Can not enter system ready test for i.MX8M Mini EVK Board

hankwang — Tue, 31 Dec 2024 05:50:32 GMT

Hey, I want to test system ready on 8M Mini EVK board. I referred to Chapter 4.8 SystemReady-IR in the i.MX Linux User Guide.

First, I downloaded ir_acs_live_image.img from the systemready git website. And flash the image to the EVK board.

Second, I flashed imx-boot-imx8mm-lpddr4-evk-sd.bin-flash_evk to the SD card.

Finally, I inserted the SD card into the EVK board and booted it up.

The information displayed is as follows:

Why can not I enter system ready test?

I have another question. Why does 4.8.3 have Fedora34 and openSUSE Linux distributions installed?

As far as I know, the i.MX operating system is yocto and not Fedora34 and openSUSE.

Hey, when I flash ir_acs_live_mage.img to SD card. The SD card has two partitions. One is BOOT partition. Others is RESULT partition.

Then I flash imx-boot-imx8mmevk-sd.bin-flash_evk to the SD card and the BOOT partition will become an unknown partition.

The instructions are as follows:

1. sudo dd if=ir_acs_live_image.img of=/dev/sde bs=64M;sync

2.sudo dd if= imx-boot-imx8mmevk-sd.bin-flash_evk of=/dev/sde seek=33 bs=1k conv=fsync

Hey, I change the startup method.

I flashed the 8MM EVK BSP to the 8MM EVK board and the device was able to enter the yocto file system.

I flashed the ir_acs_live_image.img file to the USB device. After that, the USB will have two partitions
:BOOT and RESULT.

Then plug the USB device into the 8MM EVK board.

The 8MM EVK board boots up and the bootloader has found the EFI removable media binary file efi/boot/bootaa64.efi.

But the 8MM evk board still goes into the yocto file system and nothing happens.

Then 8MM evk board enter bootlader, I enter "setenv mmcdec 1" then enter "run bootcmd".

Below is my console message:

We not working with Fedora neither with open SUSE, we just have yocto and android if you want linux, also make your UEFI works it apparently bad.

Hey, because I saw in the Linux User Manual Chapter 4.8.3 Linux Distribution Installation that fedora and opensuse need to be install to eMMC.

So how do I install it?

Hi,

Yes, that it's for complete installation of the BSP and has to be like it said. However NXP don't support Fedura or SUSE.

Hey, I followed the instructions to install Ferora. But nothing happened.

Here are my steps below. My EVK is an 8M Mini.

Step 1: Download the IR certificate bootloader. And use an SD card with a boot to yocto file system. Then use the command to flash the bootloader to eMMC.

echo 0 > /sys/block/mmcblk2boot0/force_ro

sudo dd if=imx-boot-imx8mmevk-sd.bin-flash_evk of=/dev/mmcblk2 bs=1k seek=33 conv=fsync

echo 1 > /sys/block/mmcblk2boot0/force_ro

step 2: Download Fedora IoT 41 Image and Burned image to sdcard using rufus tool in windows.

Step 3: Insert the SD card into the 8M Mini EVK board and boot from eMMC.

Step 4: But nothing happens, eMMC still goes to yocto file system.

Attached is a log file.

Do you know what I did wrong?
