NXP LPC microcontroller
Overview
Local notes page for NXP LPC family MCUs.
On-chip flash in at least one LPC part gives an error when reads attempted on erased but not written areas of flash. Github Zephyr RTOS issue from 2020:
Question, is NXP's proprietary flash firmware driver for on-chip / MCU flash needed for applications which run on LPC but don't use on-chip flash other than for program text? Questions go to Kconfig symbol SOC_FLASH_MCUX and seeming associated device tree node `/soc/peripheral@50000000/flash-controller@34000`. A search of Zephyr 3.7.0 source tree shows:
