WebJan 13, 2024 · The SPI flash peripheral actually was initially created to interface with SPI flash chips, which have a d, q, clk, wp and hd pin. I can imagine the SPI port pins are somewhat weird if you aren't familiar with that. For MISO and MOSI, it is explained in the page you quoted: int spid_io_num. GPIO pin for spi_d (=MOSI)signal, or -1 if not used. WebJul 18, 2024 · Hi, from ESP32 Technical Reference Manual: SPI_WP This bit determines the write-protection signal output when SPI is idle. 1: output high; 0: output low. (R/W) Modifying this bit changes output level of WP pin but it is kept all the time high / low - it does not change during SPI transmission. Tried both with user transmission and flash ...

WebThe WP and HOLD pins of the SPI flash chip are not wired to the correct GPIOs of the Espressif chip. These pins must be connected correctly for quad modes to work, and not all boards/modules connect them at all. The SPI flash chip does not support quad modes.
