DK board application function3.1 CMSIS-DAP interfaceThe QN9080-001-M17 DK board offers the JTAG/SWD interface either to on-board oroff-board QN9080-001-M17 targets. It also provides the USB-to-UART interface forQN9080-001-M17.To change to the CMSIS-DAP interface, see Chapter 4.4 in document UM11097.3.1.1 CMSIS-DAP to on-board QN9080-001-M17When programing or debugging a QN9080-001-M17 device using the CMSIS-DAPinterface, JP1 and JP2 must be configured according to Table 5.Table 5. On-board debugger jumper settingJP1 Open, CMSIS-DAP target is on the QN9080-001-M17 board.JP2 Short pin 1, 2, QN9080-001-M17 power enable.When downloading firmware to QN9080-001-M17 with the ISP mode, enable the UARTpath and set the chip mode pin to ground. The jumper setting is shown in Table 6.Table 6. ISP mode jumper settingJP8 Short, UART path enable.JP15 Short, ISP mode enable.The ISP download operation flow is shown in Fig 13.Fig 13. ISP download operation flowAfter the ISP download operation, remove the jumper cap on jumper JP15 and leave theJP15 open. Then, the QN9080-001-M17 can go into the normal mode normally.3.1.2 CMSIS-DAP to off-board targetWhen using the QN9080-001-M17 DK board to program or debug off-board targets usingthe JTAG/SWD interface, JP1 and JP2 must be configured according to Table 7.Table 7. Off-board jumper settingJP1 Short, CMSIS-DAP target is off-board target.JP2 Short pin 2,3, 3 V power disable on JTAG/SWD connector.3.2 Current consumption testThe QN9080-001-M17 DK board provides two ways to measure the QN9080-001-M17chip current consumption. One way is to measure the current by the on-board preciseresistor used for the I-to-V conversion. The small voltage signal is amplified by theoperation amplifier and fed to the ADC. Then, it can be calculated by LPC4322 andshown in the MCUXpresso IDE. Another way is to measure the current by an externalammeter on jumper JP14.UARTEnableShort ISPJumperISPLoadingPressQN9080-001-M17 RSTButton
