LPC9xx/LPC9xxx / LPC932A ISP bootloader entry
August 08, 2007, 06:56:20 AM
Hello,
I know the ISR entry and notouch method has been thoroughly discussed in this forum.
However, I have just one thing to clarify.

From my understanding:
The NoTouch implementation sets the boot status bit and then reset.

Why can't I just jump straight to the bootloader without reset?
I am guessing that it is because the bootloader wants to start with a clean memory space and stack.

So what if my code only checks for the ISP entry condition at the very beginning of the code and then go straight into the bootloader. Is there any problems with that?

thanks!

Eugene
