On board JTAG connector[edit | edit source]
JTAG signals are routed to a dedicated connector on the MITO 8M Mini/Nano PCB.
The connector is placed on the top side of the PCB, on the right side (please see the picture below).
J7 - Connector's pinout[edit | edit source]
J7 footprint mates with Samtec FSI-110-03-G-S connector. The following table reports the connector's pinout:
| Pin# | Pin name | Function | Notes |
|---|---|---|---|
| 1 | DGND | - | |
| 2 | EEPROM_WP | - | |
| 3 | NC | - | |
| 4 | JTAG_TCK | - | internal pull-down 10k to DGND |
| 5 | JTAG_TMS | - | |
| 6 | JTAG_TDO | - | |
| 7 | JTAG_TDI | - | |
| 8 | JTAG_nTRST | - | |
| 9 | CPU_PORn | - | internal pull-up 100k to NVCC_SNVS_1V8 |
| 10 | NVCC_3V3 | - | reference voltage for JTAG signals 3.3V |
