Hi,  we have a TC397X based controller board.  There is a LBPORST error occasionally detected by the Functional Safety software during the power-up cycle.

Can anyone here give me some advice on how to figuring out this issue?

Thanks!

Good morning, everyone. That’s my concern. We are working with Psoc on an automatic night light project. We have the HC-SR04 ultrasonic sensor at our disposal. On Arduino, I have no problem programming this sensor, only I am starting on Psoc and I have a lot of trouble understanding. I am working on the CY8C5888LTI-LP09768-QFN kit. My goal is simply to display on the LCD a number of passages in a corridor. I set 70cm for the measurement trigger, that is, the "Trigger" pulse starts when a movement is detected at less than 70cm, and starts the measurement. I have a constraint that the pulse should last 10us. When I get to that level, I don’t know what else to do... I tried to use a timer, but no result, also a counter but no result either. I am attaching two datasheet of my sensor in question.
Thank you in advance for any help.

Hello all,

Need help on TLE9255W configuration part for Baud rate and DLC,

In datasheet, description  it is mentioned that it can support upto 5Mbps but in SWK_CTRL_2 Baudrate Control register for Bitfield BR maximum it is given 1 Mbit/s.

Baudrate

As mentioned CAN FD Baudrate  can be configured using SPI field BR_RATIO of the register  SWSWK_CTRL_2 but not clear how to configure TLE9255W  for upto 5 Mbits/s in CAN FD through SPI.

DLC

And Same for the DLC in below image it is mention till 8 data bytes above that 4 bit value  0b1000. So how to configure for 64 bytes of data.

Thanks 

Hi,

We are trying to  solve a problem with the BLE system randomly failing while the device is connected to a peripheral and sending data. Upon failure Cy_BLE_GATT_GetBusyStatus()  returns CY_BLE_STACK_STATE_BUSY indefinitely. We have tried to reset the BLE system but it does not advertise or scan after the reset.

Solutions tested:  

• Soft-resetting the BLE stack 
• Called Cy_BLE_StackSoftReset(), the function returns CY_BLE_SUCCESS 
• Checked the state of the stack by calling Cy_BLE_GetState(), the result was CY_BLE_STATE_ON 
• The BLE did not behave as normal as it was not advertising or connecting to any other devices 

• Hard resetting BLE system 
• Called Cy_BLE_Stop() on CM4 with results being CY_BLE_SUCCESS 
• Called Cy_BLE_Start() on CM0+ with results being CY_BLE_SUCCESS 
• Called Cy_BLE_Start() on CM4  with results being CY_BLE_SUCCESS 
• Checked the state of the stack by calling Cy_BLE_GetState(), the result was CY_BLE_STATE_INITIALIZING 
• The BLE did not behave as normal as it was not advertising or connecting to any other devices 

Note: Resetting BLE was tested independently of the busy stack issue by manually triggering the soft and hard resets. 

Any clues as to why the stack is busy in the first place or why the resetting process is not working would be appreciated.

Hi Sir,

please provide WL tool and user manual for reference.

environment : ubuntu 22.04 (x86 64bit)

thanks.

I have two really stressful problems:

1.- I try to use the timers with interruptions, I change the state of a led at a frequency of 1Hz, but it does not do so, the led simply stays on and turns off 100ms every second, and the TLE9879 restarts every 2 seconds even that is not in the code, try commenting the watchdog function, but the error persists, do you think the error is in the configuration of the internal oscillator? Do I configure it manually, I will place a photo of my code and the configuration.

2.- I try to load a new program, but apparently it doesn't because when I reset the chip it still has the old program, apparently it loads successfully but it still has the old program.

thanks for your help
