Shouldn't SCK and MOSI on JP1 be swaped?

Isn't SCK typically on D13 and MOSI on D11 on Arduino compatible boards? Has anyone tried using an SPI based Arduino shield with this board?

Question relating to:

Seeeduino Arch from Seeed Studio is an mbed enabled development board which combines some advantages of mbed and Arduino. Arch is based on NXP LPC11U24 with Arduino form factor and ...

Next version Arch board will swap P0_9(D13) and P1_29(D11) to be compatible with Arduino Uno.

SPI of Arduino

Mega256051 or ICSP450 or ICSP152 OR ICSP3
LeonardoICSP4ICSP1ICSP3
DueICSP4ICSP1ICSP3

Arduino shields using ICSP connector as SPI are compatible with all kinds of Arduino and Arch.

Thanks.

Are you referring to Seedstudio-Arch board? I compared arduino uno r3 signals to arch board, seems to be not compatible. Can be those pins set to another functionality (multiplexed?). According to their table here: http://www.seeedstudio.com/wiki/Seeeduino_Arch#Compare_Seeeduino_Arch_with_Arduino, the SPI is on that connector SPI which is located in the center on the right side.

Like on KL25Z, they could, MOSI could be MISO. although D13 is just SCK.
