Hi all,
i've been working on usb tech on xmc4500 board.
i downloaded example code from dave tool.
in that code i want to implement multiple packet transfer mechanism.
i;ve theoritical idea on this mechanism but dont know how to implement it practically.

from downloaded code, endpoint maxpacketsize is 64bytes.and allocating memory for those endpoints dynamically.
do i need to change the endpoint size to 512 (not in descriptors)if i want to send that much of bytes.
could anyone help me.i;ve been beating my head since 2days about this concept.

Wrong forum? XMC4500 is from Infineon, not from NXP...

As Capiman has already stated, the product you are using is from Infineon, and should be directed to them.

Best regards
Paul
