Dear ifx teams: 1、usb的并口控制信号，就是USB_PHY_CTL【0-12】组内等长，误差±5mil；usb的并口数据，就是USB_PHY_DQ【0-31】组内等长，误差±5mil，这个等长合理吗？ 2、USB_PHY_CLK和数据线等长还是和控制线等长？ 3.并口的阻抗需要控制吗 --- AN70707 page 14 ，讲的不是很清楚，谢谢指导！ Show Less

Hello,

I am starting work with FX3 chipset, and follow appnote AP75705 example USB Bulk Loop Auto.

I have compile the code; Program the board  via "Control center", I am having problem when trying to perform BULK transfer,

once I hit button "Transfer data Out" I am getting error 997:

BULK OUT transfer
BULK OUT transfer failed with Error Code:997

I have search support  forums and find two similar topics:

https://community.infineon.com/t5/USB-superspeed-peripherals/BULK-OUT-transfer-failed-with-Error-Code-997-while-transfering-file-above-4MB/td-p/94626

https://community.infineon.com/t5/USB-superspeed-peripherals/BULK-IN-transfer-failed-with-Error-Code-997/td-p/58096

I have tried to update driver on PC, didnt help.

I wasnt clear about how to change "endpoint timeout" at control center application, suggested in one of the postings above.

Also, if there is anything else what can be done to get the application up running, please advise at your earliest convenience.

 

Regards,

Hello,

I'm debuging the USB MSC on the CYUSB3014 board, I check the demo code(USBMassStorageDemo), it define the buffer on the ram, I want to write all data into spi flash,  so I change the buffer to 32KB, and modify the CY_FX_MSC_CARD_CAPACITY  to 4*1024*1024, and handle the write and read operations as below, spilt the data into many slice of 4096, but it doesn't work, I attach the code, can you give some suggestions, thanks a lot.

case CY_FX_MSC_SCSI_READ_10:
{
startAddr = (((uint32_t)glMscCbwBuffer[17] << 24) | ((uint32_t)glMscCbwBuffer[18] << 16) |

numBlks = (((uint16_t)glMscCbwBuffer[22] << 😎 | ((uint16_t)glMscCbwBuffer[23]));

if (!CyFxMscApplnCheckCbwParams (lun, CyTrue, CyTrue, CyTrue, (numBlks * glLunBlkSize),
&dataLength))
break;
