Exclude address from memory zeroing

JuanL — Wed, 03 Mar 2021 20:22:18 GMT

Hi, I'm using CW 10.2 and MC9S08AW60 with the standard ANSI-C initialization and was wondering if there is any way to exclude certain addresses from the ram zeroin. Say I need to keep the last 3 positions out of the ZeroOut function, is there any way of doing such thing?

Thanks, Juan.-

I am not good in ASM

but I believe that you need to update this function in the start08 file

Hi Vicente, thank you for answering.

Yes, I imagined it had something to do with that function, but could never figure out where or how it's obtaining the number of positions to erase or the starting address (nofZeroOuts / pZeroOut).
