Sparkfun ESP32 Thing

OK I used dio, like so..

/Users/oconnd1/Documents/Arduino/hardwar­e/espressif/esp32/tools/esptool.py --chip esp32                                \
        --port /dev/cu.usbserial-DN02MPA4                         \
        --baud 921600                               \
        --after hard_reset write_flash              \
        -z                                          \
        --flash_mode dio                            \
        --flash_freq 40m                            \
        --flash_size detect                         \
        0x1000 bootloader.bin                       \
        0x8000 partitions_espruino.bin              \
        0x10000 espruino_1v99_esp32.bin

Although I flashed MicroPython with..

/Users/oconnd1/Documents/Arduino/hardwar­e/espressif/esp32/tools/esptool.py --chip esp32                                \
        --port /dev/cu.usbserial-DN02MPA4                         \
        --baud 921600                               \
        --after hard_reset write_flash              \
        -z                                          \
        --flash_mode dio                            \
        --flash_freq 40m                            \
        --flash_size detect                         \
        0x1000 ~/Downloads/esp32-20180808-v1.9.4-443-gc­1c798fbc.bin

and that worked.

I'll try qio tomorrow for Espruino tomorrow and see how I go, thanks.
