Description
@fjmolinas realizied that the hifive1 shows a flasing issue.
Somehow, the boards gets into a state where openocd cannot flash it anymore.
There's a "safe bootloader mode" that can be entered by flashing the reset button twice (second time when the led blinks green, after which the led should pulse in red, indicating safe mode). In this the board can be flashed again. Unfortunately that's a manual procedure and thus makes the board unusable in CI or automated testing...
I've bisected the issue to this commit: 547ebd1
Steps to reproduce the issue
BOARD=hifive1 make -Cexamples/hello-world make flash- if it succeeds (depends on previous state), try a second time, should fail
Expected results
Flashing succeeds.
Actual results
Flashing fails.
