i think you can do what you want with a uC that supports ISP or IAP, but you would have to load the program in the FLASH. Not just flash; some MCUs allow loading the program into RAM too. Those ST Microelectronics derivatives I spoke of, in addition to having dual on-chip flash memories, have up to 32K of MCU-resident SRAM that can be used for XDATA or code. Switching which memory to fetch instructions from can be done on-the-fly using the PAGE and VM registers. If you've got factory or field test, (re)calibration, etc. functions to perform, you can just load 'em into RAM without having to displace production code in flash. |
