I have CX3RDK kit with OV7251 sensor. OV7251 is VGA and Black and white ( RAW10 bit)
I added ov7251 init code for I2C write. I2C write is looks good, because read back value almost same.
But eCAM viewer has [ Resolution : 640x480 ] but, FrameRate: 0.0 fps... and Screen is Black.
And windows can find USB video device.
When I cover my hand up OV7251. Mipi data looks changed. so I think sensor is working.
And My project file come from cycx3_uvc_ov5640 sample file.
when i checked trouble shooting doc.... "check... glDMATxCount is zero (0) "
but when I change ov7251 sensor MIPI_CTRL ( Clock Lane gate enable = Gate clock lane with no package to transmit )
I can see CX3_DMA_RESET_EVENT repeatly.
Could any one give me an answer what problem causes the machine display black view?
my system; USB2.0 ( not a USB3.0)
Show LessHi all,
I'm trying to interface an FX3 with an Android device, and I'm getting an HBTERM interrupt, whose handler generates a RESET event and clear the internal buffers. The RESET event and clear buffer actions causes the FX3 to go into stall, and it takes some ~10s to resume streaming when this arrives. I can't find anywhere in the documentation which condition leads to the HBTERM interrupt being raised, how does this relate to the USB 3 protocol, and what actions should be taken. Does anyone have any insights on why this happens?
What I can see on my side, is that it seems to happen after a few RETRY events. And secondly, commenting out the code in the HBTERM handling function so as to not launch the RESET event and not clear the internal buffers, it seems that we get more RETRY events, but we're able to stream correctly eventually, without the ~10s penalty when the RESET and clear buffer actions are performed.
Setup:
CYUSB3KIT-003 FX3 development board.
Open-Q™ 845 HDK Development Kit for Snapdragon 845 running with Android 9 in developer mode (Connection via the USB-C connector on the SDA845 board)
We're using asynchronous bulk transfers, and we're able to reproduce this behavior with the cyfxbulksrcsink example firmware in the Cypress FX3 SDK v1.3.4.
Best regards,

Show LessHi.
The circuit was designed using TI's TMS320F28377 and Cypress's FX3S (CYUSB3035).
Writing and reading S-Port (eMMC) data via USB succeeded.
However, it failed to write data to the eMMC through TI's TMS320F28377 16-bit Data Bus.
If you have a source file for my reference, please help me.
Thank you.

We want to ask the Sony IMX230 camera module by programming a computer using python or C++ .
On the other hand, Can connect to the Raspberry Pi? Has a camera adapter board been produced for IMX 230 sensor?
Please provide the specific usage models.
I look forward to your response. Thank you.
Show LessWe use CYUSBS236, both channels are configured to UART mode, CDC protocol (in our final product we actually use vendor protocol via libusb, but it doesn't matter -- the problem is easily reproducible in CDC mode as well).
The problem is: when the parity setting is configured to Mark or Space AND parity bits in the incoming stream are incorrect, we do NOT receive any notifications from CYUSBS236 about parity errors. It seems like parity bits are just NOT CHECKED in Mark or Space mode. Note, that with Even or Odd parity everything works as expected (parity bit incorrect -> parity error notification).
It this a known bug? What can be done to fix the issue? Any hardware/firmware updates, workarounds?
Thanks!
Show LessI’m having some trouble with the cypress 65215A chip. If I program it to be in I2C mode on SCB0, either master or slave, the 215A will hold the SDA and SCL lines low until a USB cable is connected between the board and a PC, and then the cypress will release these lines. You can then remove the USB connection, and the 215A still lets the I2C lines float.
I have found that programming the cypress into UART mode prevents this problem – the 215A won’t hold the I2C lines (pins 28 and 29) low.
Do you have any idea what’s going on?
Show LessFor confirmation just in case, about the description of attached Reset Pin, Is the red circle 200ms correct? In the English document, it is described as 200 us.

Show LessWe are using cypress for a 32 bit system. Now we upgraded to win10 64 bit system. Now the problem that we found on USB driver. While we use the 32 bit system, it is working fine. whereas in win 10 64 bit, it was not. We were unable to find the USB driver for the 64 bit system. We need cyUSB3.sys, .inf, .dll files too in order to get the output. kindly help me.
Show LessHi ,
I want to test the cy7c68013a's throughput speed. I found the AN4053 is helpful ,but my computer is working in windows 10. Where can I find the windows 10 driver for the AN4053.
Waiting for your answer. Thanks a lot.
