I use the FPP mode (Msel=000) and configuration is not being loaded when measuring. > Do you have any programming/JTAG pin floating when the device is unconfigured? I have a JTAG test board (with USB blaster programming access) interfacing to a connector on my board. If this test board is not connected, TDI, TCK and TMS are floating. However, the current is not different in both modes. In meantime I found out that I have fixed TRST at 2.5V (high) where VCCPGM is at 3.3V, but I don't think this may cause such high current. Do you have different opinion? > Even if you don't have any shunt resistors on the power rails... Actually I've got 0-Ohm bridges after the inductors which I may lift off for current measurement. This may serve as a starting point to an experiment of lifting of one after another connected device to find the "guilty guy". Right now, I just hoped that there might be non- or minimal-invasive methods, as those boards have a 4-digit BOM... Anyway, which power consumption (core, I/O) would you prior to programming such a device (right now found no numbers in the DC parameters)?
