I have an LPCXpresso824 MAX board. I know that it is working as I can run the SDK examples for the UART and of course "blinky".
I am trying to put it into ISP mode and load a file using Flashmagic. With blinky loaded (so I know if user code is running) I hold down SW2 and reset the board before releasing SW2.
This should put the board into ISP mode and I can see that my LED no longer blinks suggesting user code is not running.
I then try to synchronize using Flashmagic (9600 baud) but it times out as "failed to autobaud". I have tried:
1. Both settings for JP3 (board is RevC)
2. Restarting into ISP mode while holding SW2 both with "reset SW3" and by physically disconnecting/reconnecting the USB cable.
I must be missing something, what am I doing wrong?
Hello @scruffmeister
Please make sure connect the correct UART pins. Use PIO0_0 as RXD and PIO0_4 as TXD.
Not the J3 on board.
