But then it was recorded RAM There is no problem , Should be flash A bit of a problem.

Solution steps

• Create a new project from the process hello_world_mpc5744p, Compile the test and burn it to ram No problem
• from components add to flash_c55, The generated code
• Reference resources MPC5744 Burning has been staying 98% Solutions for
• Add code to led Initialize front , So erase it led It's flashing , We will know that the erasure is complete

  There are three lines of comment code above , from MPC5744 Burning has been staying 98% Solutions for Copying out is an error , It can also be used to comment out the discovery directly
• led Flashing indicates completion , At this time, other projects arrive flash That's fine
