Solved "Not enough space" error message when updating firmware on er4.

When I go to upgrade my Radiomaster er4 rx I get the message "Not enough space." Logically I take this to mean their isn't enough memory for the new firmware. Is there a way to get around this (delete old firmware (how?)) or is it stuck at 3.3.1 forever? I reverted back to 3.3.1 on my tx so I can fly, but I wonder about the future.

Almost sounds like you have the wrong file downloaded. I will have to check mine later tonight.

What release are you trying to go to, and what is the name of the firmware file?

I was going to 4.0. My transmitter updated correctly, but I got that error message on the er4. The file name was "firmware.bin" Hmmm, maybe I did make the file with wrong settings. I just did it again and came out with firmware.bin.gz. I'll give that a shot.

I figured it out. I think I did create the wrong file the time it failed. I created another file this time in Expresslrs Configurator and it created "firmware.bin.gz." I extracted the firmware.bin file in it and tried to update but got "Not enough space" again. I then updated using the firmwar.bin.gz file and it worked perfectly. I guess I overthought it the first time. Now I am at 4.0 on both tx and rx. I noticed right away I'm not getting beeps when it binds. Must be some changes in the 4.0 version.
