Hello,
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
Thanks !
Thomas

I have changed the MCU on the board with a new one, and I tried to program the chip with a Segger ARM Flasher, and same problem :
Programming and verifying target (5372 bytes, 1 range) ...
- Connecting ... - Connected successfully - Start of preparing flash programming - ERROR: Failed to prepare for programming.Failed to execute RAMCode for RAM check! - End of preparing flash programming - ERROR: Failed to program and verify targetDisconnecting ... - Disconnected2017-11-27 02:50 AM
And here is the schematic.
The 3V power supply is stable.
