Device OS 1.3.1-rc.1 Release Candidate is out on the Web IDE for (Core/Photon/P1/Electron/Argon/Boron/Xenon/A SoM/B SoM/X SoM)
released on August 21st, 2019
Note: This is a Release Candidate (RC) and is not intended for production yet. We've tested this RC to the best of our ability and we want to know what you think now! Please understand that some care and attention is necessary when testing this RC, and be sure to upgrade to the final release when it's available. This RC will not be available by default. To use you must select the version dropdown from the devices drawer. Downgrading back to the current release info is at the bottom of this post.
Note: OTA or YModem transfer on Electron (sequence required)
- First Update to 0.5.5 (if the current version is less than that)
- Then update to 0.6.4 (if the current version is less than that)
- Then update to 0.7.0 (if the current version is less than that)
- Then update to 1.2.1 (if the current version is less than that)
- Then update to 1.3.1-rc.1
Note: DFU over USB on Electron/Photon/P1 (sequence not required)
- You may update to 1.3.1-rc.1 directly first, flash the system firmware (attached above) in order 1,2(,3) to the device using
particle flash --usb <system-part.bin>. See the next note about the bootloader if you are offline!
Note: P1/Photon Bootloader
The Cloud will automatically update the bootloader on P1/Photon devices if your device is online. If your device does not connect to the cloud and it is offline, you should flash the bootloader to the device using
particle flash --serial <bootloader.bin>. This should be done after upgrading system firmware. The Electron bootloader is applied automatically from it's own system parts.
Note: Argon/Boron/Xenon/Argon-SoM/Boron-SoM/Xenon-SoM Bootloader
If your device is offline, the bootloader must be manually updated using
particle flash --serial <bootloader.bin>. This can be done before or after upgrading system firmware.
Note: Downgrading [Electron/Photon/P1] OTA or YModem transfer:
If you need to downgrade, you must downgrade to 1.2.1, then 0.7.0, then 0.6.3(Photon/P1), 0.6.4(Electron) to ensure that the bootloader downgrades automatically. When downgrading to older versions, downgrade to 1.2.1, then 0.7.0 first, then 0.6.3(Photon/P1), 0.6.4(Electron), then to an older version such as 0.5.5.
Note: If your Gen 2 device does not have a Cloud connection, it is recommended to update system firmware, and then the bootloader via CLI with
particle flash --serial bootloader.bin(bootloaders found in Github release). Gen 3 devices should not need an updated bootloader this release.
This release contains v400 bootloaders.
Note: The amount of RAM reserved for the system on Gen 2 platforms increased by at least 1K in this release. This is due to the reorganization of the RAM memory map, which was necessary in order to improve compatibility with recent versions of GCC in future Device OS releases. This memory can be partially reclaimed by rebuilding the application.
Customers affected by #1855 may manually update the Nordic SoftDevice S140 to version 7.0.0 using the binaries provided in this release.
Starting with 1.4.0 Device OS update will automatically trigger SoftDevice update.
particle-cli version 1.43.3.
Upgrading OTA or using YModem (
Not supported in this release.
Upgrading using DFU (--usb only works for SoftDevice, not bootloader yet)
- Upgrade Device OS to 1.3.1-rc.1
- (optional, not required) Update the bootloader to 1.3.1-rc.1 with the OTA or YModem process above
- Put the device into DFU mode (blinking yellow)
- Flash the SoftDevice:
