Hi, I am a student. I have to write very important program in µV2 Keil , but I have not so much skills in programming and have some problems. I think that you have much skills in this case and can help me. I use ST10F168. I must reprogram several times Flash via CAN. Are there any possibilities to write such a program? possible solutions ST10F168: 1. Is it possible to do bootload via CAN? 2. At first bootload via seriall interface and then an update via CAN. There is a part of Flash for CANloader.c, which must be saved, you are not allowed to delet or rewrite this part of program. The other part of Flash is for main.c routine, this part can be rewrited(reprogrammed). Other µC ST10F269 or ST10F276: 3. If it is impossible to solve these tasks, than is there any possibilities to use it with ST10F269 or ST10F276. If anyone have some ideas, how I can solve this question, then answer me please. It would be also perfect, if zou could show me some examples of such aplications. I need realy your help. Thanks and best Regards for your answer
