When I try to erase chip (STM32L011F4U6) with ST Link utility, it do not works and I get the message "the elf loader is bigger than the ram size", see the enclosed picture.
I use the ST Link side of a NUCLEO-L053R8 board connected to a cutom board with the STM32L011F4U6.
St link connection is ok, and I'm able to read the device memory, so the hardware SWD connection seems to work well.
FYI : when I try to debug the STM32L011F4U6 from the development environment System Workbench for STM32, it does not work either.
I hope you can help me find a solution
