Other Parts Discussed in Thread: UNIFLASH

Tool/software: Code Composer Studio

Hello,

I want to burn a code in Herculus RM46x MCU. I am using code composer studio. When i run(Debug) a code in the CCS it will remain in the MCU.But when i  unplug the MCU it get erased. How can i burn the code in the MCU so that if i will plug it later it will remain in the MCU. thanks

    If you have your linker map setup to place your code in Flash then CCS will burn the code into flash when you start a debug session. Alternatively you can use the UniFlash tool to do the same. However if you are finding that when you unplug your MCU it is erasing the memory that tells me that your code is not being placed in flash. What does your linker command file look like?

    Someone in the Hercules forum should be able to provide a sample linker command file that places code in flash for this device.

    The code, constants and init are all going into flash. I will ask a device expert to take a look to see if something is missing.
