Hello Cypress Community,
I have some problem with EZ USB IDE on Linux,
On fresh install, I'm able to create/import projects and compile it,
But if I restart workstation, IDE loose connection with toolchain and libraries and I'm not able to build project.
Work around that I found is to delete all folders (IDE folder and SDK folder) and install it again. after this IDE is working again until next restart.
May be someone have solution for this because it's annoying to reinstall SDK after each restart.
Regards,
Sergiu
Hi, I'm using CYUSB3KIT-003 and I implemented the syncronous Slave with state machine of the AN65974 example (32bits). The problem is with some bits of the GPIF II have an offset around 1.2V and the FPGA can't detect the zero level. For some reasons it is influenced with the presence of the watermark flag. The bits afected isn't the same with another FX3.
Do you have any idea what is going on?
Show LessHello!
I had several problems debugging FX3:
1.FX3 receiving data Error in CyU3PDmaMultiChannelCommitBuffer: code 71?
2.FX3can transfer 4Kraw16@30fps?
thanks!
Show LessOv5640 library is closed source. How do we control the gain of ov5640?
Hello.
I downloaded the example UVC+CDC (Cx3UvcOV5640_UVC_CDC).
This is a very good example
But there it is made through DMA. I don't control the UART transferring.
And the message from one COM-port is immediately sent to the second one.
I need to send a message through a virtual com-port when I click my button (for example, one byte).
Suggest, how to do it right?
Show LessRegarding the SRAM(16M)CY7C10620V33 on the CYUSB3KIT-003 board.
Please tell me the purpose of use.
If they will design their board, is it necessary to put on their design?

Show LessCurrently we are testing data capture with Cypress FX3, via customized firmware slavefifosync and host application streamer. Generally we may get 15.9MB/s throughput, but when the streamer doesn't run fast enough or other reason, we need to reset FX3 board. Following FX3 TRM document, call CyU3PDeviceReset(CyFalse), FX3 board can return to bootloader mode, we may load firmware again. But FX3 only can run 8MB/s, then drop data quickly. Hard reset manually always can recover FX3 board to normal status.
Do anyone know what else operation is needed to do before device reset? Appreciate any suggestion.
Thanks,
Joe
Show LessHi, Sir
I use fx3 as the uvc device, but after working for a while, the image will be abnormal.
Does anyone know how to fix it?
Thank you very much.
Show LessHello!
I see example "cyfxuartlpregmode"
I could not make it workable
determine the speed 115200, transfer to UART, I expected answer, but it absent.
What is it?
Or tell me how to correctly make UART a loop back (echo)
I'm using WIN7
Many stanks
