3.2 Connectors description

3.2.1
NXP i.MX8M processors offer many different SDIO interfaces, that can be used independently one from the other to implement different mass storages media (internal
eMMC, internal SD Card, external SDI/O interface).
The μSD card slot CN5 on this module is soldered on top side of the module and realized through Alcor Micro AU6465R for data transmission between USB and
card interface. In this case, USBP4 host port 2.0 is not available as an external interface on Q7 card edge connector.
Please be aware that the μSD card slot is a flip-top type: this means that, in order to insert / extract / change a μSD card, the
heatsink/heatspreader must not be mounted, otherwise it will be impossible to access/open the flip top slot.
3.2.2 JTAG connector
NXP i.MX8M processors have a system JTAG Controller (SJC) and support two JTAG modes, debug mode and test mode. This interface is accessible through
connector CN6, type JST p/n SM07B-SRSS-TB with the following pinout. Please refer to NXP i.MX8M development reference manual for correct implementation.
