Tool/software: Code Composer Studio
I am trying to get the shared ram working to share parameters between the C28 and M3 of my concerto device. I have 2 concerto devices, one is the ControlCard development board with a F28M36P63C2 and the other is my target device with a F28M36H33B2, and I am using the RAM_management example code. The code works fine on the F28M36P63C2, but if I program the exact same code on the F28M36H33B2 it does not work. Even if I try to manually edit the array m3_r_w_array, which is placed in the shared ram, in debug mode, the value does not change on either the M3 or the C28. It is as if I don't have access to the Shared RAM, even though it is in SHARERAMS2 which, in this example, the M3 is the Master of. This is the same on the C28 side if I try to access/edit C28_r_w_array on the C28. The 2 devices only differs in flash size, clock speed and some peripherals, the RAM space is exactly the same. Why would the Shared RAM work on the F28M36P63C2 but not the F28M36H33B2? I am using the linker command file in the RAM_management example F28M36x_generic_wshared_M3_RAM.cmd.
