USB

Hi,

Are there any updates to the CCG3PA stack so that the device can be updated via UART or I2C?

it's ok to flash it once via SWD, but on the field we can't rely on SWD nor CC to upgrade the firmware.

Thanks

Will the CYPD3177 communicate on a 1.8V I2C bus?  The datasheet does not specify a voltage range for the HPI, and neither does the HPI specification document.  Reference designs show 3.3V I2C bus.

Hello,

When I'm trying to write data to Fx3 device from a FPGA device, I always get zero-lengh data transfer despite buffer being full (I know it is full base on the state of DMA flags). I noticed strange behavior of my RDY signal in a middle of a transfer it goes low for some reason and after few clock cycles it goes high (as it should be)

In attachment i'm sending you firmware which I use and state machine from GPIF designer

regards,

Mateusz

Planning to use CCG3PA for a power-sink (consumer role) only.
The board has no other power-sources nor batteries at the time of an type-c ac/dc being plugged in.

1.)
Can't find anything in the official CCG3PA datasheet that states what VBUS_P_CTRL's default state is.
Since the regulator for the CCG's VDDD rail will be post the 'consumer fet', it would be great with some input if this cold-booting ("dead battery") state is supported. 

2.)
Let's assume we would have a local power-source, so that VDDD would already be powered with a 3.3V rail.
Are there more details available on how to handle the fact that VDDD is also an output/regulator coming from the CCG3PA once it sees VBUS. I can see a diode in the block-level schematic in the datasheet but some more details would be great.

Thanks 

Hi,

I am currently working in a project based on CX3. We have developed both an own hardware which embedded it, and a host application.

Our product works as a bridge between MIPI and USB protocols, in order to drive the pixel information from a CMOS Image Sensor to a host.
A complex softwere layer, inside the host, will run after it applying image processing algorithms.

After this overview, I want to explain my doubt. I have been working in both hardware and firmware layers, for this reason I have EZ-USB Suit
installed in my laptop, because I use it to complile the firmware image, which it will be store inside the embedded SPI-Flash memory in the PCB. So, as I have installed the EZ-USB Suite, my laptop has the cypress custom driver which achieve recognize the CX3 as Cypress USB BootLoader. Finally I store the firmware in our hardware design via Control Center tool.

But We need to update the firmware image in whatever laptor, including all of them which do not have the EZ-USB Suite installed. For this reason I would like to know which are the minimum necessary files (contemplated in the SDK EZ-USB Suite) that We need to add in our software layer in order to be able to upload the firmware, discarding the rest of the files of the SDK EZ-USB Suite.

Thanks so much.

Hi. 

Our company want do a Driver Re-sell process.

While reading and following CyUSB.pdf, I have a few questions below.

1. How can I create case for Driver Re-sell?

-   I entered www.cypress.com/support but still I do not know how to do it. 

-  At the previous questions about Driver re-sell, there was a answer that recommend to contact Cypress Local sales/FAE.

 But they also do not know how to do it.

if anybody knows the contact point or mail address about this, please let me know.

2. For the INF file, Should I change the GUID to new one so that have a different GUID with cypress's one?

we just want to change VID/PID for our product without changing any other functionality of the driver.

3. For the prerequisites, the document said we need to prepare below;

  1) EV certificate Code signing Certificate

  2) Microsoft Dashboard Account

  3) HLK studio.

       we have 1), 3) now but I don't know how to get Microsoft Dashboard Account.

        is it the same one with the Microsoft Account which we are using for Microsoft Office 365? or do we need to follow https://partner.microsoft.com/en-US/dashboard/registration/hardware to get Partner Center account?
