libc++abi.dylib: terminating with uncaught exception of type std::length_error: vector about mkspiffs

[igrr]

Error message added in 011c110.

That is most likely caused by the fact that negative partition size (-s -1069056) is given. I think mkspiffs should check and give a better error message here, but you still need to find what calls mkspiffs and why the size is negative.

I've found a corresponding bug on platformio/platform-espressif8266 issue #69. It is said to be fixed in an upstream development branch (newer than current 1.6.0 release).

I was able to work around the problem by using a smaller than 16MB custom flash size by adding these builds flags in my platformio.ini file:

[env:d1_mini_pro]
build_flags = -Wl,-Teagle.flash.4m.ld

Do you want to keep this issue open for fixing the error message?
