i.MX93 nxpele: Unknown command 'ele_message'

HH_Mov — Tue, 01 Jul 2025 08:56:22 GMT

I am trying to fuse the SRKs of my i.MX93 evaluation module via the nxpele command line tool, based on i.MX 93 signed and encrypted AHAB image — SPSDK documentation

The communication with the u-boot however does not seem to work for nxpele.

As a reference, I call the "get-info" command, but I see the following on my cmd terminal:

nxpele -p COM3 -f mimx9352 -v get-info
INFO:spsdk.ele.ele_comm:ELE communicator is using 131072 B size buffer at 83800000 address in mimx9352, Revision: latest target.
INFO:spsdk.uboot.spsdk_uuu:setenv stdout serial,fastboot success=True response=
INFO:spsdk.uboot.spsdk_uuu:ele_message 0x83800000 0x20000 0604da17000000001800808300010000 success=False response=
SPSDKError: SPSDK: ELE Communication failed with UBoot: list index out of range

On the u-boot command prompt (via a serial connection to the board) it shows:

Unknown command 'ele_message' - try 'help'

I configured u-boot with CONFIG_AHAB_BOOT=y and CONFIG_CONSOLE_MUX=y.
However it seems that the commands are not present.

I am using a Yocto based image with u-boot based on the meta-imx and meta-karo-nxp layers.

Am I missing a specific recipe/configuration flag/setting ?

Which version of SPSDK package are you using and what's the BSP version(especially the ELE FW version)? Did you use i.MX93 A1 chip revision?

I found the cause of the issue. The u-boot version provided with our karo evaluation board is not branched from the nxp u-boot repository. Therefore the ELE part nxp adds was not part of this repo, thus not part of the generated u-boot image.
