Re: ESP32 Automatic flash error

The procedure to enter the bootloader mode is quite simple:

  • press and hold the BOOT button
  • press and release the EN button
  • release the BOOT button.
Flash your firmware.

You don't need to change anything.

Re: ESP32 TFT display library

Everything should work with the updated library the same as with the old one. The display cannot be added to the "wrong bus". The bus used is defined at the begining of the tft_demo.c . The default bus is now 1 (HSPI), maybe it was 2 before, but it should not affect the operation. Please c...

Re: ESP32 WROVER pSRAM Quiescent current

Maximal standby current of ESP-PSRAM32 is 50 uA, but it is powered by VDD_SDIO and is powered down before entering deep sleep (same as Flash chip).
As a result, there is no difference in current consumption in deep sleep between ESP32 WROVER and ESP32 WROOM Module.
