EA LPC11U37H Board with ulinkplus debugger in KEIL uVision
The (EA) Embedded Artists OM13074 LPCXpresso LPC11U37 board has been used for tests here. As one can see this board also has another version OM13062 which is sold by NXP and not EA.
In the EA LPC11U37H LPCXpresso Board Schematics I checked that the board is supported by 10-pin, 0.05" SWD connector. The pinout for the SWD connector can be seen in the first page of the blog.
This board is powered by USB and ARM ulink plus is used to program the LPC11U37H via SWD.

As mentioned in my first blog page, not all micro-controllers are supported by KEIL MDK uVision 5. The LPC11U37xx micro-controller family needs the KEIL MDK uVision 4 Legacy Support tool.
- Install the KEIL MDK uVision 4 Legacy Support from KEIL website.
- Download the LPCXpresso LPC11U37 board support files from NXP.
- This board is also supported for the LPCOpen Software Development Platform.
ULINKplus Debugger Settings in KEIL MDK4 Legacy Support
Setup the KEIL MDK4 environment to be interfaced with the ARM ulinkplus debugger.

A maximum of only 4 debug breakpoints are allowed with ulinkplus debugger as mentioned in the data-sheet. I tried to set 6 breakpoints and during runtime 2 breakpoints were automatically disabled as I would have expected it.
The asm and linker must be set in the KEIL MDK4 to point to the complied libraries as shown below.
Blinky Test on the LPCLPC11U37H using ARM ulinkplus
After the debugger settings are done. Now we are ready to flash the blinky code on the LPC11U37H LPCXpresso Board.
