Wire error ?

Hello,

In a test program I have set all I / O as output (but also the programming pins...) and know it's impossible to program the LPC11U14. This message is now displayed :

Quote:
02 : Failed on connect: Ee(07). Bad ACK returned from status - wire error.

I have tried to program an other LPC11U14 on a custom board using just the LPC-Link part of the LPCXpresso board. It doesn't work too.

Any idea ?

Thanks

Thomas

Ok thanks, it works for the LPCXpresso board MCU (LPC11U14) but not for the MCU of my custom board (LPC1114 - I have the same message).

It's not the same MCU, so :
- I have linked the SWDIO, SWDCLK, RST and GND of my custom board to the LPC-Link (the custom board is powered by its own 3.3V supply) and disconnected the LPCXpresso board's MCU.
- I have changed the type of MCU in the project's properties.

Anything else to do ?

Thanks !

Thomas

#1 Could you ever debug your custom board so that you are sure your hardware is working?

#2 Did you use FlashMagic to get access to your board?
