Hi Cypress

We need CYUSB3035-BZXI SPI overshoot and undershoot spec for signal quality test , Can you help to get the spec for verifying , Thank !!

Hi Sir,

我在调试43455的时候，在加载FW出现error，导致DHD 加载失败。

我使用的环境是IMX.8的平台，arm64，Linux4.18，DHD版本125.15~125.19都有验证过，海华197（43438），288（43362），256（43455）EVK，其中197,288都可以正常工作，256在以上所有版本驱动都出现FW加载失败的问题，理论上来说43438与43455共用同一版驱动没有问题的，也怀疑过可能是256EVK本身的问题，用FMAC验证256EVK是可以正常工作的，所以现在比较疑惑，请帮忙分析下，谢谢。

以下是256加载驱动时的dmesg log，其中一份是通过256EVK的SD口供电，另一份是256EVK的USB口供电。

SD口供电dmesg：

Dear sir，

After power on，Why  CyU3PGpifLoad failed？ 

Log is below 

CyFx3UvcIoMatrixReInit:Cfg1 = 0x410, Cfg = 0x510
CyFx3UvcInitGpifSm: CyU3PPibInit Success
CyFx3UvcInitGpifSm: CyU3PGpifLoad failed, error code = 0x46

你好，我用Bus Hound软件（或其他工具测试遇到一样的问题）测试接收cx3 hid数据。当数据量频率不大时（数据包都是一样大小，64个字节），接收数据都正常，可以测试一天一夜。但是当发送的数据频率增大时，cx3这边很容报错：CY_U3P_USB_EVENT_EP_UNDERRUN，此错误的解释是：Indicates that a data underrun error has been detected on one of the USB endpoints. The event data will provide the endpoint number. 当高频率发送hid数据出现此错误后，即使复位hid，也无法恢复正常。复位hid如：

if (glIsHIDApplnActive)
{
CyFxUsbHidApplnStop();
}
CyFxUsbHidApplnStart();

请问如何解决cx3这种高频率发送hid报错问题？

I am testing CX3.

In high speed image, image was broken.

Right side of image is broken. 

(UVC , all registers and buffer size is same to default value. Source is made by "EZ USB Suit".

Please let me know how to fix this problem.

Hello,

As channels 12 & 13 seem to be disabled, I assume wifi chipset is configured for US.

How can I change the country under Linux?

I add country=FR in wpa-supplicant conf file without success

I try to use iw without success too

 What is Cypress recommend way to set the Country in Linux?

I am using Modus Toolbox 2.2 with the PSoC 6 WiFi-BT Pioneer Kit.  I can get the CapSense examples working on their own, but when I tried to use CapSense with the sensor-motion-bmi160 example - the CapSense initialization fails.  I suspect that it is because the CapSense is using cyhal_ezi2c and the bmi160 is using cyhal_i2c.  Is there an example of these sensors working together?

Thanks,

Ralph

We are trying to  configure parameters with GX3 EEPROM Tools on Test device driver in Win7

But it pops up the error as the following 

<Erase EEPROM>

Result : OK

<Program EEPROM>

Result : ERROR : EEPROM Program uncomplete

<Production Test : EEPROM PROGRAM>

Result : EEPROM Verity Error

The model of EERPOM which is used to save parameters is AT93C66B in PCB board but we are not sure that suffix “B” is appropriate for GX3.

I would like you to give me your tips to get through it.

Thanks and best regards,

Wonjin Han.

I am trying to communicate with hyperflash through microblaze connected with hyperbus IP. But neither read nor write operation is taking place. I have simulated it and observed Command address field out from HYperbus IP. There is difference between the Hyperflash datasheet mentioned waveform and the one observed by me during simulation. I have attached images of code, waveform from simulation and from the datasheet

Can someone please let me know what mistake is causing problem in communicating with the hyperflash?
