This page contains some notes getting LittleFS running using parts of the internal flash memory. For now this will be targeting Black Pill boards with the STM32F411 MCU.

STM32F411CEUX_FLASH.ld
defines the layout of the memory - both flash and ram of the STM32F411 MCU. At the beginning is:
/* Memories definition */
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 128K
FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 512K
}
