CC33xx Linux Package Release Notes

Table of Contents

Introduction

This CC33xx Linux Software Package delivers components that enable operation of the Texas Instruments CC33xx Wi-Fi and BLE family of wireless transceivers on Linux platforms.

This is version 1.0.0.9 of the CC33xx Linux Software Package

The version is a production quality release for 2.4/5Ghz devices

Previous release was 1.0.0.8

Release highlights

This is a release for TI’s CC33xx devices supporting Wi-Fi 6 and BLE 5.4.

Components version:

Enhancement:

  1. Device thermal protection support, enabling operation up to 105C
  2. OTP fuse bits programming
  3. INI updates
  4. Option to pull FW Assert information via host command
  5. Update default BLE TX Power to 10dBm + Add option to configure the BLE default TX power level via INI file
  6. Add negative BLE TX power levels to TX table (-20, -10, -5)

Installer note:

Additional steps needed when installing the CC33xx content in a Processor SDK 9 directory:
The installer inappropriately adds additional folder (cc33xx_linux_package_1_0_0_9) to the destination path. The user is requested to manually move the cc33xx folder to its proper place (e.g from ~/ti-processor-sdk-linux-am335x-evm-9.1.00.001/cc33xx_linux_package_1_0_0_9/cc33xx to ~/ti-processor-sdk-linux-am335x-evm-9.1.00.001/cc33xx)

Resolved Issues

ID Summary

ID Summary
OSPREY_LDB-2048 Power consumption: in 5Ghz band, DTIM 1 current is slightly higher than expected
OSPREY_LDB-1898 [COEX]: External coex - In some cases Wi-Fi connection time is very long during external activity
OSPREY_LDB-1880 TWT - Sometimes Wi-Fi throughput is lower than expected
OSPREY_LDB-1779 Suspend: Does not work with kernel 6.1 and BBB
OSPREY_LDB-1727 IOP-STA - CC33xx connected to Buffalo AP sometimes sends PS polls every beacon
OSPREY_LDB-1638 Some beacon-loss observed when setting LSI to 9 and running UDP RX traffic
OSPREY_LDB-1579 Interoperability: TP-Link Archer C60 AP sends unexpected deauthentication to CC33xx while idle
OSPREY_LDB-1264 IOP STA: Low RX TP with some APs
BLE_OSPREY-206 BLE with 16 connections failed during long run (over 4 hours)
