## Building the example
|
|
|
|
|
|
|
|
|
|
To build the example, make sure sure you have all the tools in your PATH and
|
|
|
|
|
run:
|
|
|
|
|
|
|
|
|
|
`$ gprbuild -f -p -P hifive1_rev_B_example.gpr -XPLATFORM_BUILD=Debug`
|

This will create a folder named `obj` in the same directory with the elf-formated
|
|
|
|
|
binary plus some auxiliary files. Inside this folder run the following command
|
|
|
|
|
to create the `hex` file:
|
|
|
|
|
|
|
|
|
|
`$ riscv32-elf-objcopy -O ihex main main.hex`
|
|
|
|
|
|
|
|
|
|
This new revision of the HiFive board allows the `hex` file to be uploaded
|
|
|
|
|
through the USB connection that should appear in your file manager. Just copy
|
|
|
|
|
the newly created `main.hex` into the board and press the restart button.
|
|
|
