How do I configure the UART's in the OLinuXino Lime using a DTB file? I'm using the image from http://eewiki.net/display/linuxonarm/A10-OLinuXino-LIME.
UART 0 is already configured. This is the relevant part from the DTS file, if I understand correctly:
uart0: serial#01c28000 {
pinctrl-names = "default";
pinctrl-0 = <&uart0_pins_a>;
status = "okay";
};
From http://linux-sunxi.org/Memory_map I can get the memory space for the other UART's. But where do I get the syntax for the pinctrl-0 field, for instance?
Can we configure the hardware with the DTB file only with no need for Allwinner's FEX file?
In an "ideal" situation, should the DTB files be configured by the hardware manufacturer or should they be configured by the developer (is there a manual)?
We can either use Allwinner's FEX file or Open Firmware's Device Tree (DT).
Add these lines to the DT source file (DTS) and compile with dtc.
uart2: serial#01c28800 {
pinctrl-names = "default";
pinctrl-0 = <&uart2_pins_a>;
status = "okay";
};

It seems to be relatively a simple question. I have two mount points on bacula-sd (storage) server- one for local drive and one for s3 bucket (off side backup) and what I need is start two concurrent job at the same time on both drives. So far I have something like that in bacula devices.conf
Device {
Name = "example.prod.com"
Device Type = File
Media Type = File
Archive Device = "/data/bacula/example.prod.com"
LabelMedia = yes
Random Access = yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Maximum Network Buffer Size = 65536
}
Device {
Name = example.prod.com-s3
Device Type = File
Media Type = File
Archive Device = "/mnt/bacula-backup-storage/example.prod.com-s3"
LabelMedia = yes
Random Access = Yes
AutomaticMount = yes
RemovableMedia = no
AlwaysOpen = no
Maximum Network Buffer Size = 65536
}
but it's probably not enough because the job started only on the first device. Do I need disk autochanger or something?
You have to change Media Type = ... parameter to be different for both Devices, i.e.
Device {
Name = "example.prod.com"
Device Type = File
Media Type = File
...
}
Device {
Name = example.prod.com-s3
Device Type = File
Media Type = S3
...
}
It won't work otherwise.
A follow up to this:
one SCDF source, 2 processors but only 1 processes each item
The 2 processors (del-1 and del-2) in the picture are receiving the same data within milliseconds of each other. I'm trying to rig this so del-2 never receives the same thing as del-1 and vice versa. So obviously I've got something configured incorrectly but I'm not sure where.
My processor has the following application.properties
spring.application.name=${vcap.application.name:sample-processor}
info.app.name=#project.artifactId#
info.app.description=#project.description#
info.app.version=#project.version#
management.endpoints.web.exposure.include=health,info,bindings
spring.autoconfigure.exclude=org.springframework.boot.autoconfigure.security.servlet.SecurityAutoConfiguration
spring.cloud.stream.bindings.input.group=input
Is "spring.cloud.stream.bindings.input.group" specified correctly?
Here's the processor code:
#Transformer(inputChannel = Processor.INPUT, outputChannel = Processor.OUTPUT)
public Object transform(String inputStr) throws InterruptedException{
ApplicationLog log = new ApplicationLog(this, "timerMessageSource");
String message = " I AM [" + inputStr + "] AND I HAVE BEEN PROCESSED!!!!!!!";
log.info("SampleProcessor.transform() incoming inputStr="+inputStr);
return message;
}
Is the #Transformer annotation the proper way to link this bit of code with "spring.cloud.stream.bindings.input.group" from application.properties? Are there any other annotations necessary?
Here's my source:
private String format = "EEEEE dd MMMMM yyyy HH:mm:ss.SSSZ";
#Bean
#InboundChannelAdapter(value = Source.OUTPUT, poller = #Poller(fixedDelay = "1000", maxMessagesPerPoll = "1"))
public MessageSource<String> timerMessageSource() {
ApplicationLog log = new ApplicationLog(this, "timerMessageSource");
String message = new SimpleDateFormat(format).format(new Date());
log.info("SampleSource.timeMessageSource() message=["+message+"]");
return () -> new GenericMessage<>(new SimpleDateFormat(format).format(new Date()));
}
I'm confused about the "value = Source.OUTPUT". Does this mean my processor needs to be named differently?
Is the inclusion of #Poller causing me a problem somehow?
This is how I define the 2 processor streams (del-1 and del-2) in SCDF shell:
stream create del-1 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"
stream create del-2 --definition ":split > processor-that-does-everything-sleeps5 --spring.cloud.stream.bindings.applicationMetrics.destination=metrics > :merge"
Do I need to do anything differently there?
All of this is running in Docker/K8s.

