Hello.
I'm trying to enable VCONN for CY4532.
I changed the hardware by the method of the link below.
I also changed the firmware.
But the build is failing.
You will see an error message like the one pictured below.
If the build method is wrong, please tell me how.
thank you.
Show LessMy customer Kontron need to have the code sources of the firmware of the Power Delivery CYPD5225 to recompile it.
Please could you provide this firmware
Show LessDear Support Team,
My company has brought a CY4541 Evaluation-board with a daughtercard with the CYPD4225-40LQXIT on it.
We were interessted if the Daughtercard would be working with a CYPD4126-40LQXI instead and ran into a problem.
We exchanged the chip on the daughtercard to check if only one of the board of the baseboards would still be able to convert DisplayPort Signal to USB-C, which was not the case.
Regarding this we have tried to create a firmware based on the example project("CYPD4126-40LQXI-notebook.cydsn") provided by the "PoC Creator 4.4" programm.
Sadly we weren't even able to build the example as it drops errors while building (Post-build?) which we haven't been able to fix ourselfs.
The Output/Error log file is in the Attachment.
Is there a Stockfirmware for the CYPD4126-40LQXI which we can use or could you provide us guidance on how to build a firmware using "PoC Creator 4.4"?
Thank you in advance.
With best regards.
Show LessWe get a ton of USB-C devices and gadgets, yet we only have few USB-C ports.
What is it with USB-C that makes it so expensive to add lots of ports to PCs and laptops?
-
There appears to be only one USB-C hub on the market with 4 ports and it only manages 5GBit/s.
-
AM4 mainboards with a meagre two USB-C ports (that's the maximum you can buy!) cost 200€ minimum whereas other AM4 mainboards start at 25€.
-
A PCIe card that adds four USB-C ports to your PC costs a cool 160€.
-
The cheapest laptop with 4 USB-C ports costs 1150€ and is made by Apple, the company known for their $1000 monitor stand and the $500 tower PC wheels.
Is there hope that USB-C ports will be plentiful and affordable soon?
Show LessI'm trying to program a dongle CCG3 using EZ PD configuration utility and CY4531 using the USB C connector but I can't get it to work. Is there a special FW I need to program onto the CCG3 EVK to allow it to follow figure 14 on the EZ PD programming guide?
Show LessHello,
I'm designing a board to allow the connection of a external monitor through DisplayPort and a USB SS device through the same USB Type-C connector (block diagram below).
For such a board I'm thinking of using CCG3, exploiting USB Type-C Alternate Mode DisplayPort with pin assignment D, thus two lanes for DisplayPort (ML0 + ML1) and two lanes for USB SS (SSTX + SSRX).
I'm deriving the design from the reference EZ-PD CCG3 USB Type-C to DisplayPort Cable Solution but I guess some modifications need to be applied to the CCG3 FW configuration through EZ-PD Configuration Utility, for instance
- AMA VDO, USB version to be set to [USB3.1]Gen 1 Gen 2 and USB 2.0 instead of original USB 2.0 Billboard only?
- SVID Configuration > SVID 0 to be changed with respect to original 0x1005. In case, to which value?
- Alternate Mode > Alternate Mode 0: SVID to be changed with respect to original 0xFF01. In case, to which value?
- DP Mode Parameters > Modes supported: change to D with respect to original E?
- DP Mode Parameters > Preferred DP Mode: change to Multi-function DisplayPort?
One more thing: due to shortage, CYPD3120 is not available. Only CYPD3125 can be found.
Considering the FW needs to be changed anyway, should I go with CYPD3125 even if it is main application is Notebooks, Smartphones?
Any thought or feedback would be really appreciated!
Thank you!

Hello
The EZ-PD ™ Protocol Analyzer Utility is currently using the latest version (v3.1.0). However, in the customer's PC environment, it is prohibited to immediately upgrade JAVA to the 64-bit version, so we would like to temporarily use the PD2.0 compatible CY4500. However, it seems that the PD2.0 compatible (.ccgx) EZ-PD ™ Protocol Analyzer utility cannot be downloaded already. Is it possible to share the old one.
Best Regards

I want to know if there is a development board/evaluation board for EZ-PD CCG6 or chips like CYPD6125-40LQXIT and also what kind of software support is provided for it.
Show LessWhile testing the CYPD 5126 in our equipment I've come across an issue with the overcurrent shutdown: as described in the code the overcurrent shutoff should be set in
system_vbus_ocp_en(port, current, callback)
to the nominal current setting times a factor given by
PD_GET_PTR_OCP_TBL(port)->threshold,
which is set (by default) to some 130% of the nominal current.
However, the system (which currently is set to 3A max current) shuts down at some 3.06 to 3.08 Amps, so "spot on" the nominal value, while, given the amount of overcurrent allowed by ...->threshold, it shouldn't switch off until around 4A.
Resistor is 1% within specs and wiring isn't an issue as well. The behaviour has beeen confirmed by both my test setup and the first batch of samples.
So, my very wide shot at this: is it possible that the chips are accidentally calibrated with the ...->threshold factor in place? So that the actual calibration values should be higher by a factor of ...->threshold percent?
EDIT: in case it helps, calibration values for the chip right here are
0x10 0x23 0x3c 0x55 0x6e for currents of
1.3 2.6 3.9 5.2 6.5 Amps

Show LessHi,
I'm working on a design that leverages the BCR Power Delivery Controller in conjunction with an HX3 USB 3.0 Hub but I haven't seen enough design examples to prove that this combination of ICs works in practice.
Please see the attached block diagram and at your earliest convenience let me know if this design is headed in the right direction with regards to Power Delivery and USB 3.0.
Thank you.
