Blink on pin 6 (active low). This is where the LED (active high) is on Sparkfun's RED-V Thing Plus.
It is also
SPI1_SCK pin, and the default bootloader assigns it the SCK function, because it is trying to communicate with the ESP32 (over SPI) that's present of the HiFive1 Rev B board. And of course it does not clean up, so we need to do it ourselves.
Delay uses CLINT/mtime counter.
No stack, interrupts, nothing.
