Flashing STM32L15X EEPROM with STLink under Linux

Tags: Embedded, Linux, Programming

For a while now I've been evaluating some 32-bit micro controllers for a future product. One of them was the STM32L15x series. There are some handy development boards available such as the Nucleo boards. Since we need to have the ability to program processors from Linux for our small production line, tool support is one of the checkboxes that need to be ticked.

For the STM32 series, flashing the microcontroller can be done through GDB, OpenOCD, and the STLink tool. One issue that arose however was the need to program the EEPROM available on the STM32L series. This requirement comes from need to generate and program different EEPROM content on a per board basis at the production line. Doing that requires a few tweaks that are documented below...
