Hi, I have a system profile structure (set of system properties), saved in a serial dataflash. Size of a profile is about 16K. At power-up I need to extract from this profile another structure - slave profile (6K), and send it to the slave microcontroller over CAN. In order to do that at a certain point I need to initialize both structures in ram. And this is the only time when these structures are used.
The question is - what is the optimum way to allocate memory for these structures ? I am using STM32F107 with 64K of ram. If I initialize structures locally, in a 'parsing / slave initializing' function, I need to assign additional 22K to the stack, and I loose them for the application. By initializing these structures globally I also loose 22K of ram.
Would really appreciate considerations on this subject.
