I ran the FreeRTOS example, and only two LED light up

in
lpcopen_v2_00_lpcxpresso_nxp_lpcxpresso_812.zip

file
board.c

this
static const uint8_t ledBits[] = {7, 17};

should be
static const uint8_t ledBits[] = {7, 16, 17};

and the 220 Ohm resistor  R56 should be ~500 Ohm because it is 2x or 3x brighter than the others.

Thank you for bringing the code example issue to our attention.  We will update the board.c file in the next revision of the LPCOpen library.
R56 could have been specified at a higher value, but the value of R56 is 200 ohms as specified in the Rev. A and B schematics.
