From a linux system, I want to read back the configured program image from a CYC65215 part and check that its CRC is correct -- assuming it has an appended CRC.  Does the image have a CRC? Is the CRC generated using a known algorithm with  a standard polynomial? If so, which polynomial?

Hello,

I am stuck at a point,
in my application , i use endpoint 2 as slave fifo mode and also use auto in for acquiring data from external peripheral 
endpoint 2 is configured as BULK , quad buffered 
here I make use of REVCTL = 0x03;

whereas i need another endpoint EP4 which i just need to configure as 16 bytes long , and just send communication from host to device using endpoint interrupt .

EP4 is configured as endpoint out , bulk and double buffered 
Now the problem is being caused due to REVCTL register 
The first two transactions are successful , as i arm the endpoint 
But then re-arming of endpoint doesnt work inside the endpoint interrupt 
why is that can someone help me out here ?
this is my code :
void TD_Init(void)
{
EP4CFG = 0xA2; // out endpoints do not come up armed,since the defaults are double buffered we must write dummy byte counts twice
SYNCDELAY;
FIFORESET = 0x80;
SYNCDELAY;
FIFORESET = 0x84;
SYNCDELAY;
FIFORESET = 0x00;
SYNCDELAY;
EP4BCL = 0x10; // arm EP4OUT by writing byte count w/skip.
SYNCDELAY;
EP4BCL = 0x10;

OEC = 0x01; // PC0 as output
EPIE |= bmBIT5 ; // Enable EP4 interrupt

/// For data acquisition

Hi Infineon Community,

I am reviewing the second SPI pinout interface, and I've noticed some discrepancies between various figures and tables regarding the pinout of SPI port 1.

Below, I have included a comparison table and images from Document Number 002-31604 Rev. **, as found on the CY7C65214D-32LTXI webpage. 

I believe the correct pinout is shown in Figure 4, as it represents the actual pinout of the package. Furthermore, Figures 5, 6, and 7 are consistent with Figure 4.

Please confirm if my understanding is correct and make any necessary corrections to the document.

Regards,

Hi,

What is CY7C65210 TID number?

Hello,

Can someone point me to examples codes for using isochronous out endpoints?

apart from the description already in TRM ?

Hello Team,

I apologize for the dumb question.

Long story short: I damaged one of my keyboard's multiplexed lines from a static shock. Upon disassembly I see that it has a CY7C64215-56LTXC microcontroller and was wondering if I can read its flash memory  by using I2C and write it on a new one from Mouser using PSoC 4.

I see the PCB has a header which I'm presuming is the I2C (J1 in the attached picture).

Thank you so much for your help regarding this matter.

Respectfully, 

Moycas.

Hello,

I have a simple project using FX3 (CYUSB3014) and FX3 SDK 1.3.5.

I have Segger J-Link connected to the JTAG pins. Also, have a debug configuration that uses Segger J-Link GDB Server.

I see multiple errors, printed in the Console, like this:

827^error,msg="Dwarf Error: Cannot find DIE at 0x0 referenced from DIE at....

The debugger stops in main. After that, if I continue execution (Run), debugger does not respond anymore - does not stop at any breakpoint, does not allow to pause. I can only terminate the debug session.

If I change the project settings, and switch it to FX3 SDK 1.3.4 - everything works Ok.

It looks like there is something wrong with the pre-built libraries in SDK 1.3.5, as this is the only thing that really changes.

Any ideas how to get SDK 1.3.5 to work with the JTAG debugger?

Thank you,

D.

Hi Experts,

We are using  CY7C65213-32LTXIT (USB Interface IC USB-UART LP Bridge Controller) but USB detection is failed.

We are using Windows11PRO pc.

Can you share us the drivers ?

Thanks & Regards
