Hi infineon team, 

I port my source code ( build using 1.3.1) to 1.3.4 SDK. Upon compiling my code, I get an error message such as SYS_MEM overflowed by 37624 bytes. For this issue, I have modified the fx.ld and cyfxtx.c files. Due to this modification, I need to reduce the UVC_STREAM_BUFF size (previously we used 36KB). But if i reduced the UVC_STREAM_BUFF size, i am facing GET_BUFF_FAILED issue as mentioned in this community link.

As all of our products use 36KB as the standard UVC_STREAM_BUFF size. Currently we are unable to port our code to 1.3.4 SDK.

Our expectation for SDK 1.3.5 is to have some lesser library size. So that I can maintain 36 KB as UVC_STREAM_BUFF size when I port from SDK 1.3.1 to SDK 1.3.5. Please comment on this.

Hi infineon team,

I am getting CyU3PDmaMultiChannelGetBuffer Failed with Timeout error code frequently when streaming 1080P resolution in YUV2 format. eventhough im resetting the DMA and streaming was not stopped due to this issue, but i need to stop this CyU3PDmaMultiChannelGetBuffer Failed issue because it was not observed in other resolutions. kindly help me to resolve this issue.   

SDK -1.3.4

streaming -  1080P@60FPS

CYUSB3014 意外中断传输后不重启设备不刷新USB连接如何恢复传输？

We have such a requirement: When CYUSB3014 is transmitting data in SuperSpeed mode, the USB is disconnected (for example, the USB cable is unplugged and the power supply is not interrupted), and then the USB is restored. The customer hopes that CYUSB3014 can recover the data transmission without causing the Windows Device Manager to refresh the device. It is not required to recover the data that failed to be transmitted, but only that the new data can be successfully transmitted after the USB connection is restored. Now we only know the method of calling CyU3PDeviceReset method to recover the transmission. This method causes the Windows Device Manager to refresh, which does not meet the customer's requirements. Ask for directions. Thank you.

我们有这样的一个需求：CYUSB3014正在SuperSpeed模式下高速传输数据时USB断开连接（比如拔插USB线，供电未中断），随后USB恢复连接。客户希望CYUSB3014能够在不造成Windows设备管理器刷新设备的情况下恢复数据传输，不要求恢复传输失败的数据，只要求USB恢复连接后新的数据能够成功传输。我们现在只知道调用CyU3PDeviceReset方法恢复传输的方法，此方法造成Windows设备管理器刷新，不符合客户需求。请求指点。谢谢。

Hello,

I am trying to use DMA to communicate with ASCLIN_LIN. I have met some difficulties and need help.

Failed to receive or send LIN data, and failed to enter the interrupt function

Can you help me see what's wrong with the program

Good morning, I am currently working on the development of a product which includes CY62157EV30LL-45ZXA SRAM.

We are using the device in 8-bit data mode, using address pins A0-A19, with BHE and BLE tied high, and BYTE tied low.
In many areas of the datasheet, it is specified that '29. During this period, the I/Os are in output state. Do not apply input signals.'

We understand this that if the I/Os are in an output state, and we drive a voltage into these pins at this time - it is possible that we may physically damage the memory. We are not comfortable shipping a product that could be damaged by firmware - validated firmware or not.

Are we understanding this correctly? And in such a case, would Infineon recommend the use of series resistors on the data lines to stay within the 20mA 'output current into outputs (LOW)' specification, within the maximum ratings section of the datasheet?

Many thanks in advance

I copied the code from the midi_server example over to a new MTW project and I can send Midi notes to iOS apps (Garageband, MidiWrench). However the server does not seem to receive any Midi events from the phone. I added LEGATTDB_CHAR_PROP_WRITE_NO_RESPONSE to the GATT db in the HANDLE_HSENS_SERVICE_CHAR_NOTIFY characteristic entry, and now the iOS apps do see that the device is capable of Input as well as Output.

I expected that when the client sends a Midi note or CC that the callback I registered (midi_server_gatts_callback) would get called but that does not seem to happen. Am I missing some obvious step?

Unfortunately, the MTW documentation is pretty light on tutorials and overviews 😞

Thanks, Norm

Hello 

I'm looking for a transistor to be used for RF amplification, at the single frequency of 2GHz.

The requirements are ~15dB gain, and 15-18 OP1dB. 

my preference is to use high Vce (up to 10V) and lower current (15mA max) 

Can you please recommend on a part? 

Thanks

I was using n channel power mosfet 

AUIRFP4110.

by applying Vgs=12 V (in series  with 1k resistor) , Parallel resistance between GS was 1K(for fast switching), Vds=50 V .

Mosfet was working fine till 5 Amp load & switching was too good but when I switched the load to 10 Amp ; the mosfet got blown up immediately. Testing scenario was within the specified range as per datasheet ; please let me know your valuable thoughts to rectify this problem.

Regards,

Hi,

I am using CCG3PA board in my device to work  as PD source and QC source.

It was working as PD source fine but it is not working as QC source when i connect it to QC sink.

How can i switch ccg3pa from PD to QC mode?

All QC related flags are set in my code BATTERY_CHARGING_ENABLE and below  provided with my EZ-PD configuration utility screenshot. 

When i connected a sniffer between My device and sink it is sending Source capabilities for some time and then vbus is droping to zero when there is no response from sink.

Is there any Flags i am missing to enable ? can you suggest procedure to switch between PD source mode to QC source mode?

Thankyou.
