1. STM32PRGFW-UTIL overview[edit | edit source]
STM32PRGFW-UTIL package provides embedded software applications to manage the One-Time Programmable (OTP) memories on STM32MP1 series and STM32MP2 series.
It is alternative to the use of U-Boot component described in article How to fuse OTP but of course U-Boot services are still available.
This package also support PMIC NVM programming.
1.1. Package overview[edit | edit source]
