Dual Core swUpdate - IMX8ULP9EVK

dhruvinrajpura — Fri, 30 Aug 2024 04:58:27 GMT

I am performing OTA(swupdate) in IMX8ULP-EVk9 and I followed docment
https://docs.nxp.com/bundle/AN13872/page/topics/introduction.html
and with this I am able to perform swupdate for A core(Linux) For that sw-description file I am using that I attched here.

Now I am updating A core image in /dev/mmcblk0p2 now I also want to update M core(MCU) side image as well (IMx8ULP is hetrogenius dual core MPU) what I need to add in sw-description file so I can update M core image and specificaly in which partition,

Here is my current partition that I have with minimal core image

root@imx8ulp-9x9-lpddr4-evk:~# lsblk NAME MAJ:MIN RM SIZE RO TYPE MOUNTPOINTS mtdblock0 31:0 0 64M 0 disk mmcblk0 179:0 0 29.1G 0 disk |-mmcblk0p1 179:1 0 83.2M 0 part -mmcblk0p2 179:2 0 318.8M 0 part / mmcblk0boot0 179:32 0 4M 1 disk mmcblk0boot1 179:64 0 4M 1 disk

Can anyone explain that to update image on M core side in which partition I need to add and what needs to be update in sw-description file?

If you are using dual boot bootloader image, the m core image is installed into imx-boot-xxxx bootloader, please refer the AN to update bootloader.

@Zhiming_Liu
Thanks for response,

when I try to upload M core in the bootloader with dtb file and kernel image on

mmcblk0boot0

while booting I am getting dtb file not avilable error, so It is not able to boot further.

How can I ensure that am I flashing in the correct partition or not and do I need to update dtb, kernel and M core image on the same partition or in different partition in sw-description file.

How sw-description file will look like in this case and what will be partition scheme for imx8ulp-evk9 that's main thing I want to know.

The file you need to update is not in /dev/mmcblk0boot0. Please refer the templates in https://github.com/NXP/swupdate-scripts/tree/main/boards.

You can copy config files from i.MX93, the step is replacing file names in these configs.

https://github.com/NXP/swupdate-scripts/blob/main/boards/cfg_imx93_base.cfg

https://github.com/NXP/swupdate-scripts/blob/main/boards/cfg_imx93_update_image.cfg

https://github.com/NXP/swupdate-scripts/blob/main/boards/sw-description-imx93-emmc-dualcopy-image.template

These names are different, and the offset is same as i.MX93(32K) on i.MX8ULP.

Thanks @Zhiming_Liu

I created sw-description file as given in reference and attched here as well, with that when I perform swupdate only A core image is updating on the M core image is still previous one after rebooting.

Can you please check my sw-description and script to generate swu file for that?

I will try that on EVK board.

Thanks @Zhiming_Liu

If you are performing it on evk board please do that with dual copy, because I am performing it as dualcopy swupdate.

If you completes it successfully on evk please share me zip file of that setup, I will re do it on my side as well.

Hi,

If you have tried swupdate on IMX8ULP-EVK9 on both cores(M core & A core), Please let me know so I can reproduce same thing on my side.

Hello @Zhiming_Liu

Thank you so much for help,

Having one issue while performing https://community.nxp.com/t5/i-MX-Processors-Knowledge-Base/Add-imx8ulp-support-in-swupdate-scripts/ta-p/1954610

when I created

./assemble_base_image.sh -b imx8ulp -e emmc -d doublecopy -m

and I created swu_doublecopy_rescue_imx8ulp_emmc_20240916.sdcard and I updated image with

uuu -b emmc_all .\imx-boot-imx8ulp-lpddr4-evk-sd.bin-flash_singleboot_m33 .\swu_doublecopy_rescue_imx8ulp_emmc_20240914.sdcard

getting error while botting board

DHCP client bound to address 192.168.68.138 (26 ms) *** ERROR: `serverip' not set Cannot autoload with TFTPGET BOOTP broadcast 1 DHCP client bound to address 192.168.68.138 (33 ms) *** ERROR: `serverip' not set Cannot autoload with TFTPGET WARN: Cannot load the DT =>

what I changed in your patch is name of dtb as i am using Imx8ULP-EVK9 so first I tried with exact changes you given I got error than I modified dtb name and again tried but still getting same issue

I checked env and got

fdt_addr=0x83000000 fdt_addr_r=0x83000000 fdt_high=0xffffffffffffffff fdtcontroladdr=a3e04210 fdtfile=imx8ulp-9x9-evk.dtb

I tried with imx8ulp-evk.dtb and imx8ulp-9x9-evk.dtb both having same error on boot.

Re: Dual Core swUpdate - IMX8ULP9EVK

Tried that also, but when I try to flash

uuu -b emmc_all .\imx-boot-imx8ulp-lpddr4-evk-sd.bin-flash_singleboot_m33 .\swu_doublecopy_rescue_imx8ulp_emmc_20240914.sdcard

After flashing when I boot up board getting Error to load dt file.

Please check that MBR file has been regenerated, the error relate to partition.

@Zhiming_Liu

I am hittimg command with -m option so MBR will regenerate as written in script

echo "-m Only regenerate or overwrite MBR. This option can be used to generate MBR individually."

echo " Suppose that we don't need to generate MBR every time. Normally we only need to generate it once."

@Zhiming_Liu

IMPORTANT

Apart from dual copy If I just want to update M core image
I applied patch you given for u-boot and generated core-image-minimal.wic file in yocto and flashed it on board.

Than I generated .swu file with
sw-description-imx8ulp-emmc-dualcopy-image.template

where we are including m33 image and bootscript when I update it on web-ui of swupdate,
It is compliting successfully and A core got rebooted but M core is still with previous loaded image it is not updating

Am I missing any step on above?

Re: Dual Core swUpdate - IMX8ULP9EVK

Need to modify here, then bootloader will be replaced. Then you need make sure you are using new M33 firmware.

It's working fine to update M core image,

Do we require any modification in this, because we are putting image of M core from 32K should we go from 0:32K for M core image, May be that's why I am getting error to load dt?
