Loading :advanced Code into an Unmodified WROVER running Espruino

You can load ClojureScript :advanced code directly into an ESP32 WROVER running Espruino for execution upon boot, by creating a binary and flashing it to the JavaScript "boot ROM" area. This has the same effect as when loading code via the Espruino Web IDE, in the "Direct to Flash (execute code at boot)" mode, but flashing is much quicker and more reliable.

Note: To do this, you'll need an ESP32 WROVER with SPI PSRAM, as opposed to just a WROOM, as the ClojureScript in this example uses more RAM than is available in the WROOM.

Create :advanced Code

Here is a small program that uses enough to pull in data structures, etc, leading to nearly 100 KiB:
