6.3 EDK, PlatGen - OPB_EMC - "ERROR:MDT - opb_emc (SRAM_256Kx32) - C:\system.mhs:194 - address space is less than min_size 512 bytes!"

描述

Keywords: EDK, XPS, PlatGen, BSB, EMC, OPB_EMC, Address

Urgency: Standard

General Description:
In EDK 6.2, the BSB created designs which included the OPB_EMC v1.10.b core. When these designs are run through EDK 6.3, PlatGen will issue the following DRC error:

"Check platform address map ...
ERROR:MDT - opb_emc (SRAM_256Kx32) - C:\junk\gmm9\_xmk_sv\system.mhs:194 -
address space is less than min_size 512 bytes!"

解决方案

In the MHS file, the parameters are available on the OPB_EMC core:

PARAMETER C_BASEADDR = 0x80200200
PARAMETER C_HIGHADDR = 0x8020021f

Notice, the address space is 0x1F here, which is a range of 32 bytes. This is less than 512 bytes and as such causes the DRC error.

To resolve this error, change the HIGHADDR to 0x802003ff or a memory range greater than 512 bytes.
