I would like to be able to save data directly to an external flash on a custom PCB with an ESP32-S3 as part of my production line Describe the solution you'd like I would like support for Custom SPI Pin Configuration in esptool.py for ESP32-S3 devices, I am trying to target SPI2...
Due to IO pin constrain I want to use GPIO 8(strapping pin) as IO for led toggle while running application. After module reset, in main I do below gpio configuration, gpio_config_t io_conf = {}; io_conf.pin_bit_mask = 1ULL << GPIO_NUM_8; io_conf.mode = GPIO_MODE_OUTPUT;...
Because GPIO0 is a strapping pin for entering UART flashing mode on reset, care must be taken when also using this pin as EMAC_TX_CLK. If the clock output from the PHY is oscillating during reset, the ESP32 may randomly enter UART flashing mode. One solution is to use an additional GP...

Could you please explain me the difference between a configuration where the VDD_SPI is powered via 1,8V LDO Internal regulator and a configuration where VDD_SPI is powered via VDD3P3_RTC pin ? Which SPI is concerned with this configuration ? Is it the SPI that is connected to the Flash...
The ESP32 has two I2C channels and any pin can be set as SDA or SCL. When using the ESP32 with the Arduino IDE, the default I2C pins are: GPIO 21 (SDA) GPIO 22 (SCL) If you want to use other pins when using the wire library, you just need to call: ...
