Thanks. I'll try that. What I found did work properly was to create a second uninitialized UBYTE buff2[512] array and memcpy the UBYTE buf1[512] initialized array to it, then use buff2 to scsidata. Mike Roth said the compiler will put initialized data in a data hunk and the uninitialized data in a bss hunk, and this was the only difference in the code. Does your cast look like this? : SCSICmd.scsi_Data = ( (UWORD * ) &(UWORD)buffer[0] ); The Lattice / SAS C compiler 5.10 has an __aligned keyword to force alignment. It may really be a linker issue as I could duplicate the problem in assembly (A68k) and Blink using an initialized data array but I haven't tried using a second buffer. I'll let you know what I find out.
