Unable to build using Platform.io with current versions

[hhinma]

I created a new platform.io project today with the VSC plug in, following the instructions in the readme. The Initial compile failed due to one of the masks used in the play_music_date method (I guess something must have changed in a more recent version of one of the libraries) I resolved that by commenting out the function.

Next problem was unresolved symbols in the Adafruit_NeoPixel library. That did not seem to be being linked in, so I added https://github.com/adafruit/Adafruit_NeoPixel.git to the LIB_DEPS in platform.ini. That resolved the linking issues, but the overall build failed because the image ended up too large. Im assuming I am missing something and/or external dependencies have changed since this was documented. Any thoughts?

Exactly ;-) The main reason not updating anything is the size of application that would require different partitioning and thus non working web update. Also the combination of libraries is a little bit picky to make it work reliably. Everything would be possible, but it needs time, that is scarce for me last year.

If you change the partition size, you can build it and the latest libraries seems to be quite reliable and working well. Create partition file eg. min_spiffs.csv and use it. This should work:

'# Name, Type, SubType, Offset, Size, Flags

nvs, data, nvs, 0x9000, 0x5000,

otadata, data, ota, 0xe000, 0x2000,

app0, app, ota_0, 0x10000, 0x1E0000,

app1, app, ota_1, 0x1F0000,0x1E0000,

spiffs, data, spiffs, 0x3D0000,0x30000,
'

I have just successfully flashed a new version for M5Stack Core from PlatformIO.

• I created min_spiffs.csv in root dir
• References this file in platformio.ini: board_build.partitions = min_spiffs.csv
• Flashed into M5 Core

RAM:   [===       ]  29.5% (used 96640 bytes from 327680 bytes)
Flash: [==========]  99.5% (used 1955861 bytes from 1966080 bytes)

It is working.
