Firmware update targeting 16MB RTK Surveyor fails on 4MB RTK Surveyor: esp32 boot loop #207
Description
SparkFun RTK Surveyor. With RTK_Surveyor_Firmware_v2_0.bin loaded a firmware upgrade of RTK_Surveyor_Firmware_v2_2.bin from the SD card fails because there is no room on the partition:

So, going for the command line method, the automatic download mode does not seem to work and esptool times out waiting for the device. I then manually put the ESP32 into download mode by shorting IO0 (pin 25 per datasheet) to GND and cycling the on/off switch, and verified with esptool (git 65f86142 from today 20th-June-2022) and its chip_id command; That seems to be working:
user@host:~/path/esptool.git$ python3 esptool.py --chip esp32 --port /dev/ttyUSB0 --baud 921600 --before default_reset --after hard_reset chip_id

Unfortunately the RTK Surveyor is now not working correctly the ESP32 never makes it to the firmware:
