WiLink8 驅(qū)動程序隨附了默認的 wl18xx-conf.bin 二進制文件。/lib/firmware/ti-connectivity/wl18xx-conf.bin 會配置所需的射頻參數(shù)、使用的天線數(shù)量，以及所需的工作頻段等。此文件需要根據(jù)設(shè)置中所用的 WL18xx 器件或模塊進行調(diào)整。為了簡化生成 wl18xx-conf.bin（位于 /lib/firmware/ti-connectivity 中）的過程，R8.8 版本中包含可用于根據(jù)硬件配置做出適當選擇的配置腳本。以下各節(jié)詳細介紹了“configure-device.sh”腳本的用法。該腳本將使用所選的選項來更新現(xiàn)有的 wlconf 文件。請注意，編程的值會影響射頻性能，并且需要準確的值才能通過認證。

configure-device.sh 是一個菜單式腳本。該腳本會詢問硬件相關(guān)問題，用于正確配置要與 WiLink 8 器件配套使用的目標。此腳本使用 'wlconf' 實用程序來創(chuàng)建 WiLink8 配置二進制文件。WiLink? 8 解決方案 WiLink8 – wlconf 包含有關(guān)“wlconf”實用程序以及如何修改此配置的更多詳細信息。

首先，完成上述啟動過程并確保 WiLink8 器件已啟動。與目標設(shè)備建立串行連接并以 root 身份登錄。

導(dǎo)航至腳本所在位置 /usr/sbin/wlconf 并運行 configure-device.sh：

cd /usr/sbin/wlconf
./configure-device.sh

該腳本將會向您詢問一系列硬件相關(guān)問題并針對您的系統(tǒng)配置 wlconf。此腳本可用于 WiLink8 TI 模塊、非 TI 模塊或板載芯片設(shè)計。下面顯示了一些示例。

使用 WiLink8 TI 模塊時，該腳本將會自動從 /usr/sbin/wlconf/official_inis 中挑選正確的 INI 文件：

Example for WL1837 without Japanese Certification: 

root@am335x-evm:/usr/sbin/wlconf# ./configure-device.sh

Please provide the following information.

Are you using a TI module? [y/n] : y
