    There were a few issues with my original setup. First I updated to the latest esptool from 1.2 to 2.0 beta. The tool then notified me that 32m was deprecated in favor of 4MB. Lastly the mode I was using should have been dio and qio. The resulting command that worked after an erase was...

    ./ --port /dev/tty.SLAB_USBtoUART --baud 115200 write_flash \--flash_freq 80m --flash_mode dio --flash_size 4MB \
    0x0000 boot_v1.6.bin 0x1000 espruino_esp8266_user1.bin \
    0x3FC000 esp_init_data_default.bin 0x37E000 blank.bin
