Hi,

What problem can I meet in this process ?
I want use a serwer when for example will be new *.hex file, and that file need to be write to my mcu.
I want use that mcu, becuase there is 2 partitions program memory system, whe for example new program will not

Could You help me step by step what I need to do ?
