  --flash_size 4MB-c1

  for all 4MB board features

  I tried

  esptool.py --port COM4 --baud 460800 write_flash --flash_freq 80m --flash_mode qio --flash_size 4MB-c1 0x0000 "boot_v1.6.bin" 0x1000 espruino_esp8266_user1.bin 0x3FC000  esp_init_data_default.bin 0x3FE000 blank.bin
  

  so

  esptool.py --port COM4 --baud 460800 write_flash --flash_size 4MB-c1 --flash_mode dio 0 .\espruino_1v99_esp8266_4mb_combined_409­6.bin

  I have the same problems with Amika (NodeMCU v2 CP2102).
  I can not find a solution for a long time
  But I was surprised when I saw what was displayed Putty and ESPlorer

  In IDE espruino tried everything in speed options - does not work.
  Putty only works on 115200

  I am having a similar problem with a NodeMCU. I tried the line in (post 8) that helped the topic starter, but to no avail.

  I have the same problem on the same ESP8266 V2 (NodeMCU from Amica) board.
  I tried all the versions firmware but I can not find a solution to the problem.

  Under the esplorer and ardiono IDE board works great.

  I have been using ESP32s (dev kit1) with ESPriino for a long time and have not seen such problems.

  port speed: 115200 (I tried different 9600-115200)
