We are working on a project that streams 1936x1552 RAW12 data from IMX623 imager from Sony. I was able to get an image, but only if I set the output pixel clock for the CX3 MIPI config over 100 MHz and the image does not display correctly(on Windows camera app, VLC) and after some time the stream stops and I get a CB Failure.
This is the MIPI config:
CyU3PMipicsiCfg_t null_RAW12_Resolution0 =
{
CY_U3P_CSI_DF_RAW12, /* CyU3PMipicsiDataFormat_t dataFormat */
4, /* uint8_t numDataLanes */
1, /* uint8_t pllPrd */
95, /* uint16_t pllFbd */
CY_U3P_CSI_PLL_FRS_500_1000M, /* CyU3PMipicsiPllClkFrs_t pllFrs */
CY_U3P_CSI_PLL_CLK_DIV_8, /* CyU3PMipicsiPllClkDiv_t csiRxClkDiv */
CY_U3P_CSI_PLL_CLK_DIV_8, /* CyU3PMipicsiPllClkDiv_t parClkDiv */
0, /* uint16_t mClkCtl */
CY_U3P_CSI_PLL_CLK_DIV_2, /* CyU3PMipicsiPllClkDiv_t mClkRefDiv */
1936, /* uint16_t hResolution */
200 /* uint16_t fifoDelay */
};
This is how the image looks:
And the debugging details:
Is this how the Windows Camera app interprets the RAW12 data or is there an issue with the application? Do I need to convert the RAW12 data into another format to get the right colors on the image?
Also do you know why the stream stops after some time and I get the CB Failure? This seems to be influenced by the USB connection, If I use a USB hub I get the error much faster then when I'm connecting directly on the laptop.
Hi support,
I am thinking of configuring the CYUSB3304-68LTXC using an external I2C EEPROM. (MODE_SEL[1:0]=2’b01)
At that time, the polarity of POWER_EN seems to be determined by the EEPROM data, so I am curious about what happens when RESETN=L.
What is the polarity of POWER_EN when RESETN=L?
Best regards,
Koki
Show LessDear Infineonistas,
Looking at the UM_2212_PL91_2301_134027 document titled: “Hardware design guidelines for EZ-PD™ CCG7D in automotive applications”
I was revisting the calculations on pages 39 and 40 and found that in order to achieve the values of the
plant pole-1 fpplant = 1,1kHz the calculation of the Cout is different than the sum calculated in Table 5 on page 39.
Following the data on table 5 the sum Cout = 106 + 5,6 = 111,6 uF
Following the calculation on table 6 Cout must be 85,6 uF for the Ro = Vout/Iout = 5V/3A = 1,67 Ohm
This value of Cout (85,6 uF) is confirmed by the following calculation Plant zero fzplant = 92 kHz
Is there an explanation so I can follow it in my design?
That would be of great help.
Thank you
Jousif
Show LessHello
Customer is planning CX3 to connect their image sensor which has MIPI D-PHY 1.2.
I found the similar to Case as the below link.
https://community.infineon.com/t5/USB-superspeed-peripherals/Question-about-CX3-MIPI-version/m-p/263876#M25050
however, it is not clear to me.
Can CX3 support USB-Bridge interface with image sensor has D-PHY 1.2?
I would like to hear if CX3 can be connected with D-PHY1.2 image sensor? Yes or No?
if yes, is there any additional comment that should consider to connect D-PHY1.2?

Jake
Hi,
I'm currently trying to get the usb-uvc demos (USBVideoClass/UsbVideoClassBulk) from the sdk to work on the CYUSB3014. The issue i'm facing is that it works just fine in usb 2.0 but usb 3.0 is unresponsive (no uvc devices reporting).
i have found this post which seems to have been experiencing the same issue years ago:
The only issue is that their final answer is very vague, something about a frequency setting being wrong... But i can't seem to figure out what they're referring to or where the issue lies.
i've attached the unmodified demo i'm trying to get to work... any ideas?
Hi ,
I need to test the bulk transfer on USB interface bulk-endpoints.For this I am going to use Streamer-Application comes with SDK .
But Application not detecting my device.
So What should I do ?

I'm using CX3 Configuration Tool v2.0 (SDK 1_3_5)
Please tell me what is the difference between the values of the "Parralel data width" parameter: "16-bit Zero Pad" and "16-bit Pack"?
How does CX3 pack pixels in these cases for "Video Input Format" "RAW12" and "RAW10"?
Thanks.
Hi Sir/Mam,
We wish to do configuration for FX3 board with our FPGA which is giving video stream at resolution 3264 * 2448 (active resolution) and 2560 * 1440 (active resolution).
I have previously implemented the design for 1920 * 1080 @ 60 fps by taking reference of application note AN75779, but now I want to check compatibility with higher resolutions as mentioned above. I have few questions regarding that -
1. Is FX3 board compatible to stream video data at 2k and 4k resolution?
2. What is the maximum frame rate at which I can stream video data?
3. what is the maximum resolution supported by the board?
4. How to calculate DMA buffer size for changed resolution and frame rate?
Please guide me for the above questions.
Thanks & Regards,
Akash
Show LessHello,
目前我正在使用cyusb3014进行开发设计,硬件包括PC,cyusb3014,以及FPGA。FPGA 负责写入数据,PC端负责读取数据。我希望当有数据从FPGA端写入时,PC端的上位机可以自动检测到有数据写入,并执行读取动作,而并非通过点击tranxfer_in等类似按钮实现,请问需要怎么操作?
祝好!

Show LessSet EZ-USB Fx3 to a standard UAC device(speaker) with SDK 1.3.5 uac_examples, PC already detected and selected this speaker, but can't send data to it, Fx3 can't receive data from PC yet.
