Hello,

I am performing fx2lp booting in c2load mode.eeprom used is not write protected means the WP pin is connected to ground(same as fx2lp dvk),it means i can load firmware to eeprom.but after firmware is loaded to eeprom,i want to do write protected to eeprom.how can i do this?

regadrs,

Hi,

I cannot get the GPIOs working on my CY7C65211. What I have is:
-a working device configured as I2C + PC side software

-GPIO 11 appearing as "unused" in the Configuration Tool

-GPIO 11 alternatively configured as Driven 0/Driven1/Tristate - no change

-Briefly tried other GPIO ports too

My code line:

     cyret = CySetGpioValue(cyhandle, 11, 1);

always returns CY_ERROR_REQUEST_FAILED. 'cyhandle' is valid, e.g.

CySetI2Config() accepts it.

Is there some GPIO-specific initialisation I need to run?

Should GPIOs be usable when the device is in I2C mode?

Is there any example source code that drive GPIO?

I have thus far only tested on Linux with the latest CyUSB SDK (Feb. 6, 2016), Ubuntu 16.04.

thanks,

Hi,

I have interfaced fx2lp with an image sensor in slavefifo mode.fx2lp is implemented in C2 load.Two eeprom devices are connected trhough i2c to fx2lp with same memory and different address.I have defined endpoint 6 for commiting image sensor data to USB and one more Endpoint 2 BULK IN.Through this endpoint 2,can i write and read data to another EEPROM(Called as data EEPROM),If i do this any disturbance in the endpoint 6 path?because i have to call functions in TD_POLL();please let me know?

thanks,

geetha.

Hello,

i have interfaced fx2lp(cy7c68013A) with an image sensor.the hardware and firmware is working fine.is same  firmware is works fine for fx2lp18 ?with hardware changes according into fx2lp18 datasheet.

Hello!

I've got a problem with the cyusb suite for Linux. The installation went ok. Then the manual says that I should use the "cyusb_linux" command to launch the program, but the terminal responds with the following:

cyusb_linux: error while loading shared libraries: libcyusb.so: cannot open shared object file: No such file or directory

But the file exists, and is in /usr/lib/

What should I do to fix this problem?
 

Hello,

how can we display fx2lp data(imge data) in the control center(or streamer) using direct x and direct show method?

anybody have done it?please let me know.

cypress has any code snipet regarding this host application?

thanks.

Hi,

In the FX2LP TRM,They have given that IFCONFIG.5 (output enable) Bit must not be set to 1 when IFCONFIG.7 is equal to 0 (external clock).what whould be the reason?

Hello,

I have defined endpoint 2 in the fx2lp slavefifo code.I added descriptors in dscr.a51 file as below.

FullSpeedConfigDscr:

;; Endpoint Descriptor

      db   DSCR_ENDPNT_LEN      ;; Descriptor length

      db   DSCR_ENDPNT         ;; Descriptor type

      db   02H               ;; Endpoint number, and direction

      db   ET_BULK            ;; Endpoint type

      db   40H               ;; Maximun packet size (LSB)

      db   00H               ;; Max packect size (MSB)

      db   00H   

FullSpeedConfigDscrEnd:

and also

HighSpeedConfigDscr:

;; Endpoint Descriptor

      db   DSCR_ENDPNT_LEN      ;; Descriptor length

      db   DSCR_ENDPNT         ;; Descriptor type

      db   02H               ;; Endpoint number, and direction

      db   ET_BULK            ;; Endpoint type

      db   40H               ;; Maximun packet size (LSB)

      db   00H               ;; Max packect size (MSB)

      db   00H   

HighSpeedConfigDscrEnd:

and made changes in the slave.c file as below.

TD_Init()

{

EP2CFG = 0xE2; //endpoint2,IN diection

  SYNCDELAY;

}

I have configured endpoint for IN bulk,But firmware Renumerates with bulk out endpoint(0x02).

what whould be the reason?did i miss anything?let me know.

thank you.

Hello,

is keil2 (fx2lp ide)supports release mode (release version build)and debug mode congiguration settings?

thank you.
