I'm not shure what do you mean by "root message" ?!pythoncoder wrote: ↑Fri Feb 16, 2018 7:02 am@loboris Thanks for that. A pointer to the build wiki in the root message would help newcomers to your fork and also ensure you only have one doc to maintain.
I'm still foxed as to why I can only access SpiRAM using a pre-built firmware image. Are further config options required to set the heap size?
There is only one help system, the Wiki.
If you mean the README.md in the base repository directory, there is a link to the Wiki:
Wiki pages with detailed documentation specific to this MicroPython port are available.
According to your post, you can access spiram, but only 512 KB. Have you set the larger value in menuconfig (Micropython --> System settings --> Micropython heap size) before build ?
