Now we can modify the source pdo use dpm_update_src_cap() , CCG5 send source capability to device, and we want to know if  there is any function can get the rdo from device

As mentioned in the title, I use Control Center on PC to recongnize CYUSB3014-BZXI device on PCBA and that's OK. 
Here Control Center  is in Cypress's suite for FX3 device.

However, when I power off my PCBA and PC, or just power off PCBA, Control Center occasionally shows no device after power on. On this circumstance, I could only unplug USB3.0 wire and plug it again, and it's OK again.

Add: PC's OS is win10.

It's not OK as follow:

Next it's OK after re-plug.

Hello.

I'm planning to work with the CYUSB3KIT-003.

Reading and following the Kit User Guide,  I am able to complete section 2.1 FX3 SDK Installation using the file ezusbfx3sdk_1.3.5_Windows_x32-x64.

Then next step, 2.4 Superspeed explorer kit installation, is the one not being able to complete. I am using the file SuperSpeedExplorerKitSetup_RevSS obtained from the  CYUSB3KIT-003 design support section.

The installation stops and an error shows up. After clicking "OK " it rolls-back the installation of the items completed.

I would like to get directions to solve this. Its not clear what item is the one that supposedly found a newer version already installed. Anyways, this is right after installing the FX3 SDK, then probably this packet has something newer than the otehr installation is not expecting.

*I tried using the other file available: SuperSpeedExplorerSetupOnlyPackage_RevSS; this one is able to get installed, but then, following the user guide the next step is to use the update manager but this one can not be found, it seems this different package for the Superspeed explorer kit  doesn't include that and other things.

Thank you,

Alan.

I try to debug the example firmware of the Super Speed Explorer Kit USBBulkSourceSinkLED on our custom PCB with a FX3S on it via JTAG. I changed the LED_GPIO define to (49) because our LED is at this pin. I Am using EZ-USB FX3 SDk V1.3.4. on a Windows 10 PC.

For debugging we tried to use the SEGGER Jlink  PLUS Compact with the ARM 14-pin Adapter and  J-Link Software and Documentation Pack v7.96b. We followed the Section 3.1 in the EZUsbSuite User Guide, but without success.

Error Message from EZ USB Suite with JLINK:

 Error in final launch sequence

Failed to execute MI command:

tbreak main

Error message from debugger back end:

Cannot access memory at address 0x40004a00

Cannot access memory at address 0x40004a00

So we build a PCB with a 14-pin JTAG Header and the schematic from the Explorer Kit with the CY7C65215-32LTXI on it to get an integrated Debugger. We configured it like the Explorer Kit using the Cypress USB-Serial Configuration Utility User Guide. We followed the Section 3.7.2 JTAG from the SuperSpeed Explorer Kit User Guide as well as 3.2. Debugging with OpenOCD Section from EZ USB Suite User Guide.

Error Message from EZ USB Suite with CY7C65215:

Error in final launch sequence

Failed to execute MI command:

continue

Error message from debugger back end:

Warning:\nCannot insert breakpoint 1.\nError accessing memory address 0x400040b0: (undocumented errno -1).\nCannot insert breakpoint 3.\nError accessing memory address 0x400040dc: (undocumented errno -1).\nCannot insert breakpoint 2.\nError accessing memory address 0x40004a00: (undocumented errno -1).\n

What does these error messages mean ?

Are there known issues with custom hardware and debugging via JTAG with the FX3S ?

I refer to someone else's project on the Internet, but after loading it in, I found that I can't find any of its header files, how should I add the path to the header files?

The Customer use Host SDK - CYPD6127 to motherboard that support thunderbolt feature.

Could you please give us VIF file?

thank you

Ti gave a link to Cypress telling to download the driver, the link is as follows

https://community.cypress.com/docs/DOC-12366 but the link says it's archived and can't be downloaded

The normal FX 3 driver won't work again, can you share this driver with me?

Hello, 

I want to establish I2c communication between sensor and FX3 device. By taking reference from application note AN7579 what are the changes I need to make into existing firmware if I am using different sensor. Also I am not able to know the I2C clock frequency , please let me know about that.

Any article on this topic or related one would be helpful.

Thanks & Regards,

Akash

Dear Support

As KBA231382, if all buffers are full, "CyU3PDmaMultiChannelGetBuffer()" occurs an error. 

But until "Overrun error", any error isn't occured.

Could you explain why any error isn't occured. 

Hello, I would like to ask what can be done to the Endpoint endpoint to be able to push the data upwards without the need for a manual IN from the PC?
I'm using the FX3 chip, and I've found that in the mouse HID example, it just doesn't need the PC to IN, it just pushes the data up the port via EP1 after a trigger on one of the GPIO ports.

The above is where I have changed the data sent to 0X36 and sent it to the PC. Can you tell me how I can achieve this? I am very eager to solve this problem completely. I hope to get a reply as soon as possible.
