LPC11E14 - How to execute program using ISP command

masterboy — Fri, 15 Jul 2016 04:53:04 GMT

Hi all,

I need advice on what is the correct command to start the program via ISP. I tried the "G 0 T" and "G 512 T", but neither command my program does not start.

I tried a program Flash Magic, which is a function to start the program. When I set it up as follows (see figure), program starts ... I have a feeling that the program Flash Magic is doing something other than specified in the UM.

Do you just want to start your freshly loaded firmware? How about to pull reset (if available)?

If the above execution inside Flash Magic is working, have you taken into account, that vector table is used?

Is does not jump to position 0 but look at address 0 (or was it 4? One was Stack Pointer, one was Start Address)

where it shall jump to.

I have a program with which the MCU upload the program (ISP mode). After loading the program I need to make the program started, but can be reset via the MCU pin.

For LPC1114 command "GO 0 T" works, but LPC11E14 not.

Hi Master Boy,

In which address is your reset code loaded? The GO command should point to the reset handler and must be used with an address of 0x0000 0200 or greater.

Thanks in advance for your response!
