Flashing instructions for ESP32 about ebusd-esp HOT 3 CLOSED

i used

esptool --chip esp32 -p /dev/ttyUSB0 -b 921600 write_flash 0x00000 ebus-v3_lolin32_factory.bin

(base address for flash 0x0000) which worked for a esp32_devkit_c with wroom-32D chip (maybe a clone, but the pin-layout is as in the documentation)

from ebusd-esp.

I wanted to try the bin image out
using
esptool --chip esp32 -p /dev/ttyUSB0 -b 921600 write_flash 0x0 ebus-v3_lolin32_factory.bin
writes to esp32 with following log
`esptool.py v2.8

gives me following error in the serial console

What I am wondering, is why the latest image is 131kB and the mentioned above is almost 850kB

from ebusd-esp.

maybe you want to have a look at the flash.sh script
the binary isn't just 131kB, so you must have picked the wrong one or downloaded garbage
