Crashes on H713

user@user-ghostbsd ~/sunxi-tools % ./sunxi-fel version
Assertion failed: (strcmp(buf, "AWUS") == 0), function aw_read_usb_response, file fel_lib.c, line 158.
zsh: abort (core dumped)  ./sunxi-fel version

user@user-ghostbsd ~/sunxi-tools % ./sunxi-fel  spiflash-info
Assertion failed: (strcmp(buf, "AWUS") == 0), function aw_read_usb_response, file fel_lib.c, line 158.
zsh: abort (core dumped)  ./sunxi-fel spiflash-info

user@user-ghostbsd ~/sunxi-tools % dmesg 
ugen1.15: <vendor 0x1f3a product 0xefe8> at usbus1

I compiled sunxi-fel on FreeBSD with:

git clone https://github.com/linux-sunxi/sunxi-tools/
cd sunxi-tools
sudo pkg install dtc
sudo ln -s /usr/local/lib/libfdt* /usr/lib
sudo ln -s /usr/local/include/fdt.h /usr/include
sudo ln -s /usr/local/include/libfdt* /usr/include
gmake

Then followed this procedure on my H713 based projector:

• Disconnect the power cable entirely
• Use a USB A to USB A cable and connect it to the host OC
• A red LED comes up on the projector (note that it is ONLY connected via USB, power is NOT attached)
• Press the power button
• dmesg shows <vendor 0x1f3a product 0xefe8> at usbus1 ("sunxi SoC OTG connector in FEL/flashing mode")
• On the host PC use a tool like sunxi-tools

Feel free to contribute proper H713 support to the project based on this work.

I tried with Copilot but it doesn't quite work yet, as I continue to get

i:~/sunxi-tools$ sudo ./sunxi-fel versiony
sunxi-fel: fel_lib.c:180: aw_read_usb_response: Assertion `strcmp(buf, "AWUS") == 0' failed.
Aborted

Someone with more knowledge of the subject needs to look into this.
