Hello @Mohan51

In i.MX93 you need the libethosu_delegate.so, that is included in our official BSP, under /usr/lib.

I hope this can helps to you.

Best regards.

Hello @Mohan51

Could you please double check? This is from the i.MX93EVK and BSP 6.6.3:

root@imx93evk:~# uname -a Linux imx93evk 6.6.3-lts-next-gccf0a99701a7 #1 SMP PREEMPT Thu Feb 29 08:37:44 UTC 2024 aarch64 GNU/Linux root@imx93evk:~# ls /usr/lib/ |grep libethosu_delegate libethosu_delegate.so root@imx93evk:~#

Best regards.

@Mohan51 I downloaded the same image as you and I did this procedure:

In the directory you will find these files:

To flash the full image you can set the command:

$sudo uuu -b emmc_all imx-boot-imx93evk-sd.bin-flash_singleboot imx-image-full-imx93evk.wic

Boot the board.
