To upgrade an existing version, please follow our getting started guide, or use our build script according to your existing kernel.
The WiLink™ 8 software is developed and built using Ubuntu 12.04. Building the package should be possible on any Linux machine, more details can be found in our build process wiki.
This release requires the following software components and tools on the platform in order to function successfully.
All will be automatically packaged using the build-utility scripts.
The WiLink™ 8 software is tested using AM335x-EVM, AM335x-BeagleBone Black with WL1835MOD and WL1837MOD.
The software supports all WiLink™ 8 device family: WL1801MOD, WL1805MOD, WL1807MOD, WL1831MOD, WL1835MOD, WL1837MOD
It can be integrated in a big verity of TI processors such as AM473, J6, AM573 and non TI hosts as well.

Software Limitations
| Bug ID | Description |
|---|---|
| [WILINK8_SW_DEV-555] | Co-Ex: Bluetopia: Any Role: 5G: Lower WLAN throughput while using Bluetopia profile such as FTP and A2DP. |
| [WILINK8_SW_DEV-66] | mesh:iw: some parameters displayed using ‘station dump’ are not updated |
| [WILINK8_SW_DEV-98] | Multi-Role: Connection to APUT during traffic in secured SUT network takes longer than expected (seconds) |
| [WILINK8_SW_DEV-580] | Firmware recovery might occur after long time (>12 Hours) while WLAN running UDP/TCP traffic |
| [WILINK8_SW_DEV-581] | Robustness : Firmware recovery might occur while running extensive connection tests and traffic |
| [WILINK8_SW_DEV-451] | Stability: Co-Ex MR: STA-AP-BT: STA -TCP Rx, AP-TCP Tx, WPA2; BT-eSCO , BT HF might stop after long hours, while WLAN traffic continue |
| [WILINK8_SW_DEV-222] | MR mBSSID: Remote Stations might disconnect, from time-to-time (>10 hours), during TCP Rx |
| [WILINK8_SW_DEV-533] | STA: TCP Bidir: Throughput delta between RX and TX might vary in different modes |
| [WILINK8_SW_DEV-373] | SUT might disconnect while running traffic during intensive BT inquiry with 10 seconds interval |
| [WILINK8_SW_DEV-240] | AP IOP: extSTA disconnects after an inactivity timeout, when any activity is initiated from the STA, while is connected idle |
| [WILINK8_SW_DEV-227] | MR AP+P2P: Variable P2P connection success rate during APUT’s high consistent traffic |
| [WILINK8_SW_DEV-349] | Robustness SG: BT Discovery failed during WLAN consistent high TP traffic |
| [WILINK8_SW_DEV-332] | Stability Multi-role: SUT disconnecting from AP while TCP traffic between SUT to AP and between external STA to APUT |
| [WILINK8_SW_DEV-357] | SUT Connection: Connection with saved profile (only one profile) WPA2, hidden SSID can take about 10 seconds |
