romfs — ROMFS helper utilities

The romfs module provides helper utilities for inspecting the read-only filesystem (ROMFS) mounted at /rom.

Functions

romfs.ls_romfs() → None

Lists every file present in the ROMFS mounted at /rom and prints diagnostic information about each entry to stdout.

For each file, the following information is printed:

  • addr: The memory address of the file’s data, masked to 28 bits and formatted as an 8-digit hexadecimal value.

  • size: The size of the file in bytes, obtained from the length of a memoryview of the open file.

  • alignment: The largest power-of-two alignment (checked against 128, 64, 32, 16, 8, 4) that the file’s address satisfies. If the address is not aligned to any of these boundaries, NOT aligned is printed instead.

  • name: The file name within /rom.

This function takes no arguments and returns None.
