Iceman1001/proxmark3 RDV2 Antenna(s) are UNUSABLE

Hello forum,

Please accept my apologies if the formatting of this question is incorrect for I am a n00b, I have lurked around these forums for a while now and have come across a problem that I've been unable to solve and hope that the community will be kind enough to help me:

I have an issue where

hw tune

results in:

[!] LF antenna is UNUSABLE 
          
[!] HF antenna is UNUSABLE          
          
[-] Not showing LF tuning graph since all values is zero.

I've got a (new out of the box) RDV2 and updated the bootloader and fullimage using:

user@user:~/proxmark3/proxmark3$ client/flasher /dev/ttyACM0 -b bootrom/obj/bootrom.elf armsrc/obj/fullimage.elf

i have compiled the cloned git using:

make clean && make all

which completes without error.

I am able to flash the bootloader.elf and fullimage.elf by keeping the button held (for the duration of the flash) whilst connecting the PM3.

The flash procedure completes like this:

user@user:~/proxmark3/proxmark3$ client/flasher /dev/ttyACM0 -b bootrom/obj/bootrom.elf armsrc/obj/fullimage.elf

For what it is worth, I have read through ubuntu install instructions and uninstalled modemmanager, I'm on ubuntu 18.04.3 and have corrected permissions for /dev/ttyACM0:

user@user:~/proxmark3/proxmark3$ [ -r /dev/ttyACM0 ] && [ -w /dev/ttyACM0 ] && echo ok
ok

Please help! smile

Re: Iceman1001/proxmark3 RDV2 Antenna(s) are UNUSABLE

....  try  RRG/Iceman repo  compiled with PM3OTHER  and see what happens.

Re: Iceman1001/proxmark3 RDV2 Antenna(s) are UNUSABLE

Hi Iceman/forum,

Thanks for the reply, could you expand a little on what you mean by 'compiled with PM3OTHER' and how to do this?

I've have also tried using the RRG/iceman repo but only using the same make clean && make all compile commands.

Is there a way to build this specifically for an RDV2?

Re: Iceman1001/proxmark3 RDV2 Antenna(s) are UNUSABLE

Yes,  since be default it targets PM3RDV4 devices when compiling but is easliy adapted to always target non-rdv4,  ie  PM3OTHER

This makes sense to me, thanks. I will give it a try and report back.

Hi iceman/forum,

I have compiled the RRG/Iceman repo and used the 'PM3OTHER' option which no shows voltage but is unable to locate any LF tags:

I've even tried applying 3.3v to pin 55 on the at91 and still see the same results.

Is there anything else that I can try?

Thanks

Re: Iceman1001/proxmark3 RDV2 Antenna(s) are UNUSABLE

Your LF voltages is crap.  Have you connected the hf/lf antennas to the right ports on your RDV2?

and run
