Re: MicroPython on ESP32 with SPIRAM support-UART event queue full
I am using the M5STACK with 4MB psRAM. The firmware is the lastest version of MicroPython_LoBo_esp32_psram_all. The uart was defined as uart = UART(1, baudrate=19200, bits=8, rx=21, tx=22, timeout=10). When I received some data from the RX of the uart, the error of uart: UART event queue full emerge...

That's why I failed everytime in the past. For the firmware without SPIRAM support from http://micropython.org/download, it's enough to to fl...

Re: MicroPython on ESP32 with SPIRAM support
I have two ESP32 boards: M5STACK with 4M SPIRAM and ESP-WROOM-32. Both of them can flash the standard Firmware successfully from http://micropython.org/download and work well. But both of them failed to flash the firmware with SPIRAM firmware from https://github.com/loboris/MicroPython_ESP32_psRAM_L...
