Azure Sphere 20.04 update 2 is now available via the retail evaluation feed. This update fixes a bug that prevented ISU features (SPI, I2C, UART) from working in RTApps. If you have RTApps that use these features, please test them against update 2. This update won’t reset the evaluation period.
For more information, read this blog post.
The retail feed will continue to deliver OS update 20.03 until we publish the final 20.04 release during the week of Monday, May 4, 2020. The evaluation release includes an OS update only—it doesn’t include an updated SDK.
If you encounter problems, please notify us immediately through your Microsoft technical account manager (TAM) so that we can address any issues. Microsoft engineers and Azure Sphere community experts will also respond to product-related questions on the MSDN forum.
