RAM overlap : Bootloader & user program

rubykrishna — Tue, 09 Jun 2015 06:17:49 GMT

Hi All,

We have two different projects i.e Bootloader and user program . Consider the following sequence on power on reset, .

bootloader startup code ->bootcode->user program start up code->userprogram

Can we use different global variables(global variable 1 : Boot loader & global variable : 2 user program ) which share the same RAM location.

Anyhow, im clearing RAM (start up code ). while jumping to application. there shouldn't be any issues right?

Can we used shared RAM in this case ? Is there any implication ? please help ?
