Why the address offset a byte and two bytes are written to memory on dsp c2812 processor.

chao jia

I run a c2812 testcase and disassembly it and find that address offset a byte and two bytes are written to memory .

this is why ? can you help me to explain it ? the red follows is the physical address ?

0x00000000   __edata, edata, __data, .data
0x00000000   0x60C4   0x003F   0xFFFF   0x0000   0x0000   0x0000   0x6057   0x003F   0x0000

Which emulor are you using with your C2000 board? If it is a JTAG Jet emulator, please see this thread which looks to be related to the issue you are seeing.

I have not heard of such an issue with the simulator. Which version of CCS are you using?
The F2812 simulator has not been supported for a while unfortunately, so you may want to consider updating your tools and/or purcashing a development kit so you can debug with an emulator rather than the simulator.
