Comment(by dsd):

 I think that is closer but not quite matching what the docs say. How about

 : setup-header-end  ( -- endbyte )   load-base h# 201 + c@ h# 202 + ;
 : setup-header-size ( -- #bytes ) setup-header-end h# 1f1 - 1+ ;

 0 +lp  d# 4096 erase
 load-base h# 1f1 + h# 1f1 +lp  setup-header-size  move   \ Copy the 16-bit

 Then remove all the erase statements from set-parameters.

 I have gone all the way back to 2008 and the protocol has not changed, so
 this should be safe to apply for all kernels.

 I'm not sure if any change is also needed to this line as I can't figure
 out what "/string" does:
    loaded code16-size /string  linux-base  swap  move  \ Copy the 32-bit

 If you build a firmware I am happy to test. It can wait until you are back
 at home of course.
