Unable to disable FPGA autoloading #775

Closed zodiacTiger closed 4 years ago

zodiacTiger commented 4 years ago

I had my bladeRF 2.0 set to autoload the FPGA from flash. Recently I decided to revert back to manual loading. I tried this on my macbook and an ubuntu laptop, but I've had no luck. I'm baffled by the error messages. Notice that a segfault occurs. Could my SPI flash be damaged?

Any help would be appreciated, thanks.

I was able to erase the FPGA and disable the autoloading function by using an older mac desktop that (presumably) had older versions of libusb and libbladerf. I'm suspicious that the problem may exist within those pieces of software because I experienced the problem on Linux Ubuntu VM, 2015 macbook pro, and 2017 mac desktop.
