I want upgrade 2MB project to 4MB project by uv2 or uv4. Everything seems ok in 2MB project, but when I selected Extended Linker (LX51). Compiler show following error message:
*** ERROR L204: INVALID KEYWORD POS: 4141
How can I do? Thanks.
"*** ERROR L204: INVALID KEYWORD POS: 4141"
That's not a Compiler error - it's from the Linker
Please read the manual: http://www.keil.com/support/man/docs/lx51/lx51_l204.htm
"How can I do?"
It's clearly told you that you've used an invalid Keyword - so don't do that!
Study the Linker Manual to find out what keywords are valid!
Surely, in this day and age, the question should not be how but WHY??
Why on earth - with the ready availability of far better suited chips - would you abuse a poor little 8051 in this way?!
