Hi,
Is there any example for multiple thread in GPIF for sending continuous data from USB to GPIF to help me on my project , just like "reversing" the configuration in AN75779?
data is lost every 16KB in my project. Based on AN75779 documents, I should do multi threding in GPIF. In AN75779, data goes from GPIF to USB, but I have problem from USB to GPIF.
Thanks

Hello,
In the firmware you shared in this thread Multiple Thread in GPIF II for DR_data , i found that the configuration for serial out is 0x00001F83, /* CY_U3P_PIB_GPIF_SERIAL_OUT_CONFIG */
which is socket zero ( as mentioned in GPIF_SEROUT_THREAD_NUMBER_MASK (bit 3:2) is configured for data sink (from USB to GPIF).
As you are using two sockets (thread) in you firmware, this field should be 0. So that the socket is chosen internally (as per the thread)
So the configuration should be 0x00001F81, /* CY_U3P_PIB_GPIF_SERIAL_OUT_CONFIG */
I have tested this at my end. Refer to the results
PS: I have changed the DMA buffer size and endpoint size to 1024 (for testing purpose)
