October 18th 2019: Device OS v1.4.2
A new Default Release Device OS v1.4.2 is available now on https://build.particle.io for Core/Photon/P1/Electron/Argon/Boron/Xenon/A SoM/B SoM/X SoM.
This release resolves a critical issue affecting Gen 3 bootloaders in DeviceOS releases 1.2.1 - 1.4.1, which may leave the device in a boot/crash-loop with a faint flickering white LED state.
So far, the issue has been confirmed on a number of Borons only, but other Gen 3 platforms may be presenting it as well.
- [Gen 3] Fixes a boot/crash-loop due to a
POWER_CLOCK_IRQn firing in between the jump into the system firmware from the bootloader #1948
