Hello everyone,

I work on a project where I have to constantly reprogram my 8051. The board that I am working on is a fully equipped board with memory, serial ports and etc. A co-worker of mines suggested that I should build a bootloader program. I think it works in the following manner:

PC connects to micro via serial port
Micro contains a simple program to receive certain instructions from PC and write them to memory
User on the PC selects which program to run
Micro reads program selection out of memory and executes it

Has anybody done something like this or has any suggestions? It does sound too difficult and makes sense for me. The only confusion I have is whether I should be sending the micro the assembly code or the hex code.

Thanks,

Thomas
