I'm trying to configure MIPI receiver block as the following(input:RAW12, output:RGB24(24bit)).
There are two minimum values(please see the bold red line: One is 84.42, another one is 121.806...) in the figure.
Which value is correct minimum value?
Please let me know.
BTW,
I'm using ez-usb with v1.3.4 SDK.
Thanks,
Show Lessi'm trying to use the Eclipse to "debug?" the example USBBulkSourceSink but get "gdb --version" error. i had compiled and the img was loaded to the RAM and ControlCenter enumerated as USB3.0 driver successfully. Does anybody have the same problem? What does that trying to tell us? Thanks.
Show LessHow to make it work when CyU3PSpiSetConfig() called repeatedly to change the settings?
the example code as the following, but it not work.
example code:
CyU3PSpiConfig_t spiConfig;
spiConfig.wordLen = 10;
CyU3PSpiSetConfig (&spiConfig, NULL);
CyU3PSpiSetSsnLine (CyFalse);
CyU3PSpiTransmitWords (addr, addrbytecnt);
spiConfig.wordLen = 8;
CyU3PSpiSetConfig (&spiConfig, NULL);
CyU3PSpiTransmitWords (data, DataByteCount);
CyU3PSpiSetSsnLine (CyTrue);

If USB3 HUB is inserted between FPGA and PC, Bulk in transfer can be done normally.
What's wrong?
Show LessDear Sir,
I compile Fx3BootAppGcc project( which is provided by SDK1.33 ) and download it into internal SRAM by control center and after re-enumerate, center show this picture,
app title is "CYpress FX3 USB BulkloopExample Device", is it right?

Dear Cypress,
I would like to use Cypress FX3 CYUSB3014 with GPIF to translate data via 32-bit bus from external peripheral device to USB Endpoint every clock. Is it possible to insert magic word like 0xAAAAAAAA when for example on my additional signal FlagA or something else the rising edge will appeared. In other word I want to implement trigger due to mixing Data with my unique (magic) word?
Data on USB Endpoint
clock cylcle 1 => Data1
clock cycle 2 => Data2
after cycle 2 I assert FlagA to "1" and want to have
clock cycle 3 => 0xAAAAAAA
and after again
clock cycle 4 = > Data3
clock cycle 5 => Data4
Which "action" does this in GPIF designer?
Could you provide any example.
Thank you.
Show LessHi, I am looking to interface some of the Aptina MIPI imagers to the CX3. Has anyone interfaced to the AR0835 8Mpixel imager? I am having trouble setting up the timing GUI to get the imager to send information to the CX3. Does anyone have sample code that allows for setting the AR0835 registers? Thanks in advance for your help.
Show LessHello!
I can't solve the problem with using float in family of printf() functions in my C project.
I use EZ-USB SDK 1.3 with SUPERSPEED EXPLORER KIT.
I want to use sprintf() and vsprintf() (with va_list) for creating debug messages.
But when i add printf() family functions into my project, I receive linker error (picture 1):
Picture 1
I read in different forums, that for using float int printf() there are two ways:
1. Add to my project cyfxcppsyscall.cpp file (with _sbrk definition) and #include <sys/unistd.h> file, where using sprintf().
Also add __heap_start and __heap_end definition in fx3.ld linker file.
It's not work - i also see undefined reference to '_sbrk'
2. Add linker flags: -specs=nosys.specs -specs=nano.specs -u _printf_float

Show LessHi, I am starting withe the CYUSB3KIT-003and the John Hyde book. I try to import Chapter3Example1, I can build the project, but when I try to run it,I get the message "Launch failed, binary not found". When I try to open the .img file, the message is "cannot link, file damaged".I downloaded and unzipped it several times but without result.Can you please help? The PC is a Medion with Win10Pro 64 .
Thanks a lot , Jos
