Have been running three Ethercat devices with XMC4800 Micro controller, it works perfect. Adding more devices I could get it to work if fourth device is an IO module and the fifth is an Xmc4800 Micro controller but not with more devices.

I have ruled out cabling problems and similar hardware problems since it work perfect with three devices, different devices, different connections and different cables but problem start only then more devices are added. It seems even though message does not arrive back at master, also checked with wireshark values are written to fifth device then checking with debugger.

Then adding more than three devices some error counters increase. I have measured message with oscilloscope it seems device closest to master send message back to master so it seems it get destroyed in some way. Only clue I have is port two is physically connected even though it is not implemented in XMC4800? Anyone else have suggestions? Or got it to work with more devices?

Circuit boards should be ready for small series production, actually already made a few though I have some work left with the enclosure. Show Less

Hi everyone. I have the following issue. I just installed the new version of IDE Modus Toolbox in 2.4.
After going through the entire installation procedure on my Linux Manjaro machine.

My sample applications compile fine, but when I do Debug or Program it throws the following error and does not allow me to program my PSoC6.

Could not determine GDB version after sending: /home/user/ModusToolbox/tools_2.4/gcc/bin/arm-none-eabi-gdb --version, response:

I want to emphasize that I had previously installed the Modus Toolbox 2.3 version and it was working fine

Can you guide me to solve this problem, please?

Hello Infineon,

I'm tring a real CAN comunication test on KIT_A2G_TC397_3V3_TFT board, the receive hardware is ValueCAN3,  the KIT_A2G_TC397_3V3_TFT board send a CAN  message and the ValueCAN3 receive it, but when I ran the code, and set  ValueCAN3 the same baudrate, there is nothing received.  The code as below:

Hi,

I have a project as below:

- CYPD3174 work in no feeback mode.

- MCU read PD contract negotiation from CYPD3174 and set voltage to ACT4751.

1. To disable opto feedback mode, i comment code in condition #if (VBUS_CTRL_TYPE_P1 == VBUS_CTRL_OPTO_FB) as below: 

PDSS_TRIMS->trim_ea1_0 = 0xA0;
/* Use internal current for reference in case of opto feedback. */
pd->ea_ctrl = ((pd->ea_ctrl & ~PDSS_EA_CTRL_IREF_BG_SEL_MASK) |
(1u << PDSS_EA_CTRL_IREF_BG_SEL_POS));

/* Enable shunt */
pd->ea_ctrl |= PDSS_EA_CTRL_EN_SHNT;

Is this the right way to disable feedback mode on CYPD3174, if not please guide me.

2. I added I2C slave (SCB0) but it unable to communicate to MCU until i comment dpm_task(port); in main function.

Please help me add I2C (SCB0) and disable feedback mode of CYPD3174.

 

Thanks and Best regards.

Hi,

I have designed a custom board wherein there are two Infineon IRPS5401  and two IR38063 IC over a common PMBUS.

Two infineon IRPS5401 ICs are getting detected properly, but one of the IR38063 IC is not getting detected at all  and other one says unknown device( Refer attached .png file)

I am using latest version of PowIRCentre GUI with USB005 dongle and an external 12V supply  is being used to power on  the board. The address offset for the IR38063 ICs are 1B and IC respectively.

Followings are the intermediate findings:

1. For both the IR38063ICs, I am correctly getting  outputs on VCC pin (5.18V ) and P1V8  as 1.8V. 

2. The waveform for SCL and SDA looks clean.

Kindly suggest, what could be the possible reasons for this behavior? and what are the further debugging steps?

Hi Teams,

I'm looking for about TC375 iLLD function for MCMCAN example

 

I put values in baudRate sturct like below code.

IfxCan_Can_BaudRate Can00_baudrate = {
(uint32)500000, (uint16)8750, (uint16)3,
(uint16)10, (uint8)13, (uint8)2
};

 g_mcmcan.canNodeConfig.baudRate = Can00_baudrate;

 

but in debugging session(Aurix Developement Studio)

I found value following values 

Name : baudRate
Default:{ baudrate = 4028628992; samplePoint = 769; syncJumpWidth = 2; prescaler = 41248; timeSegment1 = 7 ''; }

 

I think iLLD MCAN doesn't work.

How can i handle it?

