Hi
I am trying to enable the bt wilink in Android Jacinto6 EVM Platform with wilink 1837.
I have modified the dra7-evm-common.dtsi file for uart3. Please find my modification as below.
&uart3 {
pinctrl-names = "default";
pinctrl-0 = <&spi2_pins_default>;
status = "okay";
fsl,uart-has-rtscts;
/* bluetooth - TI WL1837 */
kim {
compatible = "kim";
/*
* FIXME: The following is complete CRAP since
* the vendor driver doesn't follow the gpio
* binding. Passing in a magic Linux gpio number
* here until we fix the vendor driver.
*/
/* BT_EN: GPIO_5-4_BT_EN */
nshutdown_gpio = <164>;
dev_name = "/dev/hci_tty";
flow_cntrl = <1>;
baud_rate = <115200>;
};
btwilink {
compatible = "btwilink";
};
spi2_pins_default: spi2_pins_default {
pinctrl-single,pins = <
0x3C0 (PIN_INPUT_PULLUP | MUX_MODE1) /* spi2_sclk.uart3_rxd */
0x3C4 (PIN_OUTPUT | MUX_MODE1) /* spi2_d1.uart3_txd */
0x3C8 (PIN_INPUT_PULLUP | MUX_MODE1) /* spi2_d0.uart3_ctsn */
0x3CC (PIN_OUTPUT | MUX_MODE1) /* spi2_cs0.uart3_rtsn */
>;
};
spi2_iodelay_ds_uart3_conf: spi2_iodelay_ds_uart3_conf {
pinctrl-single,pins = <
0x8A0 (A_DELAY(561) | G_DELAY(0)) /* CFG_UART3_RXD_IN */
0x8A4 (A_DELAY(0) | G_DELAY(0)) /* CFG_UART3_RXD_OEN */
0x8A8 (A_DELAY(0) | G_DELAY(0)) /* CFG_UART3_RXD_OUT */
0x8AC (A_DELAY(588) | G_DELAY(0)) /* CFG_UART3_TXD_IN */
0x8B0 (A_DELAY(0) | G_DELAY(0)) /* CFG_UART3_TXD_OEN */
0x8B4 (A_DELAY(0) | G_DELAY(0)) /* CFG_UART3_TXD_OUT */
>;
};
};
But after this modification kim is not getting loaded.
st_drv.ko module is inserted successfully
Any idea here to proceed further?
Best Regards,
