SoC and Debug pinouts

CC2630

To program or read-out this tag you have two options:

  • Connect BL pin to GND and power on (or reset if already powered on) to enter bootloader mode, then use cc2538-bsl to flash firmware via UART.
  • cJTAG or JTAG programmer (J-Link or TI's XDS110), you need to solder the debug pins from the SOC, which is pretty hard for most people.
