Hi everyone
I m sorry if i m writing in the wrong place.
I m following the course about Schematic & PCB Design, I have i simple question about JTAG signals on the base board. On iMX53 datasheet theare are signals for handling JTAG protocol but I saw in the course schematic of the base board that there are no JTAG signals outgoing from SODIMM slot (page 1) throut the JTAG header connectors.
There are 2 JTAG headers (page 8) connected togather only, without a connection to the SODIMM slot and so without a connection to the iMX53 module.
Why this configuration without a JTAG connection to the CPU? have I made a mistake?
thank you in advance
Rocco

There are JTAG pads on the bottom of the module and when module is plugged in these pads will connect to special connector on baseboard. You can see it on the pictures:

Thank you
Now this have more sense, I did not found a schematic for the IMX53 DIMM module in the voipac site.
best regards
