Hi, > Check TI application notes: slaa103
thanks, but that´s only the the way to do Self-Programming, it's not about programming bootloader or updating (of the whole flash) with a Ramloader. That's the reason why i am looking for examples; the flash programming itself is not the problem. > , slaa089A, slaa096B Thanks, but it´s only about the Bootstrap loader and because that requires extra hardware (more than RxD and TxD). Because i can't change the hardware at the customers, i can't use it. Regards Rolf F.
