I am trying to upload or flash the wled bin file to my esp32 wroom. I have installed the esptool to my linux computer via a terminal. I have downloaded the wled bin file and used this cmd line from [Install WLED Binary - WLED Project](https://kno.wled.ge/basics/install-binary/) .

esptool write-flash 0x10000 ./WLED\_0.15.3\_ESP01.bin

But all that does is return a list of usages for the esptool.

What is the correct cmd or syntax to flash my esp32 in a linux terminal.

Thanks

It won’t install from WLED, as I have tried and better tried. When I click on install, it just goes to preparing installation for ever. I have pressed the boot button to no avail. Thanks anyway

Ok, I worked it out , the actual syntax was wrong on the website I got the instructions from. the wled bin file was uploaded ok with no errors but the led strip , which is supposed to be ws1812 is not working from a 5v supply. It does light up on another esp32, but not on the one I have just uploaded the bin file.
