Hi,
according to this thread https://community.cypress.com/t5/USB-Superspeed-Peripherals/FX3-change-packet-size-in-ISOC-module-US...
i was able to change the CY_FX_ISO_MAXPKT parameter.
when Running OUT Traffic (from the EP_OUT) from the streamer GUI, i was able to see in USB3 Trace that the Data len that my host is sending is actually the one that i defined in CY_FX_ISO_MAXPKT parameter.
my problem here is when i want to test the other way, IN_EP from the streamer GUI.
when choosing the IN_EP from the Streamer GUI and press on start, im able to see that there is traffic but in the USB3 Trace i see that the Data Len that the FX3 sending is always 0 no matter what CY_FX_ISO_MAXPKT is configured.
only when CY_FX_ISO_MAXPKT = 1024 i able to see that the FX3 is success to send ISOC Data Packet with Len = 1024 (verified it in the USB3 Trace).
is there something else that i need to configure? or maybe i miss something here?
more details (from the USBIsocSourceSink module) :
/* ISO Mult settings for SS and HS operation. */
#define CY_FX_ISO_PKTS (1)
/* Burst length in packets supported by the ISO endpoints, when operating in USB 3.0 mode. */
#define CY_FX_ISO_BURST (1)
/* Dma buffer size multiplier. As ISO endpoints will only transfer ISO_PKTS * ISO_BURST packets of data in*/
/* each interval, this can be set to 1 without any performance limitation. */
#define CY_FX_DMA_MULTIPLIER (1)
