USB Low-Full-High Speed Peripherals

Hello
 CX3 JLINK DEBUGGING.Every time I click resume while debugging, the program starts debugging, but it doesn't stop when it hits a breakpoint. Another problem is that I click step over CyU3PKernelEntry () and the program keeps running for more than half an hour without stopping, I want to know what causes this, every time I debug the program I can't stop, no result. I hope you can help me to answer this question, thank you very much!

Our product based on cy7c68013a.

Most of them are Normally operating well. But some product did not be recognized about 2~3 times out of 10.

Power source, reset timing, i2c clk, data lines were good. However,there was someting very strange about i2c data voltage abnormal.

There was no pull up, or data transaction, but voltage level about 1.4v with pull down sometimes.(our voltage level 3.3v)

I haven't seen this symptom. Would you tell me how to debug this symptom? Wold you tell me how to solve this problem?

Hello
I am now debugging my uvc project and the first step is to make sure if my sensor is configured correctly, so where can I get the configuration data of the sensor's register while debugging and how do I need to set the debug information?
Please help me, thank you very much!

I want to get more information about the CY7C68023 controller:

1. Is  CY7C68023 compliant with any ONFI/Toggle protocol for NAND? 
2. What timing parameters do the 30/50/100ns "NAND flash timing" refer to?
3. Does the software include the ability to:
       write/read specific data to/from a specific memory location? (e.g. write 0x123456789 to address 0x30FF) so that I will be able to control every data transaction to the NAND?
4. Where can I buy the "CY3685 EZ-USB NX2LP" board from? (if there is no stock on digikey)

Would like to get as much information about this development board.

Thank you.

Hi

We have been performing some tests under Linux with the CY7C65215A running in i2c master mode.

When no receiver is present with the transmitted address or the receiving device is busy and unable to respond so a NACK occurs that the CY7C65215A appears to be holding the SCL line low until a USB timeout occurs.

Would you please advise how to overcome this issue?  We are running under Linux.

Thanks

Hi

Would you please advise if there is a Linux solution for the CY7C65215A Errata 5 - I2C Reads are slower when USB-Serial is configured as I2C Master?

The workaround provided lists a windows solution only.

Hi

I have a question about the ATA standards supported by theI have a question about CY7C68300C-56LTXC

Qestion1
I use the IF below. Is there a compatibility issue?
・ ATA3
-ATAPI command: Compliant with SFF-8020 Rev2.6 and SFF-8090 Rev0.99 specifications
・ Transfer mode:
PIO mode 0,1,2,3,4
Single Word mode 0,1,2
Multi Word mode 0,1,2

I checked the data sheet, but some modes are not supported.
Should we determine in the system that an unsupported mode is needed?

Qestion2
CY7C68300C-56LTXC The following signals are not supported.
・ DASP
・ PDIAG
・ CSEL

Does CY7C68300C-56LTXC support only one ATA device?
Is the above signal unnecessary if there is only one ATA device?

Hi

Does the CY7C65215A Linux API provide a method for i2c stuck bus recovery?  i.e. if a device connected to the master is holding the SDA line low can the CY7C65215A clock out the slave device so that it releases SDA?

Thanks

What is the power consumption of the FX2LP18  when held in reset for both the three different supply inputs? I am working on a very power sensitive design and the USB will only be needed when powered externally. When in battery mode, I want to minimize the power consumption as much as possible by holding the part in reset (or even adding a power switch if necessary). The datasheet shows Isusp current, but it is not clear which power rail that is referring to. Also, it's not necessarily the same as when the part is in reset.
