[U-Boot] dfu download issue with ci_udc
Hi,
I am trying to download the file from dfu-utilities(version 0.7) and using the ci_udc at device side. After all the data was sent from the host, the dfu utilities sent the zpl packet but at the device side the dfu_write is not getting invoked for zero packet length and hence causing the data not to be copied to actual interface(ram/mmc/nand). I pasted here the debug log for the zpl for reference.
*handle setup CLEAR_FEATURE, 21, 1 index 0 value 3 length 0* *handle_setup: Set ep0 to OUT for Data Stage* *handle_setup: 0 length: flip ep0 dir for Status Stage* *flip_ep0_direction: Flipping ep0 to IN* *non-core control req21.01 v0003 i0000 l0* *w_value: 0x3 len: 0x0* *req_type: 0x20 ctrl->bRequest: 0x1 f_dfu->dfu_state: 0x5* *ept0 in pre-queue req 3f5284a8, buffer 3f528580* *ept0 in queue len 0, req 3f5284a8, buffer 3f528580* *ept0 in req 3f5284a8, complete 0*
My question here is does any one has tested the dfu download using ci_udc and what could be reason for this behavior?

What is your exact U-Boot verosion (git commit ID), and which exact board are you testing on?

Hi Wolfgang,
I am using mainline 2014.1 git version but integrated that with the latest ci_udc driver changes and trying to test it on zynq board.I integrated the latest ci_udc as it has fixes related to the dfu. Previously with 2014.1 its not working at all and timing out at host while trying to download so i integrated with latest driver then download was sucessfull at host side but at device side its not copying dfu buf to actual interface(its ram address in my case).This is because the zpl at the end of the dfu download not working as expected.

Hi,
I did the following modification in ci_udc driver for handling the DFU Dwonalod request with zpl and it worked for me and i am not sure whether it would be the real fix for it(that 0x21 is DFU download request with zero packet length), just sent for reference.
diff --git a/drivers/usb/gadget/ci_udc.c b/drivers/usb/gadget/ci_udc.c index 4cd19c3..64a6662 100644 --- a/drivers/usb/gadget/ci_udc.c +++ b/drivers/usb/gadget/ci_udc.c @@ -581,7 +581,10 @@ static void handle_setup(void) /* 0 length -> no Data Stage.
