Error encountered with pio remote run

I am seeing a couple different errors using pio remote run. My current setup:

  • VM that holds my project for esp32-c6 dev kit
  • Local on my mac, I have the hardware plugged in and am running pio remote agent start

My platform ini:

build_flags =

platform = espressif32
board = esp32-c3-devkitm-1
framework = espidf

I’m basically just building a hello world that grabs some details about the board and writes to console. Have flashed this previously via pio remote run -t upload -r -e c6 -v (notice the -r) but I’ve ran into other issues here that I’m avoiding by building locally (to the VM that is) and then flashing the output to the device via pio remote run -t upload -e c6 -v . Everything builds fine, but when it goes to upload, I see the following error:

*** [upload] Error 2

It looks like the command to flash isn’t specified correctly and I’m missing an address, but not sure where I should specify that (or why I need to). Any thoughts on what I can do here?

When I try --force-remote, 90% of the time I’ll see an error Agent has been terminated with a BananaError output from the agent with string too long. I prefer not using --force-remote anyway so I’m trying to get this working without.

If the flashing command doesn’t include the proper address for the firmware, it’s a bug. Please file one in if not already present.
