In September 2013, JEDEC published JESD220B UFS 2.0 (update to UFS v1.1 standard published in June 2012). JESD220B Universal Flash Storage v2.0 offers increased link bandwidth for performance improvement, a security features extension and additional power saving features over the UFS v1.1.
Update Ufs Firmware File
Starting in the Solaris 10 10/09 release, you can create a flasharchive on a system that is running a UFS root file system ora ZFS root file system. A flash archive of a ZFS root poolcontains the entire pool hierarchy, except for the swap and dump volumes, andany excluded datasets. The swap and dump volumes are created when the flasharchive is installed. You can use the flash archive installation method as follows:
Only a JumpStart installation of a ZFS flash archive is supported. You cannot use the interactive installation option of a flash archive to install a system with a ZFS root file system. Nor can you use a flash archive to install a ZFS BE with Oracle Solaris Live Upgrade.
In order to install this update I accessed the secondary node from the pair through the GUI, went to the System Upgrade bit, referred to the downloaded nCore update build-13.0-58.32_nc_64.tgz file locally, and ticked the reboot if successful.
Reverted to a snapshot, and server came up with the old 47.24 build. Unsure if this was related to a wrong update file, I grabbed the KVM download, and tried to use that to upgrade (assuming the nCore download might have been the wrong file for our situation). That one just stopped the process midway through by itself noting a directory didn't exist, so that update is probably not the right one.
Out of further options, I re-ran the nCore update on the node again, only to have it stall on the extraction of data. After looking at it trying to extract the same RPM file for 10 minutes, I hit the stop and close button. No changes were made from the looks of things, and knowing the first run of the update worked, I again kicked off the upgrade, only to now find it stalling at nsvpnc_setup64.exe during the extraction process. After letting that sit for another 10 minutes, I again stopped and closed the process out.
When looking at the log, I found the compiling bit on Python which was the last bit noted in my first GUI install, just prior to the completion of the install, so I'm assuming the install ran to completion, just didn't update the screen on my first run:
Both have the folder and TGZ file (newly uploaded) on them now via means of WinSCP, so kicking off the updates is feasable at this point in time. With how involved this however seems to be, I'm not going to do this just prior to leaving for the weekend.
The issue I ran into wasn't specifically taking the HA configuration into account, but is referring to a problem in the loader.conf file... And THAT problem will remain with every update apparently, since I assume the loader.conf is just recreated during the update process. As the apparent recreation has the referral to the COMCONSOLE hardcoded in, and that entry needs to be removed on our hypervisors, that will cause a problem on every update, making the update process very much NOT straightforward.
I was under the impression it wouldn't be more than updating the secondary node from the GUI, and once that one is back from it's reboot to update the primary node (again from the GUI), which should kick off a HA failover as part of it's update process. Once the primary is back to select to do a failback, or leave things as-is... The document link I posted however goes about the whole process through the CLI. Which is probably needed due to the loader.conf problem.
Seeing I had a day off on Friday I did not want to update the system last Thursday. If anything was going to act up, I'd have 'wrecked' it, and someone else with no knowledge of what exactly I did would have to clean it up.
Then I hit reboot... And the system went down and properly rebooted again. Our secondary node (once I log in to the webpage for it) shows the 58.32 version as being active. So any update edits the loader.conf to the default, which will NOT work on all hypervisor systems. I suspect it's assumed XenServer is the hypervisor of choice for the NetScalers, and I also assume XenServer has no issues in handeling that comconsole bit of the loader, whereas different hypervisors kind of 'choke' on this.
Due to the failover causing a complete disconnect of all users that are currently logged in through the NetScaler, I will not force a failover right now. My colleague who will be in really early tomorrow is going to look at that. Once that is done, the connections then should be made through the now updated node, leaving us free to update the other node tomorrow through the same means.
For ESP8266 modules that have more than 1MB of flash memory (NodeMCU, Wemos-D1) you can build a variant with a universal file system or UFS and store your files there (data, images, commands, etc). There are some special files that you can upload and use to execute actions.
