Hi ,
we are working for Aerospace domain using the

MC9S12DP256 controller

where we are loading software into flash once and in our code we are performing EEPROM and RAM related operations when fight is in air. at that time Flash corruption is happening. After doing the Root cause analysis what we found was due to code run away problems flash corruption is happening and we added some programs which can initialize the data before writing into flash. But its not exact solution for this problem. So i want to know what could be the reason for flash corruption if the aircraft is in air. How we can avoid them ?
Thanks in advace,
