SPI2 mode octal not work

Postby daonguyen_iot47 » Mon Aug 29, 2022 4:22 am

When configuring spi in octal mode. Error message not all required capabilities satisfied and esp32 is reset continuously.
I went into the library and removed the line that checks for SPI_CHECK(missing_flag == 0, "not all required capabilities satisfied.", ESP_ERR_INVALID_ARG);
The esp32 chip is no longer reset, but no data is sent on the 8 data pins even though there is still a clock signal.
Quad mode works fine

ESP32 does not support octal mode. The ESP32S2 and S3 do. Removing the check to see if it's supported, unsurprisingly, does not magically give the ESP32 hardware these capabilities.
