I create a new project, but the uart is no output, i have set useUart = CyTrue, and useSpi = CyFalse, but still no uart log, is there something wrong about it?

    io_cfg.isDQ32Bit = CyFalse;

    io_cfg.useUart   = CyTrue;

    io_cfg.useI2C    = CyTrue;

    io_cfg.useI2S    = CyFalse;

    io_cfg.useSpi    = CyFalse;

CX3的UART使用很简单,只要有相应的UART初始化和配置,就可以从接口打印出需要的debug信息。这个不需要创建DMA通道。

你现在遇到的问题,原因应该很简单。我这边没有打开看你附的工程,以Cypress网站上提供的AN75779的example 为例,UARTblock 的功能是肯定没有问题的,至于你说的把这个工程烧录到CX3板子上的操作,我并没有实验过。但是你要知道这样做引入了其他因素。

总的来说,你需要确认:

1. 你的测试环境下,固件到底有没有正确run起来?

2. 你的测试环境下,没有看到UART log信息是不是你的测试有误?

3. 你的测试环境下,是不是固件运行都成功了,没有fail,所以没有打印log信息。

问题本身应该很简单,建议你不要搞的这么杂。

Hello Michael,

-are you using UART Configuration. If yes, please set to UART Configuration only and remaining configurations are disabled.

Hi, Anil,

I still can't reply on the website, it is always loading, like this. I didn't use the UART Configuration, can you tell me how to use it?

     串口需要配置的,你都没配置,怎么会有输出呢?

Hello,

I have configured the UART before, like this. Is ther any problem?

static void

CyFxUVCApplnDebugInit (

void)

{

CyU3PUartConfig_t uartConfig;

CyU3PReturnStatus_t apiRetStatus;

/* Initialize the UART for printing debug messages */

apiRetStatus = CyU3PUartInit ();

if (apiRetStatus != CY_U3P_SUCCESS)

{

CyU3PDebugPrint (4, "UART initialization failed!\n");

CyFxAppErrorHandler (apiRetStatus);

}

/* Set UART Configuration */

uartConfig.baudRate = CY_U3P_UART_BAUDRATE_115200;

uartConfig.stopBit = CY_U3P_UART_ONE_STOP_BIT;

uartConfig.parity = CY_U3P_UART_NO_PARITY;

uartConfig.txEnable = CyTrue;

uartConfig.rxEnable = CyFalse;

uartConfig.flowCtrl = CyFalse;

uartConfig.isDma = CyTrue;

/* Set the UART configuration */

apiRetStatus = CyU3PUartSetConfig (&uartConfig, NULL);

if (apiRetStatus != CY_U3P_SUCCESS)

{

CyFxAppErrorHandler (apiRetStatus);

}

/* Set the UART transfer */

apiRetStatus = CyU3PUartTxSetBlockXfer (0xFFFFFFFF);

if (apiRetStatus != CY_U3P_SUCCESS)

{

CyFxAppErrorHandler (apiRetStatus);

}

/* Initialize the Debug logger module. */

apiRetStatus = CyU3PDebugInit (CY_U3P_LPP_SOCKET_UART_CONS, 8);

if (apiRetStatus != CY_U3P_SUCCESS)

{

CyFxAppErrorHandler (apiRetStatus);

}

/* Disable log message headers. */

CyU3PDebugPreamble (CyFalse);

}

Hi,

Your UART set configurations are fine.

Please you can modify  io_cfg.useI2C    = CyFalse.

Regards,

Anil Srinivas.

Hi,

Modify io_cfg.useI2C = CyFalse, it is still no output of the UART.

I wonder that should i configure the GPIO pin of UART manually? Or it is used the default configuration.

     不仅仅是串口配置,因为你串口用的DMA模式,因此还需要DMA通道配置,如果你是想用debug模式配置串口的话,建议看一下AN75779给的例程。

你好,

我看AN75779也是没有串口log输出的,MDA配置如下。

/* Create a DMA Manual channel for sending the video data to the USB host. */

dmaMultiConfig.size = CY_FX_UVC_STREAM_BUF_SIZE;

dmaMultiConfig.count = CY_FX_UVC_STREAM_BUF_COUNT;

dmaMultiConfig.validSckCount = 2;

dmaMultiConfig.prodSckId = (CyU3PDmaSocketId_t)CY_U3P_PIB_SOCKET_0;

dmaMultiConfig.prodSckId = (CyU3PDmaSocketId_t)CY_U3P_PIB_SOCKET_1;

dmaMultiConfig.consSckId = (CyU3PDmaSocketId_t)(CY_U3P_UIB_SOCKET_CONS_0 | CY_FX_EP_VIDEO_CONS_SOCKET);

dmaMultiConfig.prodAvailCount = 0;

dmaMultiConfig.prodHeader = 12; /* 12 byte UVC header to be added. */

dmaMultiConfig.prodFooter = 4; /* 4 byte footer to compensate for the 12 byte header. */

dmaMultiConfig.consHeader = 0;

dmaMultiConfig.dmaMode = CY_U3P_DMA_MODE_BYTE;

dmaMultiConfig.notification = CY_U3P_DMA_CB_PROD_EVENT | CY_U3P_DMA_CB_CONS_EVENT;

dmaMultiConfig.cb = CyFxUvcApplnDmaCallback;

apiRetStatus = CyU3PDmaMultiChannelCreate (&glChHandleUVCStream, CY_U3P_DMA_TYPE_MANUAL_MANY_TO_ONE,

&dmaMultiConfig);

I don't know what project you created. The example of how to use UART port locate at the install path of SDK(almost every example project).

UART port in AN75779 could work normally.

Hi, anni

Attachment is my local AN75779 source code, it is certain no uart log, is it same to yours?

I test it base on CX3 board, is there anythig to configure?

Hi,

I have also same firmware.

Please refer to section 4.4 of EzUsbSuite_UG.pdf  "C:\Program Files (x86)\Cypress\EZ-USB FX3 SDK\1.3\doc\firmware"

AN75779是FX3的UVC工程,你拿这个工程烧录到CX3板子上本身就是错误的。

我看文档里说基本是一样的,另外我对比了下两个uart、dma配置也都一样。
