USB20 Host Controller doesnt send ACK after BULK IN received

Post by meir »

I am testing the integration of a USB 2.0 host controller IP connected to a PHY in a chip system
I am sending a BULK IN transfer to a device emulator by writing the expropriate qTD
I am requesting 512 Bytes (max pkt size according to High Speed protocol).
I am receiving DATA0 size 512 but the Host Controller does not send an ACK
Any ideas how to debug this issue ? What might be the cause of this problem ? (register configs, transaction configurations )
