#93056 - what i want, Dan Responding to: ???'s previous message |
Hi dan,
I need to convert a Hex file to scrambled format and at the mcu back to the real data to be placed on the right adress inside the flash. I does not need to be Intel hex format. One can also implement such a protcol which does: 1- convert it back to hex format, but the adress and data scrambled 2-once inside the mcu, the mcu's encryption algorithm converts it back to the original data and the correct adresses and then it should work as normal. No that i can implement TEA encryption in the 8051, i am going to work on a program which can communicate with 8051 mcu and which implements the protocol for flashing the mcu. Best regards, Khaled |
