Re: [U-Boot] [PATCH 2/4] usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout value

Hello Lukasz,

It is necessary to deter the host from sending subsequent DFU_GETSTATUS request in the case of e.g. writing the buffer to medium.

Here the timeout is increased when we fill up the whole buffer. This delay allows eMMC memory to perform its internal operations. Otherwise we end up with HOST's error regarding GET_STATUS receive timeout.

Tested on the dxr2 board. "dfu -l" "dfu -U" and "dfu -D" worked.
