Hi I am using FX3 USB superspeed hardware. I am trying to do file transfer from Master to Slave using cyusb_linux application. I have downloaded the latest application from your website. My OS is Ubuntu. I am getting the below errors LIBUSB_ERROR_TIMEOUT ,  LIBUSB_ERROR_OTHER and unable to clear halt data pipe. I want to transfer bulk files from master to slave. Kindly help me out in this. I have attached the screen shot. Thanks in advance.

Hi, My hardware is FX3 USB super Speed device with vendorId 04b4 and product Id 00f2. My OS is Ubuntu 18.04. version. I have installed Autoslave and Automaster code in hardware. I am running cyusb_linux (which i downloaded from your website ) from terminal which opens control center GUI application. I went to the tab Data Transfer and i selected master from list above. Then selected a file from data out and clicked on send button. File does not transfer and i get Libusb_timeout, libusb_other, libusb_error_IO errors. Even if the file is sent i cant receive the file in slave.

Hello,

Look like are you sending more than 16KB of data and don't have space in FX3 DMA to hold this data. so can you try like send less than 16KB files from the master and receive the same on the slave side?

You can update FW also to increase DMA size.

Hello,

I tried file transfer with file having 7 bytes, but got the the same error. I would like more information. Actually our requirement is this FX3 Super speed device should transfer 1GB of file. i do not want it to save in FX3. is it possible to transfer so from your application?? If not possible kindly suggest any other software or hardware of yours.  I have attached Test1.docx which i am trying to send and receive.

Thanks in advance

Hello Amulya,

can you share Test1.docx and not get it in your replay?

We can transfer a 1GB file with Fx3 but you need to receive data at the other end at the same time, if you fail to receive data it will fail to send also because Fx3 can buffer only data based on DMA Size, if you cross it we will  fail to send.

Hello,

    I have attached the Document. I have written another application which keeps receiving data for any GB file but the thing is it is taking 10seconds to transfer  and receive 1GB file. So i wanted to switch back to your application.  Kindly tell how to solve this.

Thanks in advance.

Hello Amulya,

I tested this file you share and we can transfer it with this tool because it is just 11KB, less than 16KB of data work without error because this is the size of DMA.

your requirements are not fulfilled with cyusb_linux tool out of the box, you need to handle the error and failures of data send and retry it. you may use cyusb_linux_1.0.5\src\06_setalternate.CPP and you need to retry data which get failed to send and replace random data with your file.

Hi tried all but speed of the file transfer is not as expected. It is taking 10 seconds to transfer 1GB of file. We have 2(Master and slave) applications and FX3 firmware i am not able to conclude which is taking more time to transfer data. Is there any way to know why the speed is low.

Hello Amulya,

If you test your setup with a streamer app then what throughput are you getting? if it does not get 350MBPS then you need to update FW.

Hello Amulya,

you need 2 PC and a test streamer app, in one PC you select master FX3 as the OP endpoint, and on another PC Slave FX3 as the input endpoint and test.

Or you can try with the attached FX3 FW ones this we tested with windows and we get 350MB/s.

Hello Amulya,

You need to update to "cyusb_linux_1.0.5\configs\cyusb.conf" file with this FW PID, please add below 2 lines in this file and save it.

04b4    F6F1        FX3 Streamer Example 1

04b4    F6F2        FX3 Streamer Example 2

And then run this 3 command 

sudo cp configs/cyusb.conf /etc/

sudo cp configs/88-cyusb.rules /etc/udev/rules.d/


sudo sh configs/cy_renumerate.sh

and reopen cyusb_linux it will show now FX3.

Hello Amulya,

I can see in the attached image both devices are connected to one PC, As I said before you need 2 PC to test the streamer app, in one PC you select master FX3 as the Output endpoint, and on another PC Slave FX3 as the input endpoint and test.

Hello,

Can you test the same setup with FX3_SDK_Linux\cyusb_linux_1.0.5\src\09_cyusb_performance app this will help to check the data transfer rate of device?
