Description: This was kind of a fun one that you might find useful someday like I did. Esptool git reference: github.com/espressif/esptool Flash chip datasheets: winbond.com/hq/product/code-storage-flash-memory/serial-nor-flash/?__locale=en&selected=128Mb#Density Here's all of those commands you can use as a starting point and note that on windows, things will be slightly different. Just follow the same steps and you should be good: Read from Adafruit Huzzah board (4MB): /Users/kevindarrah/Library/Arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py --port /dev/cu.usbserial-01D5ECE0 --baud 921600 read_flash 0 0x400000 adafruit.bin Write back to Adafruit Huzzah: /Users/kevindarrah/Library/Arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py --chip esp32 --port /dev/cu.usbserial-01D5ECE0 --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x0 /Users/kevindarrah/adafruit.bin Get Flash ID for size: /Users/kevindarrah/Library/Arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py --port /dev/cu.usbserial-DA00Y7QG --baud 921600 flash_id Read trigBoard (16MB): /Users/kevindarrah/Library/Arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py --port /dev/cu.usbserial-DA00Y7QG --baud 230400 read_flash 0 0x1000000 trigBoardbackup.bin Write trigBoard: /Users/kevindarrah/Library/Arduino15/packages/esp32/tools/esptool_py/2.6.1/esptool.py --chip esp32 --port /dev/cu.usbserial-DA00Y7QG --baud 921600 --before default_reset --after hard_reset write_flash -z --flash_mode dio --flash_freq 80m --flash_size detect 0x0 /Users/kevindarrah/trigBoardbackup.bin Tindie link to trigBoard: tindie.com/products/kdcircuits/trigboard-ultra-low-power-esp32-iot-platform Thanks to all the Patrons for dropping a few bucks in the tip jar to help make these videos happen! patreon.com/kdarrah Twitter: twitter.com/KDcircuits For inquiries or design services: kdcircuits.com
