determine flash size - Everything ESP826

As I didn't want tot flash nodemcu just to determine the flash size I ended up looking at their code and realized it's all available in spi_flash.h in the SDK (not the size directly but the manufacturer/device ID): uint32 spi_flash_get_id(void); The first ESP-12 I checked actually has a Winbond W25Q32BV - not 512kB but 4M platforma wrote:... how to determine your flash size manually. With your ESP in bootloader mode, use the esptool.py that comes with the pfalcon/esp-open-sdk (change the port accordingly): Code: Select al You have basically two options: install a firmware (NodeMCU, Arduino, etc.) and use their functions or extract the flash ID and look it up. Install NodeMCU. Build and flash the NodeMCU firmware.

  1. Flash ESP8266 Firmware using esptool.py, run on Linux with Python 2.7.http://arduino-er.blogspot.com/2015/05/flash-esp8266-firmware-using-esptoolpy.htm
  2. Connecting to the computer for flashing Get your computer ready. Install the serial monitoring program of your choice. Install the drivers for your UART (USB->TTL) converter. Plug in the UART and open the device manager. Under the Ports (COM & LPT) you will notice an additional COM-Port, usually COM3 or higher. Note the number, you may need it. The nodeMCU and the WeMOS use same UART chips.
  3. Flash Size (-flash_size, -fs) Size of the SPI flash. Valid values are 4m, 2m, 8m, 16m, 32m, 16m-c1, 32m-c1, 32m-c2 (megabits). For write_flashcommand, the default is detect, which tries to autodetect size based on SPI flash ID. If detection fails, older default of 4m (4 megabits, 512 kilobytes) is used. This parameter can also be specified using the environment variable ESPTOOL_FS. The.
