Hi,
I am having troubles with flashing my first code to the MDBT53V module. I am flashing via JTAG cable, from my nrf52840DK using vscode. According to my measurements the onboard power sourced by npm1300 on my custom pcb is correct. I can also confirm that the MDBT53V VDD pins are properly receiving 1.8V from the npm1300 VOUT1. On jtag footprint, i can also confirm the GND, 1.8V supply is okay. When jtag is not connected there is 1.8V on RESET pin. When i connect the jtag between custom board and nrf52840DK module i measure 2.2V on RESET pin 3 on JTAG footprint of my custom board for some reason. Both SB47 and SB19 is unshorted on the nrf52840DK, according to how I have understood this guide: https://docs.nordicsemi.com/bundle/ug_nrf52840_dk/page/UG/dk/ext_programming_support_P19.html# On the nrf52840DK I have SW9 switch set on VDD, SW 10 on OFF, SW8 ON. 
This is my footprint on pcb:
I have also tried to short the SB19 and supply 1,8V on the VIO REF of nrf52840 from external source and it gave me slightly different error:
I would appreciate any type of insight into my problem.
Thank you in advance.
