Issue uploading to tomu about tomu-quickstart HOT 5 CLOSED

I believe dfu-util needs to be "fixed" for Catalina and the one in Homebrew hasn't been yet.
But I think Arduino has fixed it and has pre-compiled binaries here:
https://github.com/arduino/dfu-utils-cross/tree/master/distrib/osx
Try that and see if it works.

Yep, that worked flawlessly. THANKS!!

Hello @todbot , I'm facing the same issue on macOS Catalina (10.15.7). Already tried the binaries you suggested but the issue persists... Any tips? ty

Hi @rflmota,
I can verify that on MacOS Big Sur (11.1) that the Arduino dfu-util binary and the Homebrew dfu-util both throw the same error of `dfu-util:

[...]
Claiming USB DFU Interface...
Setting Alternate Setting #0 ...
dfu-util: Cannot set alternate interface: LIBUSB_ERROR_OTHER

However I have been able to update Tomu by going to https://dfu.tomu.im/ on Chrome and using that page's WebUSB DFU loader.

This makes me think that Chrome is now somehow claiming DFU devices, preventing other processes from claiming them.

If you do want to use the command-line dfu-util program, I've recompiled it on my Mac and it can reprogram Tomus. It is attached here:
dfu-util-macos-static-19Dec2020.zip

If you want to compile it yourself, the steps I used were:

git clone https://github.com/arduino/dfu-utils-cross
cd dfu-utils-cross

cd libusb-1.0.9
export LIBUSB_DIR=`pwd`
./configure --enable-static --disable-shared
make clean
make

cd ../dfu-util-0.9
USB_CFLAGS="-I$LIBUSB_DIR/libusb/ -framework IOKit -framework CoreFoundation" USB_LIBS="-L$LIBUSB_DIR/libusb/.libs/ -lusb-1.0 -lobjc" ./configure
make clean
CFLAGS=-static make V=s

./src/dfu-util --list
./src/dfu-util -v -d 1209:70b1 -D ../../tomu-quickstart/prebuilt/miniblink.dfu
