Hi Tom, Because of your layout I think you're using an ADSP 21060. I'm a little bit confused by your memory width of 48 bit. How do you wan't to access it. 32 or 40 Bit would make sense to me. However, if you're using the 21060 with 48 bit data, then your memory attribute for dm_buffer should be DM not PM because it resides in Block 1 and not 0. Hope that helps Christoph -----Ursprgliche Nachricht----- Von: Hanley, Tom [mailto:] Gesendet: Mittwoch, 1. August 2001 23:30 An: Betreff: [adsp] .LDF question.... Hello, I am trying to modify a load description file and am having a slight problem. I am currently using the following for my memory layout: MEMORY { pm_rsti { TYPE(PM RAM) START(0x00020004) END(0x00020007) WIDTH(48) } pm_ep0i { TYPE(PM RAM) START(0x00020040) END(0x00020043) WIDTH(48) } pm_ep1i { TYPE(PM RAM) START(0x00020044) END(0x00020047) WIDTH(48) } pm_code { TYPE(PM RAM) START(0x00020100) END(0x00021fff) WIDTH(48) } dm_buffer{ TYPE(PM RAM) START(0x00030000) END(0x00037fff) WIDTH(48) } pm_prom { TYPE(PM RAM) START(0x00400000) END(0x004fffff) WIDTH(48) } dm_reg { TYPE(DM RAM) START(0x00025000) END(0x00025009) WIDTH(32) } dm_data1 { TYPE(DM RAM) START(0x00980000) END(0x009fffff) WIDTH(32) } } And I am getting and error saying: [Error E1508] The memory 'dm_buffer' has illegal 48 bit address 32767 [Error E1539] The memory layout specified in linker description file is invalid However, according to the header at the the top of the .ldf, 37fff should be a valid 48-bit address. Any ideas why I'm having this problem? is there something else I have to modify in order to allocate memory this way? As alway, thanks :) Tom Hanley _____________________________________ Note: If you do a simple "reply" with your email client, only the author of this message will receive your answer.
