The JTAG-interface of the mounted 4 x 5 SoM can be accessed via header JX1. This header has a 'XMOD FTDI JTAG Adapter'-compatible pin-assignment:
JX1 pin | JX1 pin net-name | B2B |
---|---|---|
C (pin 4) | TCK | JB3-100 |
D (pin 8) | TDO | JB3-98 |
F (pin 10) | TDI | JB3-96 |
H (pin 12) | TMS | JB3-94 |
A (pin 3) | MIO15 | JB1-86 (usable as UART RX/TX-line) |
B (pin 7) | MIO14 | JB1-91 (usable as UART RX/TX-line) |
E (pin 9) | BOOTMODE | JB1-90 (JTAGSELECT) |
G (pin 11) | RESIN | JB3-17 |
