Alejandro, Bernhard,
When using the prebuilt Win32 binaries of "sunxi-fel", which I downloaded
from
"https://ci.appveyor.com/project/linuxsunxi/sunxi-tools/build/artifacts"; I
noticed that in the same situation "sunxi-fel -l" and "sunxi-fel -list" give
a different result.
That is when "sunxi-fel -list" yielded "ERROR: Allwinner USB FEL device not
found!", "sunxi-fel -l" yielded no output whatsoever.
Regards, Jk.
"sunxi-fel -list" is invalid command syntax. The utility only accepts "-l",
"--list" and "list". The "-list" you used is essentially the same as any
other invalid command, say "sunxi-fel foobar".
Unfortunately, the command line parameter handling of sunxi-fel is a bit
quirky. When no valid option-style argument is found, the program will
process remaining arguments only after trying to open an USB connection to
the first device in FEL mode that it detects. This fails in your case,
which is why you end up with "Allwinner USB FEL device not found" instead
of "Invalid command -list".
"sunxi-fel -l" is intended to be 'silent' when no devices are detected.
This is to allow checking for FEL devices within a batch file, where the
exit status would determine if any were found. To actually report failure
you should add the verbose option, i.e. "sunxi-fel -v -l" would tell you
"No Allwinner devices in FEL mode detected".
Did you follow the driver installation procedure as described at
http://linux-sunxi.org/FEL/USBBoot#Using_sunxi-fel_on_Windows ?
To check if your device gets detected at all, please run the listdevs.exe
that is enclosed in the download archive. Make sure that your SoC shows
up with a USB ID of "1f3a:efe8". If that's the case and the proper WinUSB
driver is assigned, sunxi-fel should be able to access it.
