Pico start warning

Post by wangshujun@tom.com » Sun Apr 18, 2021 1:56 pm

Question 1:
Warning will be prompted at startup, and the subsequent operation will be normal

WARNING: Could not sync device's clock: can't import name RTC
WARNING: Could not validate time: can't import name RTC
MicroPython v1.14-172-gf842a40df-dirty on 2021-04-18; Raspberry Pi Pico with RP2040

Type "help()" for more information.
>>>

Question 2:
It can only be accessed normally in thonny, but other serial port tools can't access normally. The environment is ST's CDC driver used by winc7 system CDC driver

I haven't seen this using rshell or miniterm.

The warning should go away with latest Thonny (3.3.6).

Don't know anything about the USB driver problem.
