Part Number:AM5728
Tool/software: Linux
Hi all,
We've made a custom board with WLAN module(WL1801MODGBMOCR).And I know from WL18xx Module Hardware Integration Guide that in order to wake up the WL module we need to pull up the WLAN_EN pin using the gpio from AM5728. Now, the problem is we don't use the gpio from 5728,instead,we pull up the WL_EN to the power source directly,however,after rebooting the am5728 in software,we can't detect the wlan module .I've checked the state of the gpio which should connect to AM5728(It's gpio5_7 in dts file) even we didn't use it,The state of gpio change to LO from HI after reboot.
Is it necessary to use the gpio to control the WL module,otherwise,what should I do to fix the problem?FYI,the PLSDK we used is ti-processor-sdk-linux-am57xx-evm-04.00.00.04.And the dts config is showing below.
