CC33xx MCU Package R5 Release Notes
Table of Contents
Introduction
This CC33xx MCU Software Package delivers components that enable engineers to develop applications on the Texas Instruments CC33xx Wi-Fi devices and Sitara family of microcontrollers (MCU).
This software toolkit provides the drivers for CC33xx devices to be used with a Real-Time Operating System (RTOS) on a microcontroller.
This is version R5 of the CC33xx MCU Software Package.
Disclaimer:
The purpose of this CC33xx MCU software package is to provide a prototype for customers to start evaluating AM243x and CC33xx. This is not a fully productized release.

Known Issues
| ID | Summary |
|---|---|
| OSPREY_LDB-2126 | [Thickmac] - Multirole STA/AP with traffic, some stability issues seen |
| OSPREY_LDB-2125 | [ThickMAC]: SUT sometimes fails in stress Connect/Disconnect scenarios |
| OSPREY_LDB-2109 | [ThickMAC] - Scan doesn't always receive all results in Multirole |
| OSPREY_LDB-2108 | [ThickMAC] - Multirole STA/AP, when STA is configured to WPA3, fails |
| OSPREY_LDB-1477 | SSID field in scan results is sometimes empty |
| OSPREY_LDB-1069 | Using wlan_sta_role_down without wlan_disconnect in the network terminal example might cause example to get stuck |
| OSPREY_LDB-953 | “-help” attribute for several commands in the network terminal example shows incorrect text |
| OSPREY_LDB-830 | Using more than two “recv” commands in parallel in the network terminal example may return general error code |
| OSPREY_LDB-781 | Static IP/GW/DNS configuration appears in wlan_connect help although not supported |
| BLE_OSPREY-203 | Osprey LX (Nimble Host) Central might get stuck after scan with duplicate adv reports in congested environment |
