Building ESP-32 GENERIC board using ESP-IDF v4.4 (142bb32c50fa9875b8b69fa539a2d59559460d72) throws memory allocation errors upon py file imports:

Type "help()" for more information.

Cannot reproduce with ESP-IDF v4.0.2 and also with v4.2.2 everything is fine.

IDF 4.4 (and I think 4.3) has a more fragmented IDF heap, and so there is less heap available for MicroPython. On IDF 4.0.2 and 4.2.2 there is about 100k available for MicroPython, but on 4.4 it's only 64000.

See related #7214.

Is this the reason why MPY cannot adapt to idf4 4 ？ Does it need to be repaired by the espressif official?
