I’m trying to use esp32 OTA and I’m getting a reboot when uploading. It says ELF file "SHA256: 0000000000000000"
. When I googled this I got discussions about this but they were all about the esp-idf platform and I’m using arduino. Also I didn’t understand those discussions because they were from platform developers.
Any ideas about what I’m doing wrong? My build output is …
