I want to a systick API or GetTickCount API to make some applications in the CCGX platform,  the systick should be able to calculate the time of 1ms, can you tell me the API?

Hi,

In my design, I have CCG4 Device (CYPD4126).

I want to program the CCG4device using the Miniprog3 SWD interface (1V8) 5pin connector, Below is the reference connection I have done between my CCG4 device and Miniprog3.

After connection, I want to program through the PSoC programmer.

I selected Programming mode: Reset

Connector type: 5P,

Interface: SWD,

Voltage Level:1.8V and Clock speed: 1.5MHz

with these parameters I am unable to program the device. "The error is showing is PSoC device is not acquired, check connection between the chip and programmer". and warning is Device is not powered, apply power to the target board to be in reset mode, but my CCG4 is already powered on,

But with the same settings I Changed only programmed mode to Power cycle MODE then Iam able to program the device and I got the message saying Program is successful. But Output was not coming.

As of I know the difference between Reset Mode and Power cycle mode is as below image.

Can anyone clearly explain What is Reset Mode and Power cycle mode. What will be the impact of these modes?

Hi. Infineon

when I build the newly EZ-PD configuration utility software, the ver. is 1.4.0, build:261. to support the CMG2 CYPD2803 programming in factory, it is ok in the MTK(manufacturing test kit) .  when I need program the CYPD2703 in the MTK with this ver. 1.4.0 build:261, it appears busying forever when the ic is passing, holding(busying) at once,without any time to let us take down the programmed IC and plug in new IC as below pic.

when I use former ver. like 1.3.9,it may support CYPD2703, but it can't support CMG2 CYPD2803.

pls help to feedback 1.4.0 build:261 software issue, and when you may release newly firmware to support both CMG1 and CMG2 programming in MTK .

thanks

Hi,

Does PSoC creator (or any other development environment) support firmware development for this specific device? Closest I can find is CYPD2122 that has firmware templates available. If I would retarget that to CYPD2119 I would still need the bootloader image for CYPD2119 and I've not found that.

Hey there,

I'm new to programming microcontrollers, so please bear with me when I ask these questions.

I'm programming the CYPD3171 included on the CY4532 EVK and looking through a code example compatible with the kit. The code example is CYPD3171-24LQXQ_cla01.cydsn for reference. 

I'm having a hard time understanding the kit's guide and the code example's architecture, but is there a way to update the firmware to alter the power output of the USB-C port, or is the power output completely dependent on the device interfaced with said port? I'm using the EVK as a means to test code for another PCB I'm designing for PD applications that uses another CCG3PA chip, but I need to work out the logic involving changing the voltage on the USB-C VBUS line first.

Again, I'm very new to this environment, so please be patient with me in my struggles. I appreciate any feedback or help. 

Hello

Please tell me about the DC characteristics of the I/O of CYPD3171.Please check Table 8 I/O DC specifications.

Q1) Could you please tell me the values of VOH and VOL when VDDD=3.3V?

Q2) In relation to Q1) above, please share a document (ex. characteristic chart) that shows how much the Output Voltage changes depending on the IOH and IOL values.

Best Regards

Hello

Regarding programming FW by SWD with Miniprog3, is it possible to connect two ICs (CCG3PA) in parallel and program different firmware (FW-A = CCG3PA ①, FW-B = CCG3PA ②) to each IC as shown in the attached figure?

Best Regards
