Tabitha	Replied to Gecko SDK on GitHub Hi Diego, This is very helpful feedback, and I've passed this along internally for consideration. All, If there's any other feedback about what would be helpful in how we distribute the libraries and code, please let us know. As I mentioned, we're continuing to discuss how we can do this in a better way internally, so the more feedback the better! ~Tabi Show more	31 days ago
Tabitha	Replied to Gecko SDK on GitHub Hi all, Unfortunately, this issue is more complicated than just using git to push the SDK releases on Github, as there are several licensing and legal complications. We’re continuing to discuss this internally and will let you know when we have more we can share. ~Tabi Show more	47 days ago

Tabitha	Updated EMU_E110 - Potential Hard Fault when Exiting EM2 or EM3 on Knowledge Base See the Errata sheet for your device to see the complete description of this errata and affected products: www.silabs.com/32bit-errata Affected Devices The following list shows devices that might exhibit the failure mode. EFM32HG, all revisions affected (most recent is B), fixed devices are revision B date code 1751 EFM32LGE, revision E affected, fixed devices are revision E date code 1742 EFM32WG, revision A affected, fixed devices are revision A date code 1742 EFM32ZG, revision A affected, fixed devices are revision A date code 1742 EZR32WG, all revisions affected (most recent is B), fixed devices are revision B date code 1742 EZR32LG, all revisions affected (most recent is B), fixed devices are revision B date code 1742 EZR32HG, all revisions affected (most recent is B), fixed devices are revision B date code 1751 Rev D and earlier do not have the issue Additional Notes Regarding the Failure Mode When exiting EM2 or EM3, some devices may intermittently execute code incorrectly or enter the hard fault handler instead of entering the expected ISR associated with the wake source. The flash is powered down in EM2 and EM3 to save power. Some control registers in the flash can rarely enter an invalid state upon power-on, causing the first read of flash to be incorrect. If this occurs after exiting EM2 or EM3, the core attempts to fetch the interrupt address, but the value will be incorrect and may be invalid. In the case of an invalid value, the core will then jump to the hard fault handler for attempting to execute code from an invalid address. All subsequent reads from the flash are unaffected, and it is only the first flash read after exit from EM2 or EM3 that is potentially erroneous. Software Workaround Installation The attached ZIP file contains software workarounds for each affected device family for the GCC build tools. These workarounds implement the fix for EM2, but the code and methodology is similar for applications using EM3. How the Firmware Workaround Works The firmware workaround relocates the full interrupt vector table to RAM in addition to the peripheral ISRs that are used for EM2 wake-up. When waking from EM2, the core will then jump to the ISR in RAM that performs a dummy read of the flash to clear the potential flash read issue. This method consumes 224 bytes of RAM for Leopard Gecko devices. Note that when using this workaround to address this issue, the system designer must ensure that no interrupts without the dummy read of flash will wake the device out of EM2 and start executing. To be safe, ensure the interrupts that include the dummy read of flash are the highest interrupt priority prior to entering EM2. Additional implementation details can be found in the comments supplied in the workaround source code. For any questions on this issue or the workaround, contact technical support.

Tabitha	Updated to Lacking support from SiLABS Hi all, We've reviewed this internally, and we found there was a gap in the coverage for teams monitoring the Wi-Fi forum. We're correcting this, so threads there should be monitored better going forward. Also, we're in the process of updating the way we monitor all of the forums, so things should get better in all forums over time. Thanks for bringing this to our attention! ~Tabi Show more	Jun 22 2018, 6:43 PM
