I have problem converting AN75779 UVC example to interface with FPGA at 32bit.

How to modify firmware on AN75779 basis

Hi,

I am developing a product with Fx3s. And would like to use the GPIF II interface to interact with an FPGA.

As the first step, I used two Fx3s and one acted as the master and the other as the slave.

My question is: how to compute the number of clocks needed to read from and write to the slave side?

The following experiment were done with the default source code of AN87216 with the only change to modify the data bus width from 32 to 16.

1. Fx3 master read from fx3 slave (8bytes sent from slave out endpoint in control center)

RD_ signal last for 8 clock cycles (I think it should be 4 if bus bit width is 16 ???)

2. Fx3 master write to fx3 slave (8bytes sent from master out endpoint in control center)

WR_ signal last for 6 clock cycles (I think it should be 4 if bus bit width is 16 ???)

Hi, I have an AR0233 streaming 1920x1080p60 in RAW12 format.

I can see the MIPI receiver is capturing data, but the frame size is inconsistent, and there're no data coming through UVC to host.

I've tested with different PHY time delay (0x0A ~ 0x0F), the receiving frame size is not consistent for these tests as well.

The Frm_Sz should be 1920 * 1080 * 12 / 8 = 3110400 B

Question 2: How to configure external FLASH for FX3/CX3 (CYUSB3065)           

I use (CYUSB3065) here, and then hang an 8MB FLASH outside the chip. At present, it's no problem to start the burning, but when I modify the space configuration, it can't be realized and it can't start when burning in.           

The content of the revision includes two aspects:           

1. Compiled configuration files: C: Program Files (x86) Cypress EZ-USB FX3 SDK 1.3 firmware/common/fx3.ld           

Before amendment, it read as follows:           

I-TCM: ORIGIN = 0x100 LENGTH = 0x3F00            SYS_MEM: ORIGIN = 0x40003000 LENGTH = 0x2D000            DATA: ORIGIN = 0x40030000 LENGTH = 0x8000           

Amended as follows:           

I-TCM: ORIGIN = 0x100 LENGTH = 0x3F00            SYS_MEM: ORIGIN = 0x40003000 LENGTH = 0x2E000            DATA: ORIGIN = 0x40031000 LENGTH = 0x8000           

2. cyxtx.c           

Before modification:  define CY_U3P_MEM_HEAP_BASE ((uint8_t*) 0x40038000)           

After modification:  define CY_U3P_MEM_HEAP_BASE ((uint8_t*) 0x40039000)           

Excuse me: How can we use external FLASH to store code so that the size of code is not limited by space?

Hi,

I'm going through this document:

AN65974 Designing with the EZ-USB® FX3 Slave FIFO Interface.pdf

It mentions that you have to enable statements on pages 43-44...like:

"The DMA channels previously mentioned are set up if the following define is enabled in the cyfxslfifosync.h file in the FX3 firmware project provided with this application note. /* set up DMA channel for stream IN/OUT transfers"

#define STREAM_IN_OUT

The file cyfxslfifosync.h  in my FIFOexamples folder does not containt these lines.

What is going on?

I'm on SDK 1.3

thanks

Hi technical support team,

I'm developing cx3 firmware in-application upgrade function.But now blocked by one issue. Please help me to figure it out.

Please find my operation steps as below:

  step 1 runs good.

Set Pmode Pin to run ROMboot. It runs usbboot and ControlCenter recognized it as bootloader. And I update the 2-stage bootloader to SPI FLASH directly.

  step 2: still fine.

Set Pmode Pin to user mode and select SPI boot options. And the 2-stage bootloader(original from V1.3.4 SDK) runs successfully, cause it has been recognized as USBStreamer Example by the ControlCenter. It seems good till now.

   step 3: seems FAIL.

Use Control Center to download my application image to SPI flash. But after i chose my app.img, the ControlCenter shows SPI flash erase fail and upgrade blocked.

Isn't it a little strange here? From my point of view, no matter bootROM or 2-stage bootloader is used, the ControlCenter will download the bootProgrammer image to CX3's RAM through the usbboot channel. And the downloaded bootProgrammer in RAM will executes the SPI FLASH erase/write/read operations. But now, the same image achieves the different results.

Question 1: How would this happen? Is there any checksum not match when using different bootloader? How to resolve this problem?

Question 2: I found bootProgrammer .img located at the same routine with ControlCenter.exe. Is this image same with the sample FlashProg project in v1.3.4 SDK?  

BTW, I have read the FailSafe bootloader doc, and the image merge tool seems good. But what if I change the APPs' location in FLASH, does it still suitable? I haven't found the source code published. So, I have to use the 2-stage bootloader companion with ControlCenter.exe to upgrade my first APP, and then the APP upgrade the following APP...

  CyU3PMipicsiGetErrors (CyTrue, &errCnts);
  CyU3PDebugPrint ("mipi err:frmErrCnt=%x,crcErrCnt=%x,mdlErrCnt=%x,ctlErrCnt=%x,eidErrCnt=%x,recrErrCnt=%x,unrcErrCnt=%x,recSyncErrCnt=%x,unrSyncErrCnt=%x\r\n",
                errCnts.frmErrCnt,errCnts.crcErrCnt,errCnts.mdlErrCnt,errCnts.ctlErrCnt,
                errCnts.eidErrCnt,errCnts.recrErrCnt,errCnts.unrcErrCnt,errCnts.recSyncErrCnt,errCnts.unrSyncErrCnt);

the print is :

mipierr:frmErrCnt=0,crcErrCnt=0,mdlErrCnt=4003D50C,ctlErrCnt=4000794C,eidErrCnt=4000A778,recrErrCnt=0,unrcErrCnt=0,recSyncErrCnt=0,unrSyncErrCnt=0

you see some format is print error,and the print format sometimes is print ok, some times error.

How to slove it?

  I use cx3 on ARM(RK3399 Ubuntu),  the sensor is ov9282, 1280x800 @ 15fps, it always block in a minutes(about 30 minutes), there is no error, but can't get any frame data.  The log is as below. "commit_num" is added by myself, to count the times of data commit to usb endpoint. When it is block, there is no error,  and the "commit_num" also not update.

  But on PC, also Ubuntu OS, it always ok.

Is there anyone have this issue, and give me spme suggestion?

Hi everyone.

I'm using CX3 to transfer image data to Jetson Xavier board through USB port.

I'm using cyusb_bulk_transfer function and there is a problem of timeout.

When I check the packet transfer time, each packet tranfer usually takes 300 us but sometimes it takes 280000 us.

It causes severe frame drops of my system.

Is this due to CPU resources or an intrinsic problem of bulk data transfer?

Thank you in advance.
