for those finding this blog post the steps to put in programming mode do not work as web install resets the esp which takes it out of programming

I use esptool

see here arendst/Tasmota#19975 (comment)

and with tasmota32s2.factory.bin

this is the script I use. Hold programming down until you see ....

port=$(./port) 
type=$([[ $1 ]] && echo -${1})  
bin=./tasmota32s2$type.factory.bin    
[[ ! $port ]] && echo esp not connected no available tty port && exit
echo flashing $bin to $port
esptool.py  \
         --port $port         \
         --before no_reset               \
         --after hard_reset  \
         --baud 115200                \
         --chip esp32s2                \
         write_flash 0 $bin   

port

for sysdevpath in $(find /sys/bus/usb/devices/usb*/ -name dev); do
    (
        syspath="${sysdevpath%/dev}"
        devname="$(udevadm info -q name -p $syspath)"
        [[ "$devname" == "bus/"* ]] && exit
        eval "$(udevadm info -q property --export -p $syspath)"
        [[ -z "$ID_SERIAL" ]] && exit
        [[ "$devname" == "tty"* ]] && echo "/dev/$devname"
    )
done
