What’s New
A summary of changes made in each release of this product can be found in the Core SDK Changelog.
Note that the Core SDK follows similar-but-not-always-aligned versioning with the LPF3 SDK. The Core SDK feeds multiple other SDKs, and as such, sometimes LPF3 SDK users will see multiple Core SDK version jumps between releases.
The following table helps users identify which Core SDK was included in each LPF3 SDK, and therefore which Changelog entries to review. Generally speaking larger M.mm version segments will contain the same features/fixes as smaller M.mm versions.

Upgrade and Compatibility Information
There is an incompatibility between the Core SDK device metadata for CC2755R105YCJ and SysConfig 1.24.0. If building for this device, please ensure to use either the version listed below, or SysConfig 1.24.1 or later.
Due to errata SYS_211 there are several impacts to both the APU, CAN, and I2S drivers. See below for a general description, but also make sure to refer to the specific documentation of each driver.
- APU
- No direct memory accesses should be made to APU memory. Instead, use the functions
APULPF3_loadArgMirrored(),APULPF3_loadTriangular(), orAPULPF3_dataMemTransfer().
- No direct memory accesses should be made to APU memory. Instead, use the functions
- CAN
- There are new restrictions on CAN APIs: CAN and MCAN APIs cannot be called from within an interrupt context or a critical section.
- Due to SYS_211, there might be periods up to 45ms long where the CAN driver is blocked from handling incoming messages. Special care should be taken to size the RX FIFO accordingly for this worst-case scenario.
- I2S
- The I2S driver may not be used simultaneously with the CAN or APU driver.

Versioning
This product’s version follows a version format, M.mm.pp.bb, where M is a single digit Major number, mm is 2 digit minor number, pp is a 2 digit patch number, and bb is an unrestricted set of digits used as an incrementing build counter.
Note that sometimes documentation will exclude the bb build segment as during development it’s often unknown what the final build number will be(!), and external releases will all have a unique M.mm.pp.