Are any other environment variables necessary?
I had successfully communicate single SPI device (MCP3008). Is that possible running multiple (4x) SPI device on raspberry pi 2 with windows 10 iot?
I'm thinking to manually connect the CS(chip select) line and activate it before calling spi function and in-active it after done the spi function.
Can it be work on windows 10 iot?
How about configure the spi chip select pin? Change the pin number during the SPI initialization? Is that possible?
Any smarter way to use multiple (4 x MCP3008 ) SPI device on windows 10 iot?
(I'm planning to monitor 32 Analogue signal which will be input to my raspberry pi 2 running windows 10 iot)
Thanks a lot!
Of course you can use as many as you want (as many GPIO pins).
You just have to indicate the device to which you are calling.
First, set the configuration of the SPI for example, using chip select line 0
settings = new SpiConnectionSettings(0); //chip select line 0
settings.ClockFrequency = 1000000;
settings.Mode = SpiMode.Mode0;
String spiDeviceSelector = SpiDevice.GetDeviceSelector();
devices = await DeviceInformation.FindAllAsync(spiDeviceSelector);
_spi1 = await SpiDevice.FromIdAsync(devices[0].Id, settings);
You can not use this pin in further actions! So now you should configure the output ports using GpioPin class, which you will use to indicate the device.
GpioPin_19 = IoController.OpenPin(19);
GpioPin_19.Write(GpioPinValue.High);
GpioPin_19.SetDriveMode(GpioPinDriveMode.Output);
GpioPin_26 = IoController.OpenPin(26);
GpioPin_26.Write(GpioPinValue.High);
GpioPin_26.SetDriveMode(GpioPinDriveMode.Output);
GpioPin_13 = IoController.OpenPin(13);
GpioPin_13.Write(GpioPinValue.High);
GpioPin_13.SetDriveMode(GpioPinDriveMode.Output);
Always before transfer indicate device: (example method)
private byte[] TransferSpi(byte[] writeBuffer, byte ChipNo)
{
var readBuffer = new byte[writeBuffer.Length];
if (ChipNo == 1) GpioPin_19.Write(GpioPinValue.Low);
if (ChipNo == 2) GpioPin_26.Write(GpioPinValue.Low);
if (ChipNo == 3) GpioPin_13.Write(GpioPinValue.Low);
_spi1.TransferFullDuplex(writeBuffer, readBuffer);
if (ChipNo == 1) GpioPin_19.Write(GpioPinValue.High);
if (ChipNo == 2) GpioPin_26.Write(GpioPinValue.High);
if (ChipNo == 3) GpioPin_13.Write(GpioPinValue.High);
return readBuffer;
}
From: https://projects.drogon.net/understanding-spi-on-the-raspberry-pi/
The Raspberry Pi only implements master mode at this time and has 2 chip-select pins, so can control 2 SPI devices. (Although some devices have their own sub-addressing scheme so you can put more of them on the same bus)
I've successfully used 2 SPI devices in the DeviceTester project and Breathalyzer project within Jared Bienz's IoT Devices GitHub repo.
Notice, that in each project, the SPI interface descriptor is declared explicitly in the ControllerName property for the ADC and Display used in both of these projects. Detailed information around the Breathalyzer project can be found on my blog.
// ADC
// Create the manager
adcManager = new AdcProviderManager();
adcManager.Providers.Add(
new MCP3208()
{
ChipSelectLine = 0,
ControllerName = "SPI1",
});
// Get the well-known controller collection back
adcControllers = await adcManager.GetControllersAsync();
// Create the display
var disp = new ST7735()
{
ChipSelectLine = 0,
ClockFrequency = 40000000, // Attempt to run at 40 MHz
ControllerName = "SPI0",
DataCommandPin = gpioController.OpenPin(12),
DisplayType = ST7735DisplayType.RRed,
ResetPin = gpioController.OpenPin(16),
Orientation = DisplayOrientations.Portrait,
Width = 128,
Height = 160,
};
I am using Apache flume for log collection. This is my config file
httpagent.sources = http-source
httpagent.sinks = local-file-sink
httpagent.channels = ch3
#Define source properties
httpagent.sources.http-source.type = org.apache.flume.source.http.HTTPSource
httpagent.sources.http-source.channels = ch3
httpagent.sources.http-source.port = 8082
