Hi all,
I have been pulling my hair on this, and need your advice for what to do
from here.
I use a WL1835 chip on a custom cape, Uart1 is used for bluetooth and mmc2
(mmc1) for wifi. Wifi is ok.
I use the howto from RobertCNelson.
Info:
debian@arm:~$ cat /etc/rcn-ee.conf
distro=Debian
deb_codename=stretch
rfs_username=debian
release_date=2017-12-09
third_party_modules=
abi=aa
image_type=minimal
I have modified the bb-wl18xx-bluetooth script, that is included in the
bb-wl18xx-firmware, so that it toggles the right pins. The pins are defined
in the dts file as led pins as described in the script by Robert. I have
confirmed that the pins are toggled as intended by a oscilloscope.
The uart is setup in DTS file (They are also confirmed to signal when
ordered to :-) )
&uart1 {
pinctrl-names = "default", "sleep";
pinctrl-0 = <&uart1_pins_default>;
pinctrl-1 = <&uart1_pins_sleep>;
status = "okay";
fsl,uart-has-rtscts; // enable flow control
};
The pins are setup:
uart1_pins_default: pinmux_uart1_pins_default {
pinctrl-single,pins = <
0x17c (PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* uart1_rtsn */
0x178 (PIN_INPUT | MUX_MODE0) /*
uart1_ctsn */
0x184 (PIN_OUTPUT_PULLDOWN | MUX_MODE0) /* uart1_txd */
0x180 (PIN_INPUT_PULLUP | MUX_MODE0) /* uart1_rxd */
>;
};
uart1_pins_sleep: pinmux_uart1_pins_sleep {
pinctrl-single,pins = <
0x17c (PIN_INPUT_PULLDOWN | MUX_MODE7) /* uart1_rtsn */
0x178 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* uart1_ctsn */
0x184 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* uart1_txd */
0x180 (PIN_INPUT_PULLDOWN | MUX_MODE7) /* uart1_rxd */
>;
};
The problem is when I run the script:
debian@arm:~$ bb-wl18xx-bluetooth
TI_AM335x_BeagleBone_Customer
Found a Texas Instruments' chip!
Firmware file : /lib/firmware/ti-connectivity/TIInit_11.8.32.bts
Loaded BTS script version 1
texas: changing baud rate to 3000000, flow control to 1
Can't set device: Protocol not supported
Can't initialize device: Protocol not supported
How do I debug this, any advise is appreciated.
Best regards
Ole
