How to modify the size of usb msc write data

[xunwan]

RT685 USB_DeviceMscCallback kUSB_DeviceMscEventWriteResponse, I print the lba->size the value, found that the maximum is 4096。Can the value be changed? Thank you

Normally, you don't need to change this value.

Thank you for your reply. The purpose of changing this is to increase the amount of data written to eMMC each time and reduce the repeated call to eMMC write function, which can accelerate the speed of USB file transfer, but it is not sure whether it is feasible, maybe each packet of USB data can only be 512B
