Hi,
We use EZ-USB FX3, Source code is base the "AN65974" project.
We want to change bulk mode to isochronous, but failed. Could you help us to set it?
Thank you very much!
Attachment is the source code.
Solved! Go to Solution.

Hello,
Please let me know if this happens for the very first time when the transfer is done.
I am able to transfer 1024 bytes (as per test data) of data from the control center.
Please let me know if the device(FX3) enumerates as USB 3.0 or USB 2.0 device and are there any other devices connected to the PC with isochronous endpoints.
Regards,
Rashi

Hello,
As I didn't find the attachment in your post, I have modified the default Slave FIFO firmware (attached with AN65974) by changing the BULK endpoints to Isochronous endpoints. The MACRO "ISOC" will enable the isochronous endpoints in the firmware.
Please let me know if this helps

Hi RashiV, we tried to send data(AN65974-TEST.txt file) with the code(SLAVEFIFOISO) you have attached. The size of test file is 1024bytes. Do we need to transfer as 1024*3*16 bytes ? . Please let us know how many bytes of data to be transferred.

Thanks RashiV,
The mistake I done was I have connected USB 2.0 and checked. Now, I am able to transfer 1024 bytes (as per test data) of data from the control center.
