[U-Boot-Users] objcopy

[Charles Krinke]

My apologies. The error when specifying a --gap-fill of either 0x00 or 0xff is
 
File size limit exceeded
 
I have seen this with .section not completely defined, but not with a --gap-fill before and am wondering why the gap fill would cause this.
 
I also have a second question.
 
I can single step through the binary with a BDI2000, but only from the object viewpoint, that is stepi works, but step doesnt. I think there may be an incantation for the assembler to pass a debug flag similar to the -g for the compiler. Something like -Wa,-dwarf (sic). Can someone tell me what the incantation is?
 
Charles

It would be helpful to include the error message.
