Tool/software: Linux
Hi All,
I use WL1835Mod for WIFI function on linux 3.10, currently the sdio_reset returns -110 when the sdio is initializing. I captured the waveform on the sdio bus into the module as below, it seems the command sent from host is correct while the module doesn't give any response. on the hardware, the power is matched with the datasheet , 32KHz clock is running, boot setting is set for operation mode, and I also triggered a high-low-high sequence on WL_EN before the host initialize the SDIO. so what else that I missed? any tips would be appreciated.
B.R.
