Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

Hi guys,

I'm having an issue flashing my PM3 from Gezhi Eletronic co. on VirtualBox Linux kali 5.4.0-kali4-amd64 #1 SMP Debian 5.4.19-1kali1 (2020-02-17) x86_64 GNU/Linux. I followed the extract steps from github installation guide below but faced issues.

https://github.com/RfidResearchGroup/pr … uctions.md produces Linux-Installation-Instructions.

I have search around forums and try many solution but still unable to do so I am posting this and hope someone can help me.

Kali linux USB detected Proxmark

Look like proxmark tool unable detect ttyACM0 However, in "sudo dmesg | grep -i usb" shown it was there.

Any one can help with this. I will really appreciate it.

Re: Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

Good evening, tried with it,
cd proxmark3
: ~ / proxmark3 $ ./pm3-flash-all # there is no need to press the button, it switches to flash mode by itself.
Good evening

Re: Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

Hi Fazer,

I have tried with or without press the button as the result shown above. I am still unable to flash it. I am not really sure what is the issue that I really facing to.

Re: Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

Your flash failed, 
Did you compile the repo for non-rdv4 / aka generic pm3?

Re: Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

Yes, it worked after I tried following steps to compile with non-rdv4.

Created the following Makefile.platform

cat Makefile.platform

# Run 'make PLATFORM=' to get an exhaustive list of possible parameters for this file.

#PLATFORM=PM3RDV4

However, I received several error when Validating proxmark client functionality and it could due to the LF antenna issue ? So I tried to re-run the flashing again but it happen the same thing like my first post. I am wondering is my initial successful flashing is not completely and make the tool unable to identify the access card.

Re: Unable to Flash on ttyACM0 (PM3 from Gezhi Eletronic)

your usb speed is very slow.   Check your cable and usb port.

Transfer Speed PM3 -> Client = 103424 bytes/s
