I tried the example code for deep sleep mode on the coineltech LPC1788 header board, but the current consumption is not going as low as I expected.
The toolchain I used is crossstudio from Rowley.

In the datasheet I found for deep sleep mode IDD(REG)(3V3) = 550  µA,

My measurement of the current flowing into the board is always around 40 mA, no matter if running while(1); or entering a sleep/power mode.

Any hints?
