Hi All,
I am using Keil uV5.15 version IDE for Cortex M0 controller. In order to calculate the total flash usage I am finding conflicts by seeing: 1. Size in IDE after build "data + RO" in KB 2. Size mention in map file - Total ROM size "data + RO + RW"
Can you please tell which data I should consider and why it is different at different places? As per my understanding, RW is data belongs to RAM. So why it is consider in map file for ROM size calculation?
Thanks in advance!
RAM starts with random/arbitrary content, what you want in it must be copied there every time you restart. Where would the best place to store content that remains the same in the absence of power? ROM perhaps?
