Not sure if the os support mapping external memory to heap. You can try to allocate about 300KB space to see if SPI RAM works.

160x120x3 = about 57KB, which is still allocated in the internal memory. It seems you didn't successfully enable the SPI RAM. You may transfer this issue to [esp-idf](https://github.com/espressif/esp-idf).

可能是没有设置好esp-idf？`git submodule update --init`
