I would have thought this was easy but I cannot seem to find a way to prevent LOG_INF etc from adding a line break to the log string. 

I have found the following log flag definition in log_output.h

#define LOG_OUTPUT_FLAG_CRLF_NONE BIT(4)

But I cannot see how to set this flag in the build and config system so that the logging picks it up.

Thanks,

Justin

Hi there,

 

On the board acting as a Host (i.e. the one that is running the app, not the on running hci_uart) you need to add a chosen node for  zephyr,bt-uart, like here:

 

https://github.com/zephyrproject-rtos/zephyr/blob/main/boards/arm/hexiwear_k64/hexiwear_k64.dts#L29

 

More about zephyr chosen nodes here:

Subject: [Zephyr-users] help with BLE HCI dual chip setup

 

Hello,
I am testing the dual chip configuration of the BLE.
I am using two nrf52dk boards and I would like to setup one as host and one as controller.
I am following the "96Boards Carbon nRF51" sample as a reference.
my goal is to use a uart for the connection between the two boards.
I was able to build the controller part of the code but failed on the host.
I am testing with the peripheral sample project.
in the boards folder I added a .conf and .overlay files for the nrf52dk.
my nrf52dk_nrf52832.overlay file is as follows

&uart0 {
    compatible = "nordic,nrf-uart";
    current-speed = <1000000>;
    status = "okay";
    hw-flow-control;
    tx-pin = <5>;
    rx-pin = <4>;
    rts-pin = <7>;
    cts-pin = <6>;
};

my nrf52dk_nrf52832.conf file is as follows

CONFIG_CLOCK_CONTROL_NRF_K32SRC_RC=y

CONFIG_CLOCK_CONTROL_NRF_K32SRC_XTAL=n

 

CONFIG_SERIAL=y

CONFIG_UART_CONSOLE=n

CONFIG_USE_SEGGER_RTT=y

CONFIG_RTT_CONSOLE=y

CONFIG_LOG=y

CONFIG_LOG_DEFAULT_LEVEL=4

CONFIG_SPI_LOG_LEVEL_DBG=y

CONFIG_LOG_BACKEND_RTT=y

I added the following to prj.conf

# Incresed stack due to settings API usage

CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=2048

 

CONFIG_BT=y

CONFIG_BT_DEBUG_LOG=y

CONFIG_BT_SMP=y

CONFIG_BT_SIGNING=y

CONFIG_BT_PERIPHERAL=y

CONFIG_BT_DIS=y

CONFIG_BT_ATT_PREPARE_COUNT=5

CONFIG_BT_BAS=y

CONFIG_BT_HRS=y

CONFIG_BT_PRIVACY=y

CONFIG_BT_DEVICE_NAME="Zephyr Peripheral Sample Long Name"

CONFIG_BT_DEVICE_APPEARANCE=833

CONFIG_BT_DEVICE_NAME_DYNAMIC=y

CONFIG_BT_DEVICE_NAME_MAX=65

 

CONFIG_BT_KEYS_OVERWRITE_OLDEST=y

CONFIG_BT_SETTINGS=y

CONFIG_FLASH=y

CONFIG_FLASH_PAGE_LAYOUT=y

CONFIG_FLASH_MAP=y

CONFIG_NVS=y

CONFIG_SETTINGS=y

 

# added these to enable the BLE HCI config

CONFIG_GPIO=y

CONFIG_SERIAL=y

CONFIG_UART_INTERRUPT_DRIVEN=y

CONFIG_BT_HCI=y

CONFIG_BT_CTLR=n

the project doesn't build. it gives the following error

error: '__device_dts_ord_DT_CHOSEN_zephyr_bt_uart_ORD' undeclared (first use in this function)

 

any advice on how to fix this or how to get get a dual chip setup to work would be very appreciated.

Thanks

Subject: [Zephyr-users] Using the posix BSP

Stoopid question time again I'm afraid: I would like to run Zephyr
with Linux as host, so using the posix BSP. I can find information
about running a posix application on top of Zephyr but not the other way up.

Can anyone point me at an example or some information concerning how I
go about running Zephyr with its posix BSP?

Hi, I am trying to make an array that would bypass cache. I declare it like this:
volatile __attribute__((aligned(64))) __attribute__((packed)) uint32_t __attribute__((uncached)) buffer[4] = {0}

After the declaration I fill my buffer in a simple for loop:
for(i = 0; i < size; i++) { buffer[i] = i; }

And after compilation for my for loop I get the following asm code:
mov_sr    0,0
mov_s    r14,<buffer_address>
add2    r1,r14,r0
st_s    r0,[r1,0]
add_s    r0,r0,1
brne_nt    r0,<size>,-14

From what I understand about the _uncached_ attribute instead of the st_s command, in my disassembly, I should get st.di.

I found a workaround using pointers, so if I just declare a pointer like this:
volatile uint32_t __attribute__((uncached)) *help = (volatile uint32_t *)(buffer)
and I use it in the for loop instead of the buffer I get the st.di commands correctly.

I am using the zephyr_sdk_0.12.4 version of ARC toolchain.
I don't know if this is the best place to ask this question, but if anyone has an answer for this of can direct me to another list I would very much appreciate that.

Thanks in advance :)
