I have a new out of the box NGX LPC1857 board. I am using it with LPCXpresso and LPC-Link JTAG board.

I have built the NGX supplied projects, but when I go to flash them I get and error

Failed on connect: Ep(01). Target marked as not debuggable.
Connected. Was: None. DpID:     EDB6. Info: HID64HS12[/color]

The detailed error message is:

crt_emu_lpc18_43_nxp -flash-load-exec "C:\Temp\workspace18\periph_atimer\Debug\periph_atimer.axf" -g -2 -vendor=NXP -

The NGX projects for the 1857 come with the MCU set for 18230. I have tried changing the MCU settings to 1857 but get the same result.

I would appreciate any suggestions or help.

Thanks.
