0.1.5-dev not working flash

[antohami]

I made a backup of the u-boot partition, cleared the partition, tried to write it. As a result, such an error:

Traceback (most recent call last):
File "/usr/lib/python3/site-packages/usb1/init.py", line 282, in create_initialised_buffer
return string_type.from_buffer(init), init
TypeError: memoryview: a bytes-like object is required, not 'str'

During handling of the above exception, another exception occurred:

Traceback (most recent call last):

I can confirm this happening here too anytime you want to flash. Reverting back to commit e43cb3d which was before the python3 port makes it work again.

I had the same issue, here's how I fixedit:

src/rkflashkit/rktalk.py on line 289

+++ self.__dev_handle.bulkWrite(self.__write_endpoint, buf)                    # this works
--- self.__dev_handle.bulkWrite(self.__write_endpoint, str(buf))
