SWUpdate OTA i.MX8MM EVK / i.MX8QXP MEK

[#1]

Application Note AN13872 
Enabling SWUpdate on i.MX 6ULL, i.MX 8M Mini, and i.MX 93 is available on www.nxp.com 

SWUpdate:

Embedded Systems become more and more complex.

Software for Embedded Systems have new features and fixes can be updated in a reliable way.

Most of time, we need OTA(Over-The-Air) to upgrade the system.

Like Android has its own update system. Linux also need an update system.

SWUpdate project is thought to help to update an embedded system from a storage media or from network.
However, it should be mainly considered as a framework, where further protocols or installers (in SWUpdate they are called handlers) can be easily added to the application.

Mongoose daemon mode:

Mongoose is a daemon mode of SWUpdate that provides a web server, web interface and web application.
Mongoose is running on the target board(i.MX8MM EVK/i.MX8QXP MEK).Using Web browser to access it.

Suricatta daemon mode:

Suricatta regularly polls a remote server for updates, downloads, and installs them. Thereafter, it reboots the system and reports the update status to the server.

Hi, 

I am porting the SWUpdate for iMX8MPEVK and so far it works for dualcopy strategy on the eMMC. However, it does not work for the micro SD card due to the following command inside the emmc_bootpart.sh script (copied to sd_bootpart.sh in my context) : 

mmc bootpart enable 1 1 /dev/mmcblk1

The error : 

[read_lines_notify] : enable mmc(/dev/mmcblk1) boot partition 1

ERROR : ioctl: Connection timed out

ERROR : Could not read EXT_CSD from /dev/mmcblk1

[run_system_cmd] : /tmp/scripts/sd_bootpart.sh command returned 1

ERROR : execute postinstall scripts failed

Installation failed !

Knowing that /dev/mmcblk1 is the micro SD card, /dev/mmcblk2 is the eMMC and  :

Do you have any suggestion on the issue, please ?

sdcard has no boot partition. You don't need the script for  sdcard.  You can remove the script from sw-description.

Technically, this question is not related to the swupdate. It is the knowledge of sdcard and emmc. 

You can roughly treat emmc is a sdcard + 2 boot partitions. 

That is all here. I won't talk about more about emmc. It is not related to this  swupdate topic.

You can read my sharing. But suggest you can read the JEDEC spec for emmc and SD Card Association docs for sdcard/tf card, my documents all come there.

Hi @BiyongSUN ,

It works like a charm by removing the aforementioned script  from the sw-description of dualcopy swupdate on SD card.

Hello, there is no explanation of what these attachments are for. I am porting swupdate to imx8mp, and got lost on how to create a wic file with all the partitions
