Flashing the LED Demo Program

In the most recent batch of HiFive1 boards, some of them were accidentally shipped without the factory image on them, so we’re releasing instructions for re-flashing the HiFive1 to its factory default state. The default image includes the LED fading program, which gives a quick visual indication your HiFive1 is working properly.

From your Freedom E SDK root directory (typically freedom-e-sdk), simply run this script. Here’s a helper script that does all of that at once:

cd freedom-e-sdk
curl https://static.dev.sifive.com/dev-tools/flash_bootloader.sh | sh

As a side note, in case you haven’t already seen it, check out our latest campaign: the HiFive Unleashed.

As always, you can find us on the SiFive forums or on Twitter @SiFiveInc.

SiFive was founded by the creators of the free and open RISC-V architecture as a reaction to the end of conventional transistor scaling and escalating chip design costs.
