mpremote with mount fails on ESP32 #7485
Description
Re-installed mpremote today - tail end of pip3:
Successfully installed mpremote-0.0.5
ESP32 works OK, with ctrl-d resetting the ESP uneventfully if there is no mount.
With a mount, ctrl-d kills mpremote. In the following, when the REPL appeared I pressed ctrl-d:
>>> [adminpete@capybara]: ~/temp
$ mpremote mount .
Local directory . is mounted at /remote
Connected to MicroPython at /dev/ttyUSB0
Use Ctrl-] to exit this shell
>
MicroPython v1.16 on 2021-06-28; ESP32 module with ESP32
Type "help()" for more information.

MPY: soft reboot

I have seen this issue before (on esp32) but can no longer reproduce it... using current mpremote (not from pip, but also tried that). Maybe it has something to do with boot.py/main.py on the device?

The files
boot.pyandmain.pyboth exist but all lines are commented out with#at the LHS. Hardware is a TTGO T_Display which is an ESP32 without SPIRAM. Firmware isThe fault is consistent on that board. However I have just installed the same firmware on the reference board, ensured it has similar null
boot.pyandmain.pyfiles and I can't reproduce it. So this is a puzzler.jdtsmith commentedon Sep 1, 2021
FYI, my ESP32 board with the crash-on-soft-boot-when-FS-mounted issue is also a TTGO T-DISPLAY.

Ah, this traceback looks the same as an issue I just fixed the other day #8240
The inter-byte timeout during flush wasn't quite long enough during the boot after soft reset, it stopped writing for data then before the board was actually ready.
I would see it every time on one of my esp32 boards, but it never occurred on a second one which had an external different brand usb-serial.

This is most likely fixed by a combination of 5a86d8d and fecfd52, so I'll close the issue. Please reopen/comment if the issue crops up again.
