cmd: dfu: Propagate error if dfu gadget fails

2021-04-23T06:45:55+00:00

On systems without usb gadget dfu core fails which was reported by error
but command itself returns pass which breaks any usage in a script.
That's why propagate error from run_usb_dnl_gadget().

dfu: add support for the dfu_alt_info reintialization from the flashed script

2021-01-31T13:08:56+00:00

Reinitialize DFU USB gadget after flashing the 'SCRIPT' entity to ensure
that the potential changes to the 'dfu_alt_info' environment variable are
applied.

command: Remove the cmd_tbl_t typedef

2020-05-18T22:36:55+00:00

We should not use typedefs in U-Boot. They cannot be used as forward
declarations which means that header files must include the full header to
access them.

Drop the typedef and rename the struct to remove the _s suffix which is
now not useful.

This requires quite a few header-file additions.

dfu: Add optional timeout parameter

2020-01-07T13:37:50+00:00

When the `dfu` command is called from the U-Boot environment,
it now accepts an optional parameter that specifies a timeout (in seconds).
If a DFU connection is not made within that time the `dfu` command exits
(as it would if Ctrl+C was pressed). If the timeout is left empty or being
zero the `dfu` command behaves as it does now.

This is useful for allowing U-Boot to check to see if anything wants to
upload new firmware before continuing to boot.

The patch is based on the commit
https://github.com/01org/edison-u-boot/commit/5e966ccc3c65c18c9783741fa04e0c45e021780c
by Sebastien Colleur, which has been heavily reworked due to U-Boot changes
in the past.

dfu: Refactor do_dfu() to handle optional argument

2020-01-07T13:37:50+00:00

In the future we may utilize optional argument in 'dfu' command line.
As a preparation for this, refactor do_dfu().

dfu: allow to manage DFU on several devices

2019-10-31T11:12:31+00:00

Add support of DFU for several interface/device
with one command.

The format for "dfu_alt_info" in this case is :
-  '='alternate list (';' separated)
- each interface is separated by '&'

The previous behavior is always supported.

One example for NOR (bootloaders) + NAND (rootfs in UBI):

U-Boot> env set dfu_alt_info \
"sf 0:0:10000000:0=spl part 0 1;u-boot part 0 2; \
u-boot-env part 0 3&nand 0=UBI partubi 0,3"

U-Boot> dfu 0 list

DFU alt settings list:
dev: SF alt: 0 name: spl layout: RAW_ADDR
dev: SF alt: 1 name: ssbl layout: RAW_ADDR
dev: SF alt: 2 name: u-boot-env layout: RAW_ADDR
dev: NAND alt: 3 name: UBI layout: RAW_ADDR

U-Boot> dfu 0

$> dfu-util -l

Found DFU: [0483:5720] ver=9999, devnum=96, cfg=1,\
 intf=0, alt=3, name="UBI", serial="002700333338511934383330"

dfu: Avoid declaring unused variables and absent parameters

2019-04-21T08:26:51+00:00

The compiler is not happy when neither USB nor TFTP transport for DFU defined:

cmd/dfu.c: In function ‘do_dfu’:
cmd/dfu.c:31:8: warning: unused variable ‘devstring’ [-Wunused-variable]
  char *devstring = argv[3];
        ^~~~~~~~~
cmd/dfu.c:30:8: warning: unused variable ‘interface’ [-Wunused-variable]
    char *interface = argv[2];
          ^~~~~~~~~

Surround those variables by #ifdef expression.

More serious, that comes under same circumstances, is a compilation error due
to absence of macro parameter:

In file included from include/image.h:45,
                 from include/common.h:35,

Put empty string unconditionally to have macro parameter present.

SPDX: Convert all of our single license tags to Linux Kernel style

2018-05-07T13:34:12+00:00

When U-Boot started using SPDX tags we were among the early adopters and
there weren't a lot of other examples to borrow from.  So we picked the
area of the file that usually had a full license text and replaced it
with an appropriate SPDX-License-Identifier: entry.  Since then, the
Linux Kernel has adopted SPDX tags and they place it as the very first
line in a file (except where shebangs are used, then it's second line)
and with slightly different comment styles than us.

In part due to community overlap, in part due to better tag visibility
and in part for other minor reasons, switch over to that style.

This commit changes all instances where we have a single declared
license in the tag as both the before and after are identical in tag
contents.  There's also a few places where I found we did not have a tag
and have introduced one.

dfu: Fix up the Kconfig mess

2018-02-21T19:28:15+00:00

Clean up the screaming mess of configuration options that DFU is.
It was impossible to configure DFU such that TFTP is enabled and
USB is not, this patch fixes that and assures that DFU TFTP and
DFU USB can be enabled separatelly and that the correct pieces
of code are compiled in.
