What version of the espressif8266 platform are you running? (pio platform show espressif8266 and it’s right at the top under the summary - for reference I was running 2.5.1, but updated to 2.5.2). I also have just looked for and seen the option missing for a project that has a file system folder but I am also running beta versions of PlatformIO and the VSCode extension.
@ivankravets @valeros Is this related to changes made to support the PlatformIO 2.0.0 VSCode extension? As I just noticed that I don’t have a ‘Upload File System Image’ option on a ESP8266 project either on the beta5 (on Linux).
Edit: Correction - I just spotted it… it’s under the environment specific ‘Platform’ tasks… which unfortunately doesn’t show under ‘Generic’ (now General) if there is only one environment in the project.
