Set/get driver configurations ============================= Path: /debug/btmrvl/config/ gpiogap=[n], hscfgcmd These commands are used to configure the host sleep parameters:: bit 8:0 -- Gap bit 16:8 -- GPIO where GPIO is the pin number of GPIO used to wake up the host. It could be any valid GPIO pin# (e.g. 0-7) or 0xff (SDIO interface wakeup will be used instead). where Gap is the gap in milli seconds between wakeup signal and wakeup event, or 0xff for special host sleep setting. Usage:: # Use SDIO interface to wake up the host and set GAP to 0x80: echo 0xff80 > /debug/btmrvl/config/gpiogap echo 1 > /debug/btmrvl/config/hscfgcmd # Use GPIO pin #3 to wake up the host and set GAP to 0xff: echo 0x03ff > /debug/btmrvl/config/gpiogap echo 1 > /debug/btmrvl/config/hscfgcmd psmode=[n], pscmd These commands are used to enable/disable auto sleep mode where the option is:: 1 -- Enable auto sleep mode 0 -- Disable auto sleep mode Usage:: # Enable auto sleep mode echo 1 > /debug/btmrvl/config/psmode echo 1 > /debug/btmrvl/config/pscmd # Disable auto sleep mode echo 0 > /debug/btmrvl/config/psmode echo 1 > /debug/btmrvl/config/pscmd hsmode=[n], hscmd These commands are used to enable host sleep or wake up firmware where the option is:: 1 -- Enable host sleep 0 -- Wake up firmware Usage:: # Enable host sleep echo 1 > /debug/btmrvl/config/hsmode echo 1 > /debug/btmrvl/config/hscmd # Wake up firmware echo 0 > /debug/btmrvl/config/hsmode echo 1 > /debug/btmrvl/config/hscmd Get driver status ================= Path: /debug/btmrvl/status/ Usage:: cat /debug/btmrvl/status/<args> where the args are: curpsmode This command displays current auto sleep status. psstate This command display the power save state. hsstate This command display the host sleep state. txdnldrdy This command displays the value of Tx download ready flag. Issuing a raw hci command ========================= Use hcitool to issue raw hci command, refer to hcitool manual Usage:: Hcitool cmd <ogf> <ocf> [Parameters] Interface Control Command:: hcitool cmd 0x3f 0x5b 0xf5 0x01 0x00 --Enable All interface hcitool cmd 0x3f 0x5b 0xf5 0x01 0x01 --Enable Wlan interface hcitool cmd 0x3f 0x5b 0xf5 0x01 0x02 --Enable BT interface hcitool cmd 0x3f 0x5b 0xf5 0x00 0x00 --Disable All interface hcitool cmd 0x3f 0x5b 0xf5 0x00 0x01 --Disable Wlan interface hcitool cmd 0x3f 0x5b 0xf5 0x00 0x02 --Disable BT interface SD8688 firmware =============== Images: - /lib/firmware/sd8688_helper.bin - /lib/firmware/sd8688.bin The images can be downloaded from: git.infradead.org/users/dwmw2/linux-firmware.git/libertas/ |
