I'm thinking my memory.x isn't correct. I'm testing the STM32L4 Discovery kit for the IoT node (B-L475E-IOT01A)

I'm confused because this target has two RAM entries on the probe.rs target page: https://probe.rs/targets/master/STM32L475VGTx 

The manual says: STM32L4 Series MCU based on Arm® Cortex®-M4 core with 1 Mbyte of
Flash memory and 128 Kbytes of SRAM, in LQFP100 package

This is different that the target described in probe.rs

I get the following error when I try to flash using the following command: 

cargo flash --target thumbv7em-none-eabihf --chip STM32L475VGTx

Any ideas? memory.x off?
