The generated setup is available, see link below

Yes, thanks for checking, English is neither Premek nor my
specialty and Pemek.

There would be happy even to provide build binary to everybody who cares.

But generally the hardware needs more work to be done.
Unfortuantelly, flashing to the MCU is quite complicated due
un-documented algorithm. We have used Ti tools to Flash setup
code. But we know other working solution, it is possible to
setup MCU over JTAG and the download flasher code into internal
RAM. The library with flash algorithm is available from Ti
in binary form for Cortex-R4F. So our plan is to have small
loader to allow flash application over CAN or ETHERNET.

But it is still longer term goal.

Best wishes,
