USB low-full-high speed peripherals Forum Discussions
Hi
This is some weird situation.
When i receive data from fx2lp, i use windows pc application made by myself. (as is pc)
That made c++ and i use xferdata().
The weird phenomenon is your USBlyser have to always run.
Because my pc application does not receive data from fx2lp without USBlyser run.
Does have any experiance this situation? I don't know what are USBlyser doing. But if i want to receive the data from fx2lp, i have to turn on the USBlyser.

Hi
I have some query about synchronous and asynchronous mode of fx2lp in slavefifo mode.
Actually, i don't know what which one mode is good for some situration.
Could you explaine me more?
Show LessI'm using Cypress's fx2LP slave fifo mode with fpga.
I have send data to fx2lp from fpga , then i check received data.
I have configured firmware 512*4 for fx2lp.
But here's problems.
When i have received the number of 2048 data, then 1 data missing.
Like the following.
0 1 2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255
1 2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255 0
2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255 0 1 2 3 4 ..255 0 1
...
I don't know why this happen?
Also how can i handle of this problem?
Hi,
I wanto to test bolkloop firmware on Linux platform, but firmware is loaded to EZ USB on Windows 7 64b platform via CyConsole.
But I think, that firmware is not loaded correct to ezusb.
I attach the file, where you see screen shots of my driver, .inf file, CyConsole.
After downloading firmware the ez-usb is disconnected from PC, and when I push reset button on board with ezusb, dhe device is connected.
For testing I use this application, which use libusb library (http://www.cypress.com/?docID=35633). I cen read informaton about the device, but bulkloop transfer dont work :
"This function is for testing the bulk transfer. It will write on OUT endpoint and read from IN endpoint.
For seeing whole bulkloop action from HOST -> TARGET -> HOST, Please run correct firmware on TARGET and restart this program"
Show Lesshello, i am trying to build the example firmware(FX2 to extsync FIFO) that came with application note AN66806,i opened the 'uv2 file in keil software and tried to compile but it says "user command terminated:exit code 4".
i want to change the gpif waveform of that example so that i can burn new hex code to cy7c68.
Thanks.
