[参考译文] Linux/WL1837MOD：运行校准器工具以设置 Txpower 时的内核转储

https://e2e.ti.com/support/wireless-connectivity/wi-fi-group/wifi/f/wi-fi-forum/810886/linux-wl1837mod-kernel-dump-when-running-calibrator-tool-for-setting-the-txpower

工具/软件：Linux

您好！

我想设置 WiFi 模块的 Tx 功率、因此我已经按照 processors.wiki.ti.com/index.php/WL18xx_TX_Testing 中的步骤进行了操作。

校准器版本为0.76

我在执行这些步骤期间收到错误消息和内核崩溃。

zcat /proc/config.gz | grep NL80211_TESTMODE
CONFIG_NL80211_TESTMODE = y

ifconfig wlan0 down

/calibrator wlan0 plt power_mode on

Wlcore：加电

在 e2e.ti.com/support/wireless-connectivity/wifi/f/968/t/632611?Linux-WL1831MOD-Changing-TX-power-of-WL1831的文章中也发现了同样的问题

请告诉我我应该如何解决此问题？

谢谢、
