CTRL USE SERIAL JTAG bit in the digital control block selects whether the one wire serial JTAG interface or the alternative six wire parallel JTAG interface is used There are other options in the digital control block which might interest you and our advice is to check the iMX233 s datasheet released by Freescale Page 20 of 44 OLIMEX 2012 OLinuXino User s Manual SJTAG The pin names are also written at the bottom of the board for your convenience 6 1 3 Classic JTAG debug The third option is to use the classic 6 pin parallel JTAG not including GND and VCC There are pads left for this option at the bottom of the board under the SD card holder They are named individually and framed near a JTAG name The important thing is that these pins are multiplexed with the SD card signals In order to use the 6 you will have to stop using the SD card Note also that the classic interface comes without plastic header mounted so in order to use it you will need to use wires for connection Consider the the software settings required to switch from SJTAG to 6 pin JTAG and vice verse referring to the iMX233 manual For instance The HW DIGCTL USE SERIAL bit in the digital control block selects whether the serial JTAG interface or the alternative six wire parallel JTAG interface is used HW DIGCTL CTRL USE SERIAL JTAG 0x0 Selects whether the one wire serial JTAG interface or the alternativ
