Hi Cypress Experts:

I am trying connect camera with ISP to CX3, but no image output.

The ISP output MIPI setting as below:

The CX3 configuration as below:

Could you please help to check whether there is anywhere un-reasonable?

Here is the log:

Is there a USB-Serial Bridge Controller that supports USB3.0?

Or, do you have a plan for that product?

CY7C65213 is USB 2.0 certified, so I just want this 3.0 certified version.

Thanks,

Tetsuo

Dear supports,

we want to use memory in normal operation F/W (280KB) + backup F/W (280KB).

During normal operation, only F/W (280KB) is used. If there is a problem with the F/W in the EEPROM, we would like to be able to boot to the Backup F/W.

(Only one of normal operation F/W or backup F/W)

Currently, we understood that the use of 256KB EEPROM 2EA in FX3 is the limit specification.

However, the EEPROM memory-related restrictions on the FX3 document have not been confirmed and the reason is unknown.

Please answer the following questions.

1. 1. Reason for FX3 + 256K EEPROM 2EA limit specification
2. 2. Whether FX3 and EEPROM can be used as follows.

   1) FX3 + 512KB EEPROM 1EA

   2) FX3 + 512KB EEPROM 2EA

Best Regards,

Tony Kim

I referred AN4053  Streaming Data Through Isochronous or Bulk Endpoints on EZ-USB® FX2™ and FX2LP  

I followed the chapter 2 Associated Project Files, I unable to create hex file and I share the screenshot below

Thanks

Esakki

Please send me link for FX2LP programming guide.

for example:   CPUCS = 0x02;                 //12MHz operation , CPUCS[4:3] = 10.  

                       PINFLAGSAB = 0x08; // FLAGA - EP2EF

for Reference programming guide How to set hex value for clock  or set port ? with explanation

With Regards,

Dear Cypress,

Write data to Storage Port(through FatFs):

I was running the cyfx3_fatfs  example code on FX3S board, where am using write command

FX3S: `write` sample

Above command works fine and able to write raw data to that sample file and by defaults, it writes 20MB data, next what I did was executed the same command

FX3S: write sample1

this time while writing the data I just removed the SD card and it hangs.
Would like to know do we get any error from f_write?
if we are removed the SD card and it is blocking in f_write.

Thanks,

Vijay

Hi

We are working on a solution that involves i2C communication between the XC7A35T-1FTG256C and FX3 DK and are experiencing problems reading data from the FPGA register.

The issue is that the FX3 does not release the Bus after sending the device address followed by a read bit to the FPGA.

The register we are reading from is 0x40 and has one byte of data. The i2C read code is as follows:

CyU3PReturnStatus_t Status;

CyU3PI2cPreamble_t preamble;

preamble.length    = 3;

preamble.buffer[0] = 0xA2; // i2C write address

preamble.buffer[1] = 0x04;

preamble.buffer[2] = 0xA3; // i2C read address

preamble.ctrlMask  = 0x0002;

uint8_t buffer[] = {0};

Status = CyU3PI2cReceiveBytes(&preamble, (uint8_t *)&buffer, 1, 0);

CheckStatus("I2C_Write", Status);

I have attached an image of the results we get from the signal analyzer.

How do we implement the i2C read transaction in such a way that it releases the bus after sending the read address to the FPGA?

Thanks

I want to achieve an interrupt timer, how to achieve it?

I have seen from the data that it can be implemented by GPIO interrupt, but it can't generate interrupt. Here is my code:

//Initialization code:

CyU3PGpioClock_ t gpioClock;

CyU3PGpioComplexConfig_ t gpioConfig;

CyU3PReturnStatus_ t apiRetStatus = CY_ U3P_ SUCCESS;

/* Init the GPIO module */

1. gpioClock.fastClkDiv = 2;
2. gpioClock.slowClkDiv = 0;
3. gpioClock.simpleDiv = CY_ U3P_ GPIO_ SIMPLE_ DIV_ BY_ 2;
4. gpioClock.clkSrc = CY_ U3P_ SYS_ CLK;
5. gpioClock.halfDiv = 0;

apiRetStatus = CyU3PGpioInit(&gpioClock, CyFxGpioIntrCb);

CyU3PGpioComplexConfig_ t gpioComplexConfig;

1. gpioComplexConfig.outValue = CyFalse;
2. gpioComplexConfig.inputEn = CyTrue;
3. gpioComplexConfig.driveLowEn = CyFalse;
4. gpioComplexConfig.driveHighEn = CyFalse;
5. gpioComplexConfig.pinMode = CY_ U3P_ GPIO_ MODE_ STATIC;
6. gpioComplexConfig.intrMode = CY_ U3P_ GPIO_ INTR_ TIMER_ THRES;
7. gpioComplexConfig.timerMode = CY_ U3P_ GPIO_ TIMER_ POS_ EDGE;
8. gpioComplexConfig.timer = 0;
9. gpioComplexConfig.period = 0x00000001; // Reset after each interrupt
10. gpioComplexConfig.threshold = 0x00000001; //Generate interrupt every 125us

apiRetStatus = CyU3PGpioSetComplexConfig(GPIO_ TIMER, &gpioComplexConfig);

if (apiRetStatus != CY_ U3P_ SUCCESS)

{

vJackyTestPrintErr("CyU3PGpioSetComplexConfig failed: %d\n",apiRetStatus);

}
