* usb: gadget: f_dfu: Add get_alt function to pass the USB compliance testStefan Roese2015-01-18-0/+8
| | | | | | | | | | | | | | | | | | | | Without this function the USB compliance test (USB 2.0 Command Verifier) will fail in the "Interface Descriptor Test" with this error message: FAIL (1.2.51) A successful GetInterface request must return the alternate setting set by a prior call to SetInterface. Lets add this function to read back the value so that the DFU device fully passes the USB compliance test.

* dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski2014-09-02-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | This commit provides distinction between DFU device detach and reset. The -R behavior is preserved with proper handling of the dfu-util's -e switch, which detach the DFU device. By running dfu-util -e; one can force device to finish the execution of dfu command on target and execute some other scripted commands. Moreover, some naming has been changed - the dfu_reset() method now is known as dfu_detach(). New name better reflects the purpose of the code. It was also necessary to increase the number of usb_gadget_handle_interrupts() calls since we also must wait for detection of the USB reset event. Example usage: 1. -e (detach) switch dfu-util -a0 -D file1.bin;dfu-util -a3 -D uImage;dfu-util -e access to u-boot prompt. 2. -R (reset) switch dfu-util -a0 -D file1.bin;dfu-util -R -a3 -D uImage target board reset Signed-off-by: Lukasz Majewski <l.majewski@samsung.com> Reviewed-by: Stephen Warren <swarren@nvidia.com> Tested-by: Stephen Warren <swarren@nvidia.com>
* dfu: add write error handlingStephen Warren2014-08-09-4/+16
| | | | | | | | | | | | | | | | | | | | | | | | | | Fix calls to dfu_write() and dfu_flush() to detect errors in the I/O itself. This could happen due to problems with the storage medium, or simply when trying to write a FAT/ext file that is larger than the buffer dfu_mmc.c maintains for this purpose. Signal the error by switching the DFU state/status. This will be picked up by the DFU client when it sends the next DFU request. Note that errors can't simply be returned from e.g. dnload_request_complete(), since that function has no way to pass errors back to the DFU client; a call to dnload_request_complete() simply means that a USB OUT completed. This error state/status needs to be cleared when the next DFU client connects. While there is a DFU_CLRSTATUS request, no DFU client seems to send this. Hence, clear this when selecting the USB alternate setting on the USB interface. Finally, dfu.c relies on a call to dfu_flush() to clear up the internal state of the write transaction. Now that errors in dfu_write() are detected, dfu_flush() may no longer be called for every transaction. Separate out the cleanup code into a new function, and call it whenever dfu_write() fails, as well as from any call to dfu_flush(). Signed-off-by: Stephen Warren <swarren@nvidia.com>
* dfu, nand: add medium specific polltimeout functionHeiko Schocher2014-05-08-1/+9
| | | | | | | | | | | | | | | | | | add a possibility to add a medium specific polltimeout function. So it is possible to define different poll timeouts. Used on nand medium, for setting the DFU_MANIFEST_POLL_TIMEOUT only on nand ubi partitions, which is currently the only usecase.

* usb: dfu: introduce dfuMANIFEST stateHeiko Schocher2014-03-23-6/+42
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | on nand flash using ubi, after the download of the new image into the flash, the "rest" of the nand sectors get erased while flushing the medium. With current u-boot version dfu-util may show: Starting download: [##################################################] finished! state(7) = dfuMANIFEST, status(0) = No error condition is present unable to read DFU status as get_status is not answered while erasing sectors, if erasing needs some time. So do the following changes to prevent this: - introduce dfuManifest state According to dfu specification ( http://www.usb.org/developers/devclass_docs/usbdfu10.pdf ) section 7: "the device enters the dfuMANIFEST-SYNC state and awaits the solicitation of the status report by the host. Upon receipt of the anticipated DFU_GETSTATUS, the device enters the dfuMANIFEST state, where it completes its reprogramming operations." - when stepping into dfuManifest state, sending a PollTimeout DFU_MANIFEST_POLL_TIMEOUT in ms, to the host, so the host (dfu-util) waits the PollTimeout before sending a get_status again.

* usb: dfu: f_dfu: Provide infrastructure to adjust DFU's Poll Timeout valueLukasz Majewski2013-12-18-3/+36
| | | | | | | | | | | 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. Signed-off-by: Lukasz Majewski <l.majewski@samsung.com>
* dfu: Implementation of target reset after communication with dfu-util's -R ↵Lukasz Majewski2013-07-29-0/+2
| | | | | | | | | | | | | | switch This patch extends dfu code to support transmission with -R switch specified at dfu-util. When -R is specified, the extra USB_REQ_DFU_DETACH request is sent after successful data transmission. Then dfu resources are released and reset command is issued.

| | | | | | | | | | | | | | | This subtle change fix problem with too small amount of allocated memory to store DFU function pointers. One needs to allocate extra space for sentinel NULL pointer in this array of function pointers. With the previous code, the NULL value overwrites malloc internal data and afterwards free(f_dfu->function) crashes.

* usb, dfu gadget: switch to dfu mode in dfu_bindHeiko Schocher2013-06-30-1/+3
| | | | | | | | | | | | | | | | | | | | | | | - set in to_dfu_mode() f_dfu->dfu_state = DFU_STATE_dfuIDLE as after every to_dfu_mode call this is done, so move this into to_dfu_mode - switch in dfu_bind() into dfu mode: This fixes wrong "dfu-util -l" output, when calling "dfu-util -l" after a board reset, without doing a download before.
