8.2.0-rc.0, no echo on REPL on ODroid Go

[fovea1959]

CircuitPython version

Adafruit CircuitPython 8.2.0-rc.0 on 2023-06-23; Hardkernel ODroid Go with ESP32

Code/REPL

None

Behavior

After a powerup and connection via the UART, characters typed in the REPL show up on the screen, but are not echoed to the host PC.

Issuing commands import os os.listdir() causes screen garbage.

import wifi still hangs.

Description

No response

Additional information

Is there a way to disable the onboard screen from echoing the REPL. This and #8069 smell like some sort of bad memory access when scrolling the screen, and disabling the screen would help me debug that.

You can disable the display by calling displayio.release_displays(). With a build you can also comment out all of the display init in the board_init function.

Worth retesting with 9.0.0,but this might be a bunch of different issues, such as UART setup troubles and/or display troubles.
