MPC5668G: How to execute a function in startup from RAM

[nishan]

Currently all the software(boot, application ) is running from Flash. As part of errata implementation, we want to execute one function in startup(boot) from RAM. What are the changes or steps to be considered for this? This case is when the Flash is corrupted when woke-up from sleep.

Kindly provide your suggestions.

Hi,

in attachment is example, how to place function to RAM (look at the .lcf). In main.c is shown, which pragma you have to use before you can call the function.

Regards,
