Perfect!

This one is the easiest

I will assume the following ...

• MMU is enabled
• YFNX is mapped somewhere
• RM32 is mapped at page 9
• WW Container will be mapped to page 10
• active WW Container will be at RAM address 830 (based on your previous message)
• saved WW Container is at Flash address 1FE (based on your previous message)
  

The update procedure ...

Code:

command                     description

Code:

"EMPT A"                    remove whatever is at page 10 (assumed WW Container)
PPLUG                       unmap page 10
"1FE>830"                   saved WW Container address in Flash and destination WW Container address in RAM
YMCPY                       copy WW Container from Flash to RAM
"-830 A"                    WW Container address in RAM and where to mapped it
PPLUG                       do the mapping

Yep! Have fun ...
