Flash script for linux
To flash an ESP8266 on Linux, you need the esptool as it is shipped with Arduino IDE or as standalone tool, see github source and binary releases.
Felix' script
Felix posted a script in the forum that works like the windows flash.cmd script:
#!/bin/bash read -e -p "Serial Port :" -i "/dev/ttyUSB0" comport read -e -p "Flash Size (example 512, 1024, 4096) :" -i "4096" fsize read -e -p "Build (example 71, 72, ..) :" -i "120" build
size="${fsize}K"
if [ $fsize -gt 1000 ]; then
size=$(($fsize/1024))"M"
fi
echo "Expected Flash Size: $size"
echo "Using com port: $comport"
if [ -f ESPEasy_R${build}_${fsize}.bin ]; then
echo "Using bin file: ESPEasy_R${build}_${fsize}.bin [FOUND]"
./esptool -vv -cd nodemcu -cb 115200 -bz $size -cp $comport -ca 0x00000 -cf ESPEasy_R${build}_${fsize}.bin
else
echo "Expected bin file: ESPEasy_R${build}_${fsize}.bin [NOT FOUND!!!]"
fi
Thonshic's script
The following script tries to find the esptool binary
- in Arduino IDE install paths
- in a dir of the PATH variable
- the local directory (with the script and firmware files)
You get a choice of firmware files, either with dialog or by number.
#!/bin/bash
selectst=""
for i in ESPEasy*bin
do
selectst="$i $i off $selectst"
done
# check for esptool
esptoolbin=$(which esptool)
if [ ! -x "$esptoolbin" ] ; then
if [ -x "./esptool" ] ; then
esptoolbin="./esptool"
else
eardu=$(find $HOME/.arduino15/packages/esp8266/tools/esptool/* -name esptool|sort|tail -1)
if [ -x "$eardu" ] ; then
echo "found esptool: $eardu"
esptoolbin="$eardu"
fi
fi
fi
if [ ! -x "$esptoolbin" ] ; then
echo "esptool not found, you can link it here or put in \$PATH"
exit 2
else
echo "using esptool $esptoolbin"
fi
read -e -p "serial device, (USB2serial devices: $(ls /dev/ttyUSB*)):" -i "/dev/ttyUSB0" serdev
if [ ! -r "$serdev" ] ; then
echo "device '$serdev' does not exist"
exit 2
fi
if [ -n "$(which dialog)" ] ; then
cmd=(dialog --radiolist "Select firmware" 22 76 16)
choice=$("${cmd[@]}" ${selectst} 2>&1 >/dev/tty)
else
# bash only, do it with an array
fa=(ESPEasy_*.bin)
cnt=0
nfa=${#fa[*]}
while [ $cnt -lt $nfa ]
do
echo $cnt ${fa[$cnt]}
((cnt++))
done
read -p "choose number of firmware file to flash [0-$((nfa-1))]: " nsel
choice=${fa[$nsel]}
if [ ! -f "$choice" ] ; then
echo "cannot find file \"$choice\", exiting"
exit 2
fi
fi
echo "----"
read -p "flash $choice? [Y/n]" yn
if [ "$yn" != "n" ] ; then
"$esptoolbin" -vv -cd nodemcu -cb 115200 -cp "$serdev" -ca 0x00000 -cf "$choice"
fi
Example output
