Product Number: libiio

Software Version: 0.26

Hardware/Software:

AD-PQMON-SL
libiio v0.26
Ubuntu Mate 18.04

Code Snippet:

generate_waveform(1, "voltage0");

#include <stdio.h>
#include <iio.h>
#include <time.h>
#include "function.h"

void generate_waveform(unsigned char chnIndex, const char* chnAttr) {
	
	// Step 1: Enable Channel
	struct iio_channel* chnWaveform = iio_device_find_channel(dev, chnAttr, false);
	
	if (!chnWaveform) {
		errorCode = -3;
		fprintf(stderr, "Error -3: Failed to get channel details at channel Index[%i]:%s\n", chnIndex, chnAttr);
		iio_context_destroy(ctx);
	}

	iio_channel_enable(chnWaveform);

	// Step 2: Create Buffer
	struct iio_buffer* buf = iio_device_create_buffer(dev, BUFFER_SIZE, false);
	
	if (!buf) {
		errorCode = -6;
		fprintf(stderr, "Error -6: Failed to create buffer.\n");
	}

	iio_buffer_refill(buf);
	
	// Step 3: Buffer Cleanup
	iio_buffer_destroy(buf);

}

Error Code:

ERROR: sp_blocking_read_next has timedout
ERROR: sp_blocking_read_next has timedout
ERROR: READ LINE: -110

Troubleshooting Steps That I have taken:

If remove iio_buffer_refill(buf), the coding can run smoothly without error.

Hello,

When creating the iio context, which baud rate and port number are you specifying?

Have you tried running iio_info for your serial context? Could you share the output ?

Thanks,

Cristina

Hi csuteu

When creating the iio context, which baud rate and port number are you specifying?
- Baud Rate: 921600

Have you tried running iio_info for your serial context? Could you share the output?

Update: I tried to increase timeout but error persisted

#include <stdio.h>
#include <iio.h>
#include <time.h>
#include "function.h"

#define TIMEOUT_MS 5000
#define BUFFER_SIZE 1024

struct iio_device* dev; 
struct iio_context* ctx;
int errorCode;

void generate_waveform(unsigned char chnIndex, const char* chnAttr) {
    // Step 1: Enable Channel
    struct iio_channel* chnWaveform = iio_device_find_channel(dev, chnAttr, false);
    
    if (!chnWaveform) {
        errorCode = -3;
        fprintf(stderr, "Error -3: Failed to get channel details at channel Index[%i]: %s\n", chnIndex, chnAttr);
        iio_context_destroy(ctx);
        return;
    }

    iio_channel_enable(chnWaveform);

Hi,

The issue seems to be related to libserialport, one of libiio's dependencies which is responsible for enabling the serial backend. Did you install libserialport via apt or another package manager ? If so, that version is very very old, and there have been numerous fixes since.

On your host computer, could you try the following ?

1. Uninstall the existing libserialport: sudo apt-get purge --auto-remove libserialport-dev

2. Build and install the latest main branch of libserial port :

git clone github.com/.../libserialport
cd libserialport
./autogen.sh
./configure
make
(sudo) make install

3. Rebuild libiio :

cd /path/to/where/you/built/libiio/build

cmake -DWITH_SERIAL_BACKEND=on ../

make

(sudo) make install

Let me know if this fixes your issue.

Thanks,

Cristina

Hi csuteu ,

I didn’t manually install libserialport, maybe it comes with the Banana Pi Ubuntu Mate 18.04 image.

Result: The libiio failed to rebuild.

Hi,

Could you try deleting everything in the build directory of libiio and then do a clean build ?

Thanks,

I'm just realized that I manually downloaded libserialport before based on your suggestion
- (+) iio_info fail detect AD-PQMON-SL - Q&A - Linux Software Drivers - EngineerZone
- However, the latest version I can downloaded is 0.1.1-2, not 0.1.2
