ESP8266 soft-reset after uos.uname()
Hardware:
a- RPiZero + ESP8266 pHAT
(RPi power supply from USB (LCD TV)
RPi HDMI to LCD TV HDMI )
b- microUSB RPi to 7 ports Manhattan USB Hub
c- Powerbank for power supply to USB Hub.
Software:
I start an REPL session with :
screen /dev/ttyACM0 115200
At the micropython prompt typing uos.uname() I have :
(sysname='esp8266', nodename='esp8266', release='2.0.0 (5a875ba)',
version='v1.8.7-7-gb5a1a203 on 2017-01-09', machine='ESPmodule with ESP8266)
I continue typing a lot of micropython command until I repeat
uos.uname() having the following different output with a soft-reset
(sysname='esp8266', nodename='esp8266', release= ets Jan 8 2013,
rst cause: 2, boot mode: (3,6)
and an ( in my opinion ) anomalous characters dump on the screen.
The REPL environment results blocked and I need to reboot the RPI to be able to open a new REPL session.
In the jpg attachments we have a visual description of the reset problem.
Thanks
