NCS v2.7.0 radio_test example for nrf5340 toggle_dcdc_state

Question

Greetings, 
 Is the command toggle_dcdc_state supported in the radio_test sample when compiled for the nRF5340? ( https://docs.nordicsemi.com/bundle/ncs-latest/page/nrf/samples/peripheral/radio_test/README.html#user_interface ) 
 I see an error when I try to use it: 
 radio_test:~$ toggle_dcdc_state toggle_dcdc_state: command not found radio_test:~$ 
 If it is not supported, what is the default state of the DC/DC converter? 
 Thanks, 
 Bob

NCS 2.7 and 53 + the radio test does not seem to work as intended so will have to fix that. But, for disabling DCDC, use the nrfjprog command and write to memory. So you can use the following: nrfjprog --memrd 0x50004B00 nrfjprog --memwr 0x50004B00 --val 0 Set the --val <X> ot 0 or 1, where 1 is enabled and 0 is disabled. You can see all the adresses here: https://docs.nordicsemi.com/bundle/ps_nrf5340/page/regulators.html#ariaid-title10 , and this shows the base adress: https://docs.nordicsemi.com/bundle/ps_nrf5340/page/regulators.html#d1610e233 So base address is 0x50004000 or 0x40004000 depending on if you are ins secure ot non secure domain. DC/DC enable register for VREGMAIN = 0x704 DC/DC enable register for VREGRADIO = 0x904 DC/DC enable register for VREGH = 0xB00 This way you can test without having to rebuild the application Regards, Jonathan
