System Memory

SOM-A2558 SDRAM can be configured as 4/8/16/32/64/128/256MB. Users can base on their requirement to reconfigure the SDRAM size.

There are two functions Flash on SOM-A2558 series. One is Boot Flash, the other is Storage Flash.

Boot Flash is 1MB NOR flash. In standard SOM-A2558 series product, Advantech will pre-install the WinCE bootloader in it.

Storage Flash is used to save image & user APs. Storage Flash size is also reconfigurable. The Storage Flash is M-system Flash. Storage Flash size could be 0/16/32/64 MB. SOM-A2558 series have Multiple boot options through the on-board Flash or Compact Flash Card (CFC) for easy maintain and cost saving. If Storage Flash is 0MB that means user should put the image in Compact Flash Card.

CPLD

SOM-A2558 series have one CPLD on board. The CPLD take charges of the following function:

•System memory assignments

•I/O control

•RTC control

Base on Advantech policy, Advantech won’t release the CPLD code to user. In fact, when user designs their own target carrier board, they don’t need to know the CPLD code. Advantech will release memory map of available memory block and available GPIOs. These are fully enough to users to develop their own carrier board.
