My project crashed during programming of STM32L152 internal flash.
Crashing means, that I cannot halt CPU; no hard fault nor bus fault interrupt only CPU freezed.
Project runs CMSIS-RTX RTOS. Program is running in a separated area of flash.
It is separated in linker file. Flash programming routine (half page write) is running from SRAM.
Have anyone an idea what the problem could be?
