Boot real-rime-edge preocmpiled binaries on LS1046ARDB

[jafar30100]

hello
I have downloaded the the edge and baremetal version from:
https://www.nxp.com/webapp/sps/download/license.jsp?colCode=RTESW-V2.8-LS1046ARDB&appType=file1&DOWN...
Extracted the content of archive.

Then extracted the image and flashed to the sd card

zstd -d nxp-image-real-time-edge-ls1046ardb-emmc.wic.zst
sudo dd if=nxp-image-real-time-edge-ls1046ardb-emmc.wic of=/dev/sda1 bs=1M conv=fsyn

 If I try to boot via u-boot with the ocmmand

cpld reset sd

It does not start.

The same procedure with an image obtained with flexbuild successfully loads Ubuntu 20.04. The image was made with:

bld -i mkfw -m ls1046ardb
sudo mkfs.vfat /dev/sda1
flex-installer -i auto -m ls1046ardb -d /dev/sda1

Any idea on what is missing?

Regards

That release did not work but the emmc one did.

$ dd if=./nxp-image-real-time-edge-ls1046ardb-emmc.wic of=/dev/sda bs=1M conv=fsync

Is this possible?

[jafar30100]

Thank you Patrick.

The SD card is ok, I flashed the image but  with the following command (taken from REALTIMEEDGEUG - REALTIMEEDGEUG 1.4.2 - Flashing pre-built images - page 7/404)

sudo dd if=./nxp-image-real-time-edge-ls1046ardb.wic of=/dev/sda bs=1M conv=fsync
$ lsblk
sda           8:0    1  29,5G  0 disk 
├─sda1        8:1    1 166,4M  0 part 
└─sda2        8:2    1   1,5G  0 part

This command gives two partitions, boot and rootfs.

When rebooting the uboot successfully start but can't get the kernel image error occurs:

I have verified image nxp-image-real-time-edge-ls1046ardb.wic.zst with the following command, there is no problem. Please refer to my attached log.

$ zstd -d nxp-image-real-time-edge-ls1046ardb.wic.zst

$ sudo dd if=./nxp-image-real-time-edge-ls1046ardb.wic of=/dev/sda bs=1M conv=fsync

Hello, @jafar30100aarpmahjongg

It seems you’re facing an issue with booting the NXP image on your LS1046ARDB board. The cpld reset sd command should initiate the boot process from the SD card, but if it’s not starting, there could be several reasons for this. Here are a few troubleshooting steps you might consider:

Check the SD Card: Ensure that the SD card is not corrupted and is properly formatted. You can use tools like fsck to check and repair the SD card filesystem.
Verify the Boot Partition: Make sure that the first partition on the SD card is marked as active and bootable. This is typically done using a partition editor like fdisk.
Review U-Boot Environment Variables: Sometimes, the environment variables in U-Boot need to be configured to point to the correct boot device and partition. Use the printenv command in U-Boot to check the environment settings.
Update U-Boot: If you’re using an older version of U-Boot, it might not support certain commands or features required by the newer NXP image. Consider updating U-Boot to the latest version compatible with your board.

I hope this suggestion is helpful for you.

Best Regard,
patrick521f

@patrick521f you are correct.

At the moment the OS image is boot but by the bootloader on the board, hence no core 1 is loaded with the baremetal image.

@yipingwang how can I force the board to boot from the SD card bootloader with the image specified in the first post of this thread?

Regards

[yipingwang]

Please refer to the command in my first post to deploy image to SD card.

Then in u-boot, enter the following command to jump to SD boot.

cpld reset sd

[jafar30100]

I can't see any prompt on uart2 so how may i communicate with core1 and baremetal installation?

After completion of the above mentioned steps, the Linux system boots up on the master core (core 0), and the
Baremetal system boots up on slave core (core 1) automatically.

...

• If the Real-time Edge software is used to compile the Baremetal image, the Baremetal image is included in
the nxp-image-real-time-edge-xxxx.wic.zst. In this case, the master core starts the Baremetal
image on slave cores automatically.

From page 28-29/404 of REALTIMEEDGEUG.pdf

How can I run an application on the slave core?

[yipingwang]

Please use pre-built image in real-time-edge folder in Real-time_Edge_v2.8_LS1046ARDB.zip.

Then refer to section "2.4.2.4 Booting up the Linux with Baremetal" in https://www.nxp.com.cn/docs/en/user-guide/REALTIMEEDGEUG.pdf to deploy image to SD card.
