Dev board is powered with USB cable from port on good computer.
So, it really shouldn't be the power issue.

ESP32 reboots when enable SPI
While developing firmware we stumbled upon very strange behaviour. We have ESP32-WROVER with SPI chip MCP23S09 connected to it. But after trying to initialize SPI, ESP32 reboots. Interesting thing is that if we use ESP32-WROOM, then this problem does not happen. Here is sample application (can use d...
