Hi,

 

Here is a part of an LDF file which is copied from a refrence ADSP-21487 project:

 

seg_sigma_extdata { TYPE(PM RAM) START (0x000E4DD8) END (0x000E5260) WIDTH (48)}
ss_block7_code { TYPE(SW RAM) START (0x001CF724) END (0x001CF72F) WIDTH (16)}
ss_block8_data { TYPE(DM RAM) START (0x000E7B98) END (0x000E7BA3) WIDTH (32)}

If we want to reduce the length of 'seg_sigma_extdata' and enlarge 'ss_block7_code', how can we caculate new end address of 'seg_sigma_extdata' and start address of 'ss_block7_code'?

 

Thanks.
