I'd like to connect Lauterbach JTAG debugger to the JTAG connector (J4) on i.MX 8QuadXPlus MEK(MCIMX8QXP-CPU) to debug CA35 software, and I'd like to know the connector type and pin assignment for JTAG signal.

Hello Takashi san,

the pinout of this board is MIPI-10 compatible. You can adapt from the standard 20-pin header to MIPI-10 using the adapter LA-3770.

Product description is here: TRACE32® Converter ARM-20 to MIPI-10/20/34 Arm
