PSoC™ 4 Forum Discussions

Hi Community, Simple Question : 

I have a .cyacd file and currently looking at Bootloader Host code to understand how it takes all the data into the Packets and transmit it one by one. I opened the .cyacd file in Notepad++ and saw Hex values. But the cyacd format contains the ASCII ?

Hello 
I added the "ble upgradeable stack" to my application.    I trigger the OTA event using a characteristic.  Everything works fine!  

I do have one issue though.  When I connect, disconnect and then perform a power on reset, the bootloader is triggered and "ota bootloader" is advertised.  This happens even when I don't want to perform an application update.  As per the application note, I've placed these two lines of code in main().  

#if !defined(__ARMCC_VERSION)
             InitializeBootloaderSRAM();
#endif
             AfterImageUpdate();

I cannot share the complete code as it is proprietary.  Anyway,  I feel one of these lines is causing the issue to occur. Any advice is appreciated and let me know if you need more info.

Hello,

I try to program PSoC4 through cyflash and serial interface.
I downloaded and installed the Python version of cyflash from GITHUB.

The cyflash outputs on the screen that sends the following 7 bytes:
0x01, 0x38, 0x00, 0x00, 0xc7, 0xff, 0x17

But on logic analyzer and PSoC bootloader the following bytes are received (6 bytes):
0x7F, 0xEC, 0xFF, 0x71, 0x00, 0x74

Can you please advise what is the problem?

Thanks in advance.

Yacob.

Hi infineon

 

 

Q1)

Can CY8C4045AZI-S413 enter into sleep mode when using an external clock(48MHz) instead of an internal clock?

 

If so, are APIs and procedures the same for entering sleep mode with the internal clock and external clock?

Even with an external clock(48MHz), can device enter sleep mode just by executing only CySysPmSleep() API?

Or does user need to do some other processing if user use an external clock?

 

Q2)

Do you have data on current consumption(typ and max) in sleep mode when the external clock is 48MHz?

The data sheet has data on current consumption for 6MHz and 12MHz, but there is no data on current consumption(typ and max) when the external clock is 48MHz.

 

 

Q3)

Do you have any sample code that CY8C4045AZI-S413 enters into sleep mode?(external clock is 48MHz)

 

 

Best Regards.

Hi, Community,

Let me asked a question about how to set up the UART advanced tab.

I want to set the depth of the FIFO.
In this case, instead of putting a value in Tx Buffer, should I enter a variable in FIFO levels with Interruput enabled and the interrupt source selected as Tx FIFO level?

 

Best Regards,

Hello, We have submitted our medical device to the FDA with all necessary documentation. Our device includes Cypress MCU PSOC4 with BLE (CYBLE-224110). The FDA sent us a request for information (RFI) in which they asked which SDK version are we using? We are quite baffled by this question and don't know what they are referring to. We were wondering if you know what this could refer to in the context of Cypress PSOC 4 related software? Show Less
