Other Parts Discussed in Thread: CC2564
Hello
We are trying to get the CC2564 to work with an Atmel SAMA5d4 xplained ultra board running an embedded Linux (4.4.30) .
We followed your porting guide and changed the gpio ports as well as the serial port in the btpsvend.c file. We changed the paths in the bt-sample and updated the files in the proj folder.
We compiled a new Linux Kernel to get the headerfiles and added:
#Shared Transport Driver
CONFIG_TI_ST=y
CONFIG_ST_HCI=y
#For BlueZ
CONFIG_BT_WILINK=y
in the kernelconfiguration.
We added
tibt {
compatible = “tibt”;
nshutdown_gpio = <37>;
dev_name = “/dev/ttyS1”;
flow_cntrl = <1>;
baud_rate = <115200>;
};
btwilink {
compatible = “btwilink”;
};
to the device-tree file.
We Crosscompiled it with arm-linux-gnueabihf- compiler and installed it in /home/root/ and we put the initscripts-TIInit_6.7.16_bt_spec_4.1.bts script from ServicePack 1.5 into the /lib/firmware of the target device.
We are able to run ./SS1BTPM & ./LinuxSPPM. Initialization works but SetDevicePower() returns an error.
SPPM>1 1
BTPM_Initialize() Success: 0.
DEVM_RegisterEventCallback() Success: 5.
SPPM>9 1
echo 37 > /sys/class/gpio/export

echo 1 > /sys/class/gpio/pioB5/value
BT COMM PORT ("/dev/ttyS1"): -5
DEVM_PowerOnDevice() Failure: -14, Unknown Error.
Function Error.
Did we miss something? Do you have any suggestions?
Thanks for any advice.
Greetings
Marcel
