* dfu: Provide means to find difference between dfu-util -e and -RLukasz Majewski2014-09-02-1/+4
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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: allow backend to specify a maximum buffer sizeStephen Warren2014-08-09-1/+2
| | | | | | | | | | | | CONFIG_SYS_DFU_DATA_BUF_SIZE may be large to allow for FAT/ext layouts to transfer large files. However, this means that individual write operations will take a long time. Allow backends to specify a maximum buffer size, so that each write operation is limited to a smaller data block. This prevents the DFU protocol from timing out when e.g. writing to SPI flash. I would guess that NAND might benefit from setting this value too, but I can't test that. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* dfu: defer parsing of device string to IO backendStephen Warren2014-08-09-9/+13
| | | | | | | | | | | | | | Devices are not all identified by a single integer. To support this, defer the parsing of the device string to the IO backed, so that it can apply the appropriate rules. SPI devices are specified as controller:chip_select. SPI/SF support will be added soon. MMC devices can also be specified as controller[.hwpart][:partition] in many commands, although we don't support that syntax in DFU. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* dfu: fix some issues with reads/uploadsStephen Warren2014-08-09-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DFU read support appears to rely upon dfu->read_medium() updating the passed-by-reference len parameter to indicate the remaining size available for reading. dfu_read_medium_mmc() never does this, and the implementation of dfu_read_medium_nand() will only work if called just once; it hard-codes the value to the total size of the NAND device irrespective of read offset. I believe that overloading dfu->read_medium() is confusing. As such, this patch introduces a new function dfu->get_medium_size() which can be used to explicitly find out the medium size, and nothing else. dfu_read() is modified to use this function to set the initial value for dfu->r_left, rather than attempting to use the side-effects of dfu->read_medium() for this purpose. Due to this change, dfu_read() must initially set dfu->b_left to 0, since no data has been read. dfu_read_buffer_fill() must also be modified not to adjust dfu->r_left when simply copying data from dfu->i_buf_start to the upload request buffer. r_left represents the amount of data left to be read from HW. That value is not affected by the memcpy(), but only by calls to dfu->read_medium(). After this change, I can read from either a 4MB or 1.5MB chunk of a 4MB eMMC boot partion with CONFIG_SYS_DFU_DATA_BUF_SIZE==1MB. Without this change, attempting to do that would result in DFU read returning no data at all due to r_left never being set. Signed-off-by: Stephen Warren <swarren@nvidia.com>
* dfu: mmc: Provide support for eMMC boot partition accessLukasz Majewski2014-05-15-0/+3
| | | | | | | | | | | | | | Before this patch it was only possible to access the default eMMC HW partition. By partition selection I mean the access to eMMC via the ext_csd[179] register programming. It sometimes happens that it is necessary to write to other partitions. This patch adds extra attribute to "raw" sub type of the dfu_alt_info environment variable (e.g. boot-mmc.bin raw 0x0 0x200 mmcpart 1;) It saves the original boot value and restores it after storing the file.

* dfu: mmc: raw data write fixMateusz Zalega2014-05-05-5/+0
| | | | | | | | | | | | | | | | | | | | | | | | When user attempted to perform a raw write using DFU (vide dfu_fill_entity_mmc) with MMC interface not initialized before, get_mmc_blk_size() reported invalid (zero) block size - it wasn't possible to write ie. a new u-boot image. This commit fixes that by initializing MMC device before use in dfu_fill_entity_mmc(). While fixing initialization sequence, I had to change about half of dfu_fill_entity_mmc's body, so I refactored it on the way to make it, IMHO, considerably more comprehensible. Being left as dead code, get_mmc_blk_size() was removed. Tested on Samsung Goni.

* usb: dfu: introduce dfuMANIFEST stateHeiko Schocher2014-03-23-0/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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.

* dfu: ram supportAfzal Mohammed2013-09-24-0/+18
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | DFU spec mentions it as a method to upgrade firmware (software stored in writable non-volatile memory). It also says other potential uses of DFU is beyond scope of the spec. Here such a beyond the scope use is being attempted - directly pumping binary images from host via USB to RAM. This facility is a developer centric one in that it gives advantage over upgrading non-volatile memory for testing new images every time during development and/or testing. Directly putting image onto RAM would speed up upgrade process. This and convenience was the initial thoughts that led to doing this, speed improvement over MMC was only 1 second though - 6 sec on RAM as opposed to 7 sec on MMC in beagle bone, perhaps enabling cache and/or optimizing DFU framework to avoid multiple copy for ram (if worth) may help, and on other platforms and other boot media like NAND maybe improvement would be higher. And for a platform that doesn't yet have proper DFU suppport for non-volatile media's, DFU to RAM can be used. Another minor advantage would be to increase life of mmc/nand as it would be less used during development/testing. usage: <image name> ram <start address> <size> eg. kernel ram 0x81000000 0x1000000 Downloading images to RAM using DFU is not something new, this is acheived in openmoko also. DFU on RAM can be used for extracting RAM contents to host using dfu upload. Perhaps this can be extended to io for squeezing out register dump through usb, if it is worth.

| | | | | | | | | | | | | | | | | | | Previously we didn't support upload/download larger than available memory. This is pretty bad when you have to update your root filesystem for example. This patch removes that limitation (and the crashes when you transfered any file larger than 4MB) by making raw image writes be done in chunks and making file maximum size be configurable. The sequence number is a 16 bit counter; make sure we handle rollover correctly. This fixes the wrong transfers for large (> 256MB) images. Also utilize a variable to handle initialization, so that we don't rely on just the counter sent by the host.
