Problems with V92 and wifi.save() on ESP8266 512K Flash Boards?

Thank you @MaBe

This worked for me (leaving off the flash size, and using bin locations for larger chip:

python "MYPATH\esptool.py" --port COM4 --baud 115200 write_flash --flash_freq 40m --flash_mode qio 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0xFC000 esp_init_data_default.bin 0xFE000 blank.bin
