anybody else getting some issue flashing the blink firmware to the board?
<https://github.com/efabless/caravel_board/issues/82>

Are you using the blink subdir in the gf180 folder?

I initially was using `firmware/blink` instead of `gf180/blink` and got the same error

(although for whatever reason i was able to get it to flash using that one as well by holding down the reset button for the entirety of the flash process)

in my case all flashed good from 1st attempt:
```python3.8 ../util/caravel_hkflash.py blink.hex
