STM32F429 - cannot view external memory in Eclipse memory pane.

I have been utilizing Eclipse IDE using GNU tool chain to develop and debug my STM32F429 based project.
The target platform has an external SDRAM memory which configured and managed by the MCU's FMC unit. Even though the SDRAM operation is tested for its operation, the Eclipse memory pane cannot display the contents of external memory addresses when debugging with the arm gdb tools. The contents of the memory addresses are shown as ???????. When properties of the memory window is viewed the Readable and Writeable properties are set as "false". I am not sure whether this is Eclipse issue, or caused by gdb settings. I thought memory properties are gathered through linker scripts.
Has anyone encountered the same problem and find a solution? How to change the eclipse memory window properties, any thought?


ps. I am running Eclipse  with Kepler Service Release 2, Build id. 20140224-0627 on Ubuntu 12.04 environment. Version number of the "arm-none-eabi-gdb" is