The file editor allows to edit the content of a text file online, save it back to the UFS. By changing the name at the top, it will be saved-as the new name (original file remains unchanged). Changes can be discarded by clicking on the button "Manage File System" to returns to the manager.
Almost any command can be used in the file. However, avoid commands that will make the device reboot, such as: changing Wifi setting, MQTT settings, Templates & GPIO, etc. Commands that triggers reboot will create a boot loop which will force Tasmota to automatically disable autoexec.bat and other settings. See SetOption36 for more details.
Extending file system size on ESP32 is performed through the board_build.partitions setting. There are preconfigured settings for 4M, 8M and 16MB ESP32 devices. The are enabled in platformio_override.ini like for the ESP8266. Comment the standard setting and uncomment the variant you want.
Unlike the file-based WIM format, FFU is a sector-based file container that stores one or more partitions. Sector-based imaging means that FFUs take less time to deploy, but have larger files sizes than WIMs. See WIM vs. VHD vs. FFU: comparing image file formats for information about the differences between image formats.

dfu-util is a host side implementation of the DFU 1.0 andDFU 1.1 specifications of the USB forum.DFU is intended to download and upload firmware to/from devices connectedover USB. It ranges from small devices like micro-controller boardsto mobile phones. Using dfu-util you can download firmware to yourDFU-enabled device or upload firmware from it. dfu-util has beentested with the Openmoko Neo1973 and Freerunner and many other devices.
The program dfu-suffixcan be used to add, check or remove a DFUfirmware file suffix, recommended for safely matching a firmware fileand device. The program dfu-prefixcan be used with TI LMDFU/Stellaris or NXP LPC file formats.
This is the default mode for the switch. The INSTALL mode uses a package-provisioning file named packages.conf in order to boot the switch. In addition, there are a number of .pkg files in the flash.
In order to begin the upgrade process, download the IOS XE .bin file from the Cisco web site and place it in the flash of your active switch. The process that is used in order to copy the file to the switch is not covered in this document.
Residual files remain in the flash from previous versions. To clean up the residual files, enter the software clean command instead of a manual deletion of the files. This purges the files that the switch no longer needs.
There are instances when the packages.conf calls files no longer exist in flash. You can manually boot an image from the switch: prompt file; however, upon reload it calls the packages.conf file again and fails to boot.
If this occurs, Cisco recommends to back up the current packages.conf file and rename it or delete it. This process is mandatory, as the next step fails if a .conf file already exists.
We are trying to update the FW of our modems that are embedded in a Linux driven system. There is no way to connect to a windows machine in order to carry out an update via the official QFlash tool. So I have identified the FOTA update as the only reasonable choice. Further more, I would like to use the FW update method via a file uploaded in the file system of the modem.
I tried increasing timeouts in the program, but that was of no effect. Could it be that we are using wrong firmware? I tried with the following with the same result:BG96MAR02A07M1G_01.016.01.016.zipBG96MAR04A04M1G_01.004.01.004.zip
Many of today's popular controller boards ship with a bootloader capable ofupdating firmware via SD Card. While this is convenient in manycircumstances, these bootloaders typically provide no other way to updatefirmware. This can be a nuisance if your board is mounted in a locationthat is difficult to access or if you need to update firmware often.After Klipper has been initially flashed to a controller it is possible totransfer new firmware to the SD Card and initiate the flashing procedurevia ssh.
The procedure for updating MCU firmware using the SD Card is similar to thatof other methods. Instead of using make flash it is necessary to run ahelper script, flash-sdcard.sh. Updating a BigTreeTech SKR 1.3 might looklike the following:
The above commands assume that your MCU connects at the default baud rateof 250000 and the firmware is located at /klipper/out/klipper.bin. Theflash-sdcard.sh script provides options for changing these defaults.All options can be viewed by the help screen: 2ff7e9595c
