Hi,

I am using the following eval board and not using RTOS in my project. I am trying to setup an interrupt based systick timer and looking for some information on how to do so since I haven't setup any interrupts yet.

https://www.infineon.com/cms/en/product/evaluation-boards/eval_pmg1_b1_drp/

I try to debug the example firmware of the Super Speed Explorer Kit USBBulkSourceSinkLED on our custom PCB with a FX3S on it via JTAG. I changed the LED_GPIO define to (49) because our LED is at this pin. I Am using EZ-USB FX3 SDk V1.3.4. on a Windows 10 PC.

For debugging we tried to use the SEGGER Jlink  PLUS Compact with the ARM 14-pin Adapter and  J-Link Software and Documentation Pack v7.96b. We followed the Section 3.1 in the EZUsbSuite User Guide, but without success.

Error Message from EZ USB Suite with JLINK:

 Error in final launch sequence

Failed to execute MI command:

tbreak main

Error message from debugger back end:

Cannot access memory at address 0x40004a00

Cannot access memory at address 0x40004a00

So we build a PCB with a 14-pin JTAG Header and the schematic from the Explorer Kit with the CY7C65215-32LTXI on it to get an integrated Debugger. We configured it like the Explorer Kit using the Cypress USB-Serial Configuration Utility User Guide. We followed the Section 3.7.2 JTAG from the SuperSpeed Explorer Kit User Guide as well as 3.2. Debugging with OpenOCD Section from EZ USB Suite User Guide.

Error Message from EZ USB Suite with CY7C65215:

Error in final launch sequence

Failed to execute MI command:

continue

Error message from debugger back end:

Warning:\nCannot insert breakpoint 1.\nError accessing memory address 0x400040b0: (undocumented errno -1).\nCannot insert breakpoint 3.\nError accessing memory address 0x400040dc: (undocumented errno -1).\nCannot insert breakpoint 2.\nError accessing memory address 0x40004a00: (undocumented errno -1).\n

What does these error messages mean ?

Are there known issues with custom hardware and debugging via JTAG with the FX3S ?

Anomaly I. - Resolved; It was a USB device issue 

When testing the CY6611 Eval-kit we observed that the write speed is significantly lower when using the Type-C connector compared to the Type-A connector. Tested on DS3, DS4, DS2 and DS5 with the same result, in both orientations (Type-C). Please find the attached screenshot from CrystalDiskMark.

USB device used for testing: Kingston DataTraveler Max 256GB USB3.2 Gen2.

Anomaly II.

We also tested the Eval-kit with USB3.2 Gen1 devices. If the USB hub is USB3.2 Gen2 capable, we expect it to be able to stream two USB3.2 Gen1 devices at the same time. But the maximum speed we were able to achieve was about 3100Mbps (instead of 8520Mbps what we measured with only one USB3.2 Gen2 device).

In this case, we used our in-house cameras for testing because it is easier for us to control and measure the data transfer rate. One device connected to CY6611 was able to achieve the USB3.2 Gen1 speed but when the second device is connected, the maximum transfer speed must be limited to 3100Mbps for stable data transfer. The situation was the same for three or four devices: the total transfer speed must be set to 3100Mbps.

Is this the expected behavior for CYUSB4347? Is there any option to increase the transfer speed or it is defined by design?

If you need any more information to investigate this problem, I would be more than happy to provide it for you.

We would like to use Host SDK to support  customer to develop  Meteor Lake platform.

Customer has a question about choice of REIMER.
1). Except Intel Hayden Bridge Retimer, Do you know of any other USB4 RETIMER  can be used for intel platform ?
2). Is  SDK able to support ohter USB4 RETIMER for intel platform ?

Is there any way to automate firmware flashing for CYUSB4347-BZXC?

Our production team has to update the FW of the CYUSB4347-BZXC IC. They currently use the EZ-USB HX3PD Configuration utility for this task. However, we aim to automate this process to enhance efficiency and reliability.

We are seeking a command-line solution or a similar alternative.

We are working on a project that streams 1936x1552 RAW12 data from IMX623 imager from Sony. I was able to get an image, but only if I set the output pixel clock for the CX3 MIPI config over 100 MHz and the image does not display correctly(on Windows camera app, VLC) and after some time the stream stops and I get a CB Failure. 

I made another thread and the solution was to allocate more memory to the DMA buffers, but I wasn't able to.
I modified CY_U3P_SYS_MEM_TOP to 0x40080000 and CY_U3P_MEM_HEAP_BASE in cyfxtx.c and the fx3.ld file like here, but I still have the CB failure, do I need to change anything else? I tried increasing CX3_UVC_DATA_BUF_SIZE in cycx3_uvc.h, but I don't get an image at all after that.

I refer to someone else's project on the Internet, but after loading it in, I found that I can't find any of its header files, how should I add the path to the header files?
