ESP32S2: UF2 RunMode is not working #3813

The following code when implemented in esp-idf works fine but doesn't in CPY.

Code Reference: TinyUF2 docs.

(void) esp_reset_reason();
esp_reset_reason_set_hint(0x11F2);

I am working on adding reset-to-uf2 bootloader from cpy.

• esp_reset_reason_set_hint() sets RTC_RESET_CAUSE_REG which is used by TinyUF2 to determine if reset-to-uf2 was requested.
• I can confirm that RTC_RESET_CAUSE_REG is successfully set and is persistent after esp_restart() is called.
• The sdkconfig for both cpy and idf are similar.