# Local File Sink
httpagent.sinks.local-file-sink.type = file_roll
httpagent.sinks.local-file-sink.channel = ch3
httpagent.sinks.local-file-sink.sink.directory = /home/avinash/log_dir
httpagent.sinks.local-file-sink.sink.rollInterval = 21600
# Channels
httpagent.channels.ch3.type = memory
httpagent.channels.ch3.capacity = 1000
My application is working fine.My problem is that in the log_dir the files are using some random number (I guess its timestamp) timestamp as by default.
How to give a proper filename suffix for logfiles ?
Having a look on the documentation it seems there is no parameter for configuring the name of the files that are going to be created. I've gone to the sources looking for some hidden parameter, but there is no one :)
Going into the details of the implementation, it seems the name of the file is managed by the PathManager class:
private PathManager pathController;
...
#Override
public Status process() throws EventDeliveryException {
...
if (outputStream == null) {
File currentFile = pathController.getCurrentFile();
logger.debug("Opening output stream for file {}", currentFile);
try {
outputStream = new BufferedOutputStream(new FileOutputStream(currentFile));
...
}
Which, as you already noticed, is based on the current timestamp (showing the constructor and the next file getter):
public PathManager() {
seriesTimestamp = System.currentTimeMillis();
fileIndex = new AtomicInteger();
}
public File nextFile() {
currentFile = new File(baseDirectory, seriesTimestamp + "-" + fileIndex.incrementAndGet());
return currentFile;
}
So, I think the only possibility you have is to extend the File Roll sink and override the process() method in order to use a custom path controller.
For sources you have execute commands to tail and pre-pend or append details, based on shell scripting. Below is a sample:
# Describe/configure the source for tailing file
httpagent.sources.source.type = exec
httpagent.sources.source.shell = /bin/bash -c
httpagent.sources.source.command = tail -F /path/logs/*_details.log
httpagent.sources.source.restart = true
httpagent.sources.source.restartThrottle = 1000
httpagent.sources.source.logStdErr = true
I am attempting to replicate a SQL CE 3.5 SP1 database but upon syncrhonization, I am thrown the following error:
"Failure to connect to SQL Server with provided connection information. SQL Server does not exist, access is denied because the IIS user is not a valid user on the computer running SQL Server, or the password is incorrect."
I am using the Windows Mobile 6 Professional emulator and the machine I am attempting to connect to is a Windows Virtual Machine running Windows XP Professional SP3. I have configured the network adapter settings for the emulator (I can access web pages), verified user permissions, double checked IIS settings, and triple checked my connection string:
SqlCeReplication rpl = null;
try

// Creates the replication object.
rpl = new SqlCeReplication();
// Establishes the connection string.
rpl.SubscriberConnectionString = #"Data Source = \Program Files\ParkSurvey\ParkSurvey.sdf; Password = *; Temp File Max Size = 512;

// Sets the Publisher properties.
rpl.PublisherSecurityMode = SecurityType.NTAuthentication;

rpl.Subscriber = "ParkSurveySubscriber";
rpl.HostName = "Mobile1";
rpl.CompressionLevel = 6;
rpl.ExchangeType = ExchangeType.BiDirectional;
// Call the replication methods.
rpl.Synchronize();
}
catch (SqlCeException sqlEx)
{
MessageBox.Show(sqlEx.Message);
}
finally
{
// Disposing the replication object
if (rpl != null)
{
rpl.Dispose();
}
}
I have also attempted to open the host machine itself in File Explorer on the mobile emulator and am prompted that "The network path was not found.". This leads me to believe it is ActiveSync issue within the emulator itself. Does anyone have any advice?
Try with IP adresse instead of hostname, and test the agent URL from IE on the device. Make sure to use the latest build of 3.5 SP2 on all components if your DB server is SQL 2012
