I would like to dump the current values of otadata. For this purpose, I'm using otatool.py.
With this command
Code: Select all
esp512/esp-idf/components/app_update/otatool.py -p /dev/ttyUSB1 -b 460800 read_otadata
Code: Select all
Running /usr/bin/python /home/ju/tools/esp-idf/components/esptool_py/esptool/esptool.py --port /dev/ttyUSB1 --baud 460800 read_flash 32768 3072 /tmp/tmpyttebszk...
