I get this when I upload to my ESP32:
␛[0;32mI (259) cpu_start: Chip Revision: 1␛[0m ␛[0;33mW (260) cpu_start: Chip revision is higher than the one configured in menuconfig. Suggest to upgrade it.␛[0m
Do I need to fix it?
If so, how does one do that? (i.e. How do I follow the “Suggest to upgrade it.” comment?)

Using an ESP32-PICO chip, building against this version of MicroPython https://g… ithub.com/micropython/micropython/commit/d96391aca34eb4d516945b34f0bbebf807c41299
I'm seeing a new warning in the debug output.
`W (155) cpu_start: Chip revision is higher than the one configured in menuconfig. Suggest to upgrade it.`

How can I upgrade my targetted chip revision?
You need to adapt the macros CONFIG_ESP32_REV_MIN_0
and CONFIG_ESP32_REV_MIN_1
to respectively 0 and 1 in the sdkconfig.h
of your project.

the sdkconfig.h file now contains and there is no complaint:
#define CONFIG_ESP32_REV_MIN_0 0
#define CONFIG_LOG_DEFAULT_LEVEL 3
#define CONFIG_FREERTOS_ASSERT_ON_UNTESTED_FUNCTION 1
#define CONFIG_TIMER_QUEUE_LENGTH 10
#define CONFIG_ESP32_REV_MIN 1'''
But, note it was:
```#define CONFIG_ESP32_REV_MIN 1```
Not:
```#define CONFIG_ESP32_REV_MIN_1 1```
