Mos console triggers POWERON_RESET

When running mos console from linux, the device (esp32) I am communicating with (via serial) always reboots, and logs…
[Nov 26 18:17:17.382] rst:0x1 (POWERON_RESET),boot:0x3b (SPI_FAST_FLASH_BOOT).
However when running mos console from windows, I am able to hook into the current running program, without restarting/rebooting the device.

It would be nice to be able to connect to a device in it’s current state, and see it’s output. I also believe this POWERON_RESET is causing my device to go into DOWNLOAD_BOOT mode

[Nov 26 18:18:06.589] rst:0x1 (POWERON_RESET),boot:0x20 (DOWNLOAD_BOOT(UART0/UART1/SDIO_FEI_FEO_V2))
[Nov 26 18:18:06.594] waiting for download

when mos console is called (from linux) while the device is in a specific state (possibly a specific issue to my device design/hardware).

What is causing this reboot? And is it possible to not trigger this reboot when using mos console from linux?


Try mos console --set-control-lines=false if you don’t want the device to be reset when running mos console. The Windows drivers do not always handle the DTR/RTS lines corectly.

This works beautifully. Thank you very much for the response!


Apologies for reviving the topic, but it seemed more relevant to revive and keep the thread history than start a new thread.

I seem to be seeing this for the first time since updating macOS to Big Sur. And using

mos console --set-control-lines=false

does not seem to resolve the issue.
