This header has a 'XMOD FTDI JTAG Adapter'-compatible pin-assignment, so the XMOD-FT2232H adapter-board TE0790 can be used in conjunction with the carried board to program the mounted SoM via USB interface.
| JX1 pin | Configured as | B2B |
|---|---|---|
| C (pin 4) | TCK | JB2-100 |
| D (pin 8) | TDO | JB2-98 |
| F (pin 10) | TDI | JB2-96 |
| H (pin 12) | TMS | JB2-94 |
| A (pin 3) | MIO15 | JB1-86 (usable as UART RX/TX-line) |
| B (pin 7) | MIO14 | JB1-91 (usable as UART RX/TX-line) |
Micro SD Card Socket
Micro SD Card socket is not directly wired to the B2B connector pins, but routed through a Texas Instruments TXS02612 SDIO port expander, which is needed for voltage translation due to the different voltage levels of the Micro SD Card and MIO bank 501 of the Xilinx Zynq 7000 chip. The Micro SD Card has 3.3 V signal voltage-level, but the MIO Bank 501 on the Xilinx Zynq 7000 chip is set to 1.8 V.
