frdm-imx93 not booting even with demo images from NXP

I am trying to bring up the frdm-imx93 from the SD Card. It works just fine from the emmc.

I downlowaded ZIPRev 4.0Jun 25, 20252.45 MBLF_v6.6.36-2.1.0_images_FRDM_4.0_IMX93 from the NXP site link. THen I did the following:

zstd -d imx-image-full-imx93frdm.rootfs.wic.zst

sudo dd if=imx-image-full-imx93frdm.rootfs.wic of=/dev/sdc bs=1M status=progress && sync

sudo dd if=imx-boot-imx93frdm-sd.bin-flash_singleboot of=/dev/sdc bs=1k seek=32 status=progress

Then I put the sdcard in the slot and tried to boot, after setting SW1[3:0]=0011.

However the boot does not progress beyond this point:

U-Boot SPL 2024.04+gde16f4f1722+p0 (Sep 02 2024 - 10:44:35 +0000) SOC: 0xa1009300 LC: 0x2040010 PMIC: PCA9451A PMIC: Over Drive Voltage Mode DDR: 3733MTS DDR: 3733MTS M33 prepare ok

Someone please help asap...

Thanks in advance!

Re: frdm-imx93 not booting even with demo images from NXP

I see the same thing in the serial port, i have tried with multiple cables

Re: frdm-imx93 not booting even with demo images from NXP

Hello,

When you are following this procedure, what error do you see in board serial port?

If it cannot go to fast-boot mode, please try with another USB cable.

Best regards.

Re: frdm-imx93 not booting even with demo images from NXP

I got a bit ahead, but not yet into the OS. I think the issue is with the contents of my boot drive, as well as the singleboot binary itself.

Again I need someone knowledgeable about the board to help me with this.

Re: frdm-imx93 not booting even with demo images from NXP

Hi, having the same problem. Tried different images on both windows and Linux, and on different Linux distros. Both EMMC and SD-card is not working

Did you ever figure it out?

Re: frdm-imx93 not booting even with demo images from NXP

Hello,

Which command did you use?

I'm not able to reproduce it.

Best regards.

Re: frdm-imx93 not booting even with demo images from NXP

Hi! I did, yes. It always times out on both windows as well as linux, and on Linux I get a segmentation fault.

Re: frdm-imx93 not booting even with demo images from NXP

Hello,

Did you try to flash it with UUU?

Best regards.

Re: frdm-imx93 not booting even with demo images from NXP

Hello,

What do yo see in serial port? Is able to inter in fast-boot mode?

Did you try with another BSP, version. I'm still unable to reproduce the issue in my side.

Best regards.

Re: frdm-imx93 not booting even with demo images from NXP

Hello,

On the serial port I only see SPL output. It never reaches full U-Boot, so I cannot enter the U-Boot prompt or fastboot mode.

Serial output with the official Rev 4.0 image:

U-Boot SPL 2024.04+gde16f4f1722+p0 (Sep 02 2024 - 10:44:35 +0000)
SOC: 0xa1009300
LC: 0x2040010
PMIC: PCA9451A
PMIC: Over Drive Voltage Mode
DDR: 3733MTS
DDR: 3733MTS
M33 prepare ok

Then there is no further output.

I also tested a rebuilt Flexbuild/U-Boot 2025.04 boot image written to the SD card at 32 KiB offset. The board executes the new SPL, but it stops at the same point:

U-Boot SPL 2025.04 (Apr 26 2026 - 16:21:54 +0000)
PMIC: PCA9451A
PMIC: Over Drive Voltage Mode
DDR: 3733MTS
DDR: 3733MTS
M33 prepare ok

So I cannot enter fastboot mode because it does not reach full U-Boot.

I tested these BSP/images:

1. Official FRDM-i.MX93 Rev 4.0 image:
LF_v6.6.36-2.1.0_images_FRDM_4.0_IMX93

2. My own Yocto build for MACHINE=imx93frdm

3. Rebuilt Flexbuild/U-Boot 2025.04 SPL/container

The official Rev 4.0 and my Yocto build use this boot image hash:

7aba6102e5ec64add632cd6667e77fa3f6886fd72c314e4c01f2964c0fc56a5f imx-boot-imx93frdm-sd.bin-flash_singleboot

UUU also fails before flashing. The board is detected:

MX93 SDPS 0x1FC9:0x014E

but SDPS: boot times out:

Start Cmd:SDPS: boot -scanterm -f imx-boot-imx93frdm-sd.bin-flash_singleboot -scanlimited 0x800000
Fail HID(W):LIBUSB_ERROR_TIMEOUT

This happens on both Linux and Windows, and also after trying another laptop.

