MIPI10 STDC14 pin CN9 Designation
- 13 T_VCP_RX Target RX used for VCP (UART supporting bootloader)
- 14 T_VCP_TX Target TX used for VCP (UART supporting bootloader)
TAG connector
The CN10 TAG connector is implemented on the B-U585I-IOT02A Discovery kit. The TAG connector is a 10‑pin
footprint supporting SWD mode, which is shared with the same signals as the ST-LINK. The TC2050-IDC-NL
cable is the recommended one to link ST-LINK and TAG connectors on the B-U585I-IOT02A Discovery kit so that
the MCU can be easily programmed and debugged without any extra accessories.
