Hi all,
I am using F28M35H52C1 device. I am using CCS5.3.0.0009 . I import a blinky project for ARM. I can able to build the program. Using RAM configuration i can able to debug. If i am using the FLASH configuration i got some memory error. Error is below.
Cortex_M3_0: Loader: One or more sections of your program falls into a memory region that is not writable. These regions will not actually be written to the target. Check your linker configuration and/or memory map.
And my CCS was connected in Debug mode. That time i am try to erase the flash. But i got an error like this:
Target is not connected or does not support to current flash operation.
(This is in TOOL-> On-chip-Flash , Inside option to Erase Flash)
I checked the F28M35x_generic_M3_FLASH.cmd file. My .cmd file is below:
/*
