Sure would be happy to do so!
Unfortunately I am now running into another issue that appears to be related to one you saw earlier where I get ERROR: first sector must be <= last.
I am now trying to flash something a bit more substantial than just those from the quickstart linked above (eventually hoping to port new RTOS, which currently only supports HiFive1), so am unsure if it’s related to your post/the original issue.
Would you prefer to wait on filing the issue, or just go ahead with potentially limited scope?
