To help me debug it not working in my Linux system I would like to gain a better understanding of how it works.</P><P></P><P>Does the module come with any firmware after power up? I would like to know if Linux first can read some registers after reset or must it first download firmware into the device before it can test if it is present? I have had a look during a reboot at the oscilloscope at the SDIO interface and the only pin I see activity on is CLK, nothing on Data0:3 or CMD. Do you know what could be going on here?</P></BODY></HTML> Wed, 15 Jul 2020 20:15:32 GMT https://community.nxp.com/t5/Wireless-MCU/Wifi-Chipset-Firmware-Loading/m-p/1051944#M9309 eoin_oconnell 2020-07-15T20:15:32Z Re: Wifi Chipset Firmware Loading https://community.nxp.com/t5/Wireless-MCU/Wifi-Chipset-Firmware-Loading/m-p/1051945#M9310 <HTML><HEAD></HEAD><BODY><P>Hello, </P><P></P><P>By any chance , which device are you using ?