Hi Teams,

 

I'm looking for help about MCAN iLLD for TC375

 

I put values to struct of canNodeConfig

 g_mcmcan.canNodeConfig.baudRate = Can00_baudrate; 

 

but values in baudRate struct is wrong

g_mcmcan.canNodeConfig.baudRate = { baudrate = 4028628992; samplePoint = 769; syncJumpWidth = 2;
prescaler = 41248; timeSegment1 = 7 ' ...

Hi,

I'm using "CY8CKIT-145-40XX PSoC® 4000S CapSense Prototyping Kit" for evaluating CapSense capability. 

It's working fine with code example "CE210709_CapSense_Linear_Slider_and_Buttons". But once I add a ADC block in the circuit, Build with error:  "Too many clocks allocated for CSD components. (App=cydsfit)"

Can 4054 have CapSense and ADC work together?

Hello Everyone,

I am running android on imx7d from NXP running Bluetooth+Wifi 1MW module.

I want to run a Bluetooth SPP server on the device. I have implemented the software in C++, Basically an RFCOMM socket. I read Android used Bluedroid instead of Bluez like Linux. But I understand the RFCOMM socket creation method is the same(not 100% sure).

I run the C++ based server software on the imx7d device, it doesn't give any issue creating the RFCOMM SPP port. It creates the port and goes into listening mode. However, when the Android Bluetooth client app running on my phone tries to connect it, It gives the following error in the android bt stack of my imx7d based device.

> [INFO:port_utils.cc(329)] port_find_mcb_dlci_port: Cannot find
> allocated RFCOMM app port for DLCI 40 on 3c:28:6d:2a:b0:28,

I have created the server port on channel 20, but it's not able to find it. I am not sure what exactly is going wrong, I am stuck and not able to find the way to move ahead. Here is the code snippet.

#define BTPROTO_RFCOMM 3

/* BD Address */ typedef struct {
uint8_t b[6]; } __attribute__((packed)) bdaddr_t;

/* ---- RFCOMM sockets ---- */ struct sockaddr_rc {
sa_family_t rc_family;
bdaddr_t rc_bdaddr;
uint8_t rc_channel; };

#define BDADDR_ANY (&(bdaddr_t){{0, 0, 0, 0, 0, 0}})

/* server channel */
#define RFCOMM_SERVER_PORT_NUM 20

void BluetoothSerialPort::openConnection()
{
struct sockaddr_rc loc_addr;
bdaddr_t bdaddr_any = {0, 0, 0, 0, 0, 0};
ALOGE("Start Bluetooth SPP server...\n");

/* allocate socket */
sockFd_ = socket(AF_BLUETOOTH, SOCK_STREAM, BTPROTO_RFCOMM);
if (sockFd_ < 0)
{
ALOGE("Cannot start Bluetooth SPP server\n");
}
memset(&loc_addr, 0, sizeof(loc_addr));
loc_addr.rc_family = AF_BLUETOOTH;
loc_addr.rc_bdaddr = bdaddr_any;
loc_addr.rc_channel = RFCOMM_SERVER_PORT_NUM;

if (bind(sockFd_, (struct sockaddr *)&loc_addr, sizeof(loc_addr)) < 0)
{
ALOGE("socket bind error %s", strerror(errno));
exit(EXIT_FAILURE);
}

ALOGE("Listen Bluetooth SPP server on %d...\n", sockFd_);
if (listen(sockFd_, 2) < 0)
{
ALOGE("socket listen error %s", strerror(errno));
exit(EXIT_FAILURE);
}
}

// Runs the server.
void BluetoothSerialPort::run()
{
struct sockaddr_rc client_addr;
socklen_t opt = sizeof(client_addr);
openConnection();
ALOGE("Listening on Bluetooth SPP server = %d...\n", sockFd_);
/* return new socket for connection with a client */
clientFd_ = accept(sockFd_, reinterpret_cast<struct sockaddr *>(&client_addr), &opt);
ALOGE("connected from %s\n", (char *)&client_addr.rc_bdaddr);
if (clientFd_ == -1)
{
ALOGE("error accepting incoming connection: %s", strerror(errno));
}
else
{

ALOGI("got new connection");
}

// Create a thread and transfer the new stream to it.
std::thread thr(std::bind(&BluetoothSerialPort::readHandler, this));
thr.detach();
}

Can somebody please help? Is there any mistake in the code, it prints the following line "Listening on Bluetooth SPP server" and goes into listening mode.

Thanks much,
Asma
