP-EVK-4GB.bin works with BSP 1.4.1 on another custom board with only 4GB DDR.

I will try to ask at our R&D if they are aware of some other differences between 1.3.0 and 1.4.1.

Best Regards, Jakub

@hankwang

Can you make sure you are also applying windows10.0-kb5019275-arm64_c6c2abc31137d43e762304bd1542ba413d2b8b9e.msu to the WinPE image as well?

This is our guide for how to update the WinPE image. You will need to install all of the NXP drivers to the WinPE image, as well as update it with the .msu referenced above. https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/winpe-mount-and-customize?view=windows-10

Hi , Yes, I installed this patch in Win10 Image. You can refer to the attachment.

Hi @hankwang,

I discussed this issue with our DDR expert. He would like to check datasheet of your DDR chip, because of variety of possible DDR internal organization. Can you please provide this datasheet?

Best Regards, Jakub

Re: Cannot boot into WinPe for Windows 10 IoT

hankwang — Tue, 29 Aug 2023 08:41:20 GMT

hi, This is our DDR name. But I still search the datasheet. Perhaps you can download directly from the Micron website.

https://tw.micron.com/products/dram/lpdram/part-catalog/mt53e1g32d2fw-046-wt?login

DDR Name: MT53E1G32D2FW-046 WT

Also, I can start Windows10 IoT for W1.3.0.

Re: Cannot boot into WinPe for Windows 10 IoT

jakub_zigacek — Tue, 29 Aug 2023 09:18:01 GMT

Hi @hankwang,

Do you have MT53E1G32D2FW-046 WT:A or MT53E1G32D2FW-046 WT:B?

Because A has one chip select and B has two chip selects.

You are using firmware from W1.3.0 as it is in downloaded zip from NXP pages?

Best Regards, Jakub

Re: Cannot boot into WinPe for Windows 10 IoT

hankwang — Tue, 29 Aug 2023 10:01:01 GMT

Sorry that DDR is MT53E1G32D2FW-046 WT:A (one chip).

Yes, W1.3.0 download from NXP website. I just modified backlight control pin in the mu_platform_nxp folder.
and DDR parameters(lpddr4_timing.c & imx8mp_evk.h) in the u-boot-imx folder.

And I set LVDS0 to display in galcore.inf.

; HKR,,Display0Interface,%REG_DWORD%,%DISP_INTERFACE_HDMI%
HKR,,Display0Interface,%REG_DWORD%,%DISP_INTERFACE_LVDS0%

jakub_zigacek — Tue, 29 Aug 2023 13:58:45 GMT

Hi @hankwang,

here is a timing file for your DDR chip. But it is prepared for our EVK and thus the mapping of data bits could be different then on your board. You need to change this structure, if you have different mapping

/* PHY Initialize Configuration */ struct dram_cfg_param ddr_ddrphy_cfg[] = { ...

But if your timing file is tested for example with linux and DDR works well, we have to look elsewhere.

@hankwang @jakub_zigacek

Thanks. I looked at NXP's build script, and it appears the script automatically installs all patches in the /kbpatch/ folder for the Windows IoT Enterprise image, but does not do the same for the WinPE image. To fix this, please add the following lines to the make-winpe-enterprise.cmd script in Step 2.6, immediately after line 565:

if %NO_PATCH% == no (

set KB_COUNT=0

for /f "tokens=*" %%i in ('dir /b %KB_PATCH_DIR%\*.msu') do (

set /a KB_COUNT+=1

echo Applying cumulative update %%i from %KB_PATCH_DIR%...

call :clrEcho 02 "WARNING Depending on size of the update, this processs may take up to 30 minutes, do not stop the process even if it may appear to be frozen"

echo:

echo dism /Image:"%WIN_PE_MOUNT_DIR%" /Add-Package /PackagePath="%KB_PATCH_DIR%\%%i"

dism /Image:"%WIN_PE_MOUNT_DIR%" /Add-Package /PackagePath="%KB_PATCH_DIR%\%%i" || goto ErrExit

)

I've also attached the script that I've modified with the above to this thread. To use it, extract the archive, rename it to make-winpe-enterprise.cmd and replace your existing script with this one.

Try this out and let me know if that fixes the issue for you.

Hi I used the new build tool you provided but I still have bsod issue.

In addition, we can know where to download the dolphin test tool for ARM. Just like an attachment file

Re: Cannot boot into WinPe for Windows 10 IoT

hankwang — Fri, 01 Sep 2023 03:36:36 GMT

Hi , I am using the new DDR parameters. But the bootloader will stop while ddr is training.

Also, may I know what size is required for eMMC for W1.4.1 Windows 10 IoT install?

Because my eMMC is 8G. After I installed W1.3.1 Windows 10 IoT, the remianing eMMC is 584MB.

Is my eMMC too small to install W1.4.1 Windows 10 IoT?

Re: Cannot boot into WinPe for Windows 10 IoT

jakub_zigacek — Fri, 01 Sep 2023 07:36:51 GMT

Hi @hankwang,

can you please sent us boot log from console , your timing file, schematic ( DDR section ) a DDR datasheet?

I would like to get back to what works on your board. You have written:

Yes, W1.3.0 download from NXP website. I just modified backlight control pin in the mu_platform_nxp folder.
and DDR parameters(lpddr4_timing.c & imx8mp_evk.h) in the u-boot-imx folder. + inf file changes.

I expect, that now you have in eMMC installed W1.3.0. Can you please try to do the same changes you have did to 1.3.0 to 1.4.1 firmware? Plus set zero to bank1 size, like it is in 1.3.0.

giMX8TokenSpaceGuid.PcdBank1MemorySize|0x000000000000000

And try to boot the board with this firmware?

Second thing what can be tried is to use firmware of 1.3.0 together with 1.4.1 windows installation on SD card, to see if the installation will finished correctly.

About the eMMC size if 8GB is enough, I would say that without optimization of install image it is not enough. Microsoft offers some help to reduce its size here https://learn.microsoft.com/en-us/windows-hardware/manufacture/desktop/compact-os?view=windows-10#size-requirements-and-considerations. There is stated that 8GB is not enough for usage even if you are able to install it.