I also verified SD boot mode selection: with SD boot mode selected and no SD card inserted, there is no serial output. With the SD card inserted, SPL starts and stops after M33 prepare ok.

So currently the board never reaches U-Boot/fastboot.

Re: frdm-imx93 not booting even with demo images from NXP

I am too facing the same issues, I tried with all the 4 revisions available on the i.mx93 frdm portal,
UUU always throws
Fail HID(W): LIBUSB_ERROR_TIMEOUT (-7)(20.02s)

for flashing into emmc as well as in sd.

Re: frdm-imx93 not booting even with demo images from NXP

I finally managed to get something working.

Used a 32GB SD Card as per spec
Cloned the code from the NXP Yocto link, built the code and flashed in as mentioned in the documentation

Flash it into the card, and boot up as mentioned. This worked for me. I think the problem was the uboot binary in the earlier attempt was meant for the evm and not the frdm.

Re: frdm-imx93 not booting even with demo images from NXP

did you solved it? I got same issue

Re: frdm-imx93 not booting even with demo images from NXP

Hi All,

I got the boards working, apparently there has been a Hardware change made on the FRDM-i.MX93 boards, and if you have an outdated U-boot bootloader (before 2025) then you are going to see this issue.

You can check the U-Boot version in the serial monitor when you either try to boot or flash in the Serial Downloader mode.

Example of old U-Boot version: U-Boot SPL 2024.04+gde16f4f1722+p0 (Sep 02 2024 - 10:44:35 +0000)

Try with this Bootloader, with the below command, it should work for you

imx-boot-imx93-11x11-lpddr4x-frdm-sd.bin-flash_singleboot

UUU command : uuu -b sd_all imx-boot-imx93-11x11-lpddr4x-frdm-sd.bin-flash_singleboot .wic.zst

If the above bootloader did work for you then this is the current yocto i.MX BSP repo with the changes: GitHub - nxp-imx/meta-imx: i.MX Yocto Project i.MX BSP Layer · GitHub

Re: frdm-imx93 not booting even with demo images from NXP

Your U-Boot looks old, apparently there has been a hardware change and and only the version after 2025 will support FRDM-IMX93.

Please refer my above post, to flash the bootloader along with your image.

Hope it works for you

Re: frdm-imx93 not booting even with demo images from NXP

Hi @jventura, @qingyu, @ssb1, @skrimby123

Please try this out.

Re: frdm-imx93 not booting even with demo images from NXP

I´m having the exactly same issue too.

Maybe its a board defect in newer boards?

Re: frdm-imx93 not booting even with demo images from NXP

I have solved this from support.nxp.
In Demo Image Download page, chose version 1.0 insted 4.0, and then using latest uuu to download image to borad

Re: frdm-imx93 not booting even with demo images from NXP

I'm getting same error and UART DEBUG output this:

U-Boot SPL 2024.04+gde16f4f1722+p0 (Sep 02 2024 - 10:44:35 +0000)
SOC: 0xa1009300
LC: 0x2040010
PMIC: PCA9451A
PMIC: Over Drive Voltage Mode
DDR: 3733MTS
DDR: 3733MTS
M33 prepare ok

Re: frdm-imx93 not booting even with demo images from NXP

Sorry I am late.

Yes, that´s probably it. My Uboot version:
U-Boot SPL 2024.04+gde16f4f1722+p0 (Sep 02 2024 - 10:44:35 +0000)

But the link to the right bootload in the post is broken, I can´t download it

Re: frdm-imx93 not booting even with demo images from NXP

Link for the bootloader is not working

Re: frdm-imx93 not booting even with demo images from NXP

Please update the download link for the bootloader. This is still an ongoing issue for many of us and no soultion was found yet.
