In user manual, what's mean of Address phase and data phase? where is it explained?

Hi,

I have a project as below:

- CYPD3174 work in no feeback mode.

- MCU read PD contract negotiation from CYPD3174 and set voltage to ACT4751.

1. To disable opto feedback mode, i comment code in condition #if (VBUS_CTRL_TYPE_P1 == VBUS_CTRL_OPTO_FB) as below: 

PDSS_TRIMS->trim_ea1_0 = 0xA0;
/* Use internal current for reference in case of opto feedback. */
pd->ea_ctrl = ((pd->ea_ctrl & ~PDSS_EA_CTRL_IREF_BG_SEL_MASK) |
(1u << PDSS_EA_CTRL_IREF_BG_SEL_POS));

/* Enable shunt */
pd->ea_ctrl |= PDSS_EA_CTRL_EN_SHNT;

Is this the right way to disable feedback mode on CYPD3174, if not please guide me.

2. I added I2C slave (SCB0) but it unable to communicate to MCU until i comment dpm_task(port); in main function.

Please help me add I2C (SCB0) and disable feedback mode of CYPD3174.

 

Thanks and Best regards.

Hello, everyone,

We met with a problem about the connection between the chip and DAS. The chip we use is XC2224L, VQFN package. DAP connector of DAP miniwiggler. The schematic refers to the Easy Kit XC2XXX. The DAS can not recognize the chip. Memtool 4.4 was also tested but failed.

Already connect 'TDO_A' to 470R then GND and '/TRST' to 2.74K to +5V.

While connecting, 'RESET' is high. '/PORST' is high.

Do you have any idea about that?

Thanks. Show Less

Since AMD Flash memory spun off to Spansion and then to Cypress who is part of Infineon I am coming here with a question about how production locations stamped their country on AMD Flash Memory parts in the late 1980s. We received AMD AM9016DL/BFC parts which were supplied by Arrow Electronics back in 1986. Being Arrow only supplies parts received directly from OEMs I expect that the parts are authentic AMD parts. The marking on the bottom of each part is MALAYSIA. This marking located on the bottom is stamped in white ink and is in a slightly different position on each part. Looks like they may be hand stamped, possibly after testing or something. Was this normal for parts produced in 1980s?

Hi,

I have a project with PSOC 6, recently I did a merge from my teammate and i start to get this error during compilation, I am not able to fix the same please help me solve the same.  

Failed while attempting to update project 'QBL_PSOC': Could not find a part of the path 'C:\Sandbox\QBL\bitbucket\qbl_v3_firmware\QBL_PSOC.cydsn\Generated_Source\PSoC6\pdl\cmsis\include\arm_common_tables.h'..

I am aware that the generated code in the above path does not have the cmsis but I am not sure why the code is not generated even when I chose the option Build->Generate Application.  

Best Regards,

Suman

Hi, I would like to confirm if every cypress PD Device CYPD6227-96BZXI programmed with basic firmware when the part is shipped out from cypress factory. What are the basic functions of this firmware?

Hi, I'm Jay.

The question below has ended, so I'm posting the question again like this.

https://community.infineon.com/t5/USB-Superspeed-Peripherals/UART-output-message-pending-problem/m-p/324177#M28797

 

1. As the message is not working with the default SDK provided firmware also, could you tell me how the uart is connected to the PC?

- I use to connect USB 3.0 cable or USB2.0.
- As shown in the picture below, connect it directly to the PC.

- There is using 32bit set mode, but It occurred same problem from 16bit set mode.

 

2. Could you try using different cables and check if the issue is seen there also?

- There are same problems from USB 2.0 cable and usb 3.0 cable. It receive the same broken data to connect from various cables.

3. Could you also try using different PC and see if the issue persists.

- I used to another PC's, then It occurred same situations(received broken data).

4. Check the last point in the given KBA : https://community.infineon.com/t5/Knowledge-Base-Articles/FX3-CyU3PDebugPrint-Not-Printing-UART-Debu.... Also compare your schematics with AN70707 schematic checklist.

- This check list are usb setup configurations setup from 16bit or 32bit. and My test board operates normally.
- But Broken data continues to enter intermittently, causing problems.

- Please advise if this problem can occur in software or hardware regarding data breakage.

We've tried so many software attempts, and we can't find a clear answer to this intermittent data breaking problems.
Please help me as much as possible.

I wonder if Cypress can confirm that there is no software problem.
If you are confident that there is no SW problem, it will be a hardware problem and redesign the hardware.

 

Thank you.

Hi, Sir/Ms.,

Hardware: CYW20706 + UART_HCI_Interface + SPI Flash

The application code: xxx.hex

Now I want to download my application code into SPI Flash. Can you tell me what tools I need, including the software and programmer.

Thanks.
