I'm working on the ESP32 DevKit, and I writing a program on esp32 to send data to UART1(GPIO10, GPIO9), I using a USB-TTL tool to connect the UART1 on ESP32 DevKit to my Mac OS X, and send data to UART1 through a serial tools on the Mac. But when I sent a large data that about 100-700 bytes to UART1, the ESP32 was creash, and the output in the `make monitor` is :
