Problem pm5_power_idle()'s WFI sleep adds ~40-50ms of latency before the main loop notices a fresh byte on CEP's SPI1/USART1. At idle this is the whole point of WFI - but it's also what made the original attach handshake miss bytes (GH #3667): cep_attach_poll() runs every 50ms, and WFI's own latency on top of that was enough to lose bytes of the Flipper's one-shot handshake string often enough to require a physical cable replug to recover. Change armsrc/appmain.c: skip pm5_power_idle() entirely once cep_is_attached() is true, so the main loop polls CEP as fast as the hardware allows for as long as a Flipper is physically present. armsrc/pm5_cep.c/.h: new cep_is_attached(), true as soon as the CC controller reports a physical attach - independent of whether the handshake/SPI transport is actually up yet, so the loop stops sleeping before the handshake even starts, not after. Paired with a CEP_ACTIVITY_TIMEOUT_MS (3000ms) idle-detach: the FAP quitting doesn't touch the CC controller's attach bit (the cable stays connected), so losing its normal 20-120ms SPI poll cadence for this long is what actually means it's gone - at that point cep_is_attached() still reflects the physical attach correctly, but cep_is_active() (and therefore this PR's WFI-skip, which gates on attachment rather than a completed handshake) only backs off once the FAP itself has clearly quit rather than just being between polls. Built on top of the AT32 SPI1 errata fix (bounded waits + resync) from the companion CEP-reliability PR - running the main loop flat-out against an unbounded wait would have just hit that hang faster, which is why this shipped after rather than alongside it. Behaviour change PM5 no longer downclocks to WFI between main-loop iterations while a Flipper is attached over CEP (idle power draw increases for the duration of the attach; unaffected when no Flipper is present, and unaffected on RDV4/non-CEP builds). Testing - make clean && make PLATFORM=PM5 PLATFORM_EXTRAS=BWM and make clean && make PLATFORM=PM3RDV4 - both zero warnings. - Hardware: this flag was active throughout all of the companion CEP- reliability PR's hardware testing (60s/110s/240s captures, 18x `hw status`, 5x attach/detach + `hf search` cycles against a real card) - all passed with WFI-skip engaged the whole time. Additionally reflashed this exact branch standalone and reconfirmed a live attach/detach cycle completes cleanly. - Not tested: clang toolchain (firmware-only diff); idle power draw was not independently measured (no direct ammeter in this session's bench setup, only observed BWM telemetry prior to this change). Checklist - [x] Proper style of own code, no unrelated reformatting included - [x] Builds warning-free with gcc (PM5 and RDV4) - [ ] clang not tried (firmware-only diff) Co-Authored-By: Claude Sonnet 5 <noreply@anthropic.com>
Iceman Fork - Proxmark
The Proxmark is the swiss-army tool of RFID, allowing for interactions with the vast majority of RFID tags on a global scale. Originally built by Jonathan Westhues, the device is now the goto tool for RFID Analysis for the enthusiast.
Iceman repository is considered to be the pinnacle of features and functionality, enabling a huge range of extremely useful and convenient commands and Python/LUA scripts to automate chip identification, penetration testing, and programming.

How to build?
Proxmark5
The last hardware generation is called Proxmark5. It has
- MCU: AT32F435, a 288 MHz Artery Cortex-M4
- Gowin FPGA
- TypeC Extended Port (CEP)
- BLE / Wifi / Battery Addon, via a ESp32c2
- Swappable antennas (LF, HF, UHF)
- 125, 134, 250, 375, 500 KHz Low Frequency Antenna (LF)
- 13.56 MHz High Frequency Antenna (HF)
- as a addon: 860-960 MHz Ultra High Frequency Antenna (UHF), ** not developed yet **
At the moment, Proxmark5-specific instructions are all grouped in a single Getting Started guide. Read it to build, flash and run your Proxmark5 device. See the instruction links in the tables above to get the compilation environment.
- ⚠ The firmware is not stable at the moment and is actively being developed at.
- ⚠ Don't install the BWM addon board for now.
Proxmark3 RDV4
See the instruction links in the tables above to build, flash and run for your Proxmark3 RDV4 device.
Generic Proxmark3 platforms
In order to build this repo for generic Proxmark3 platforms we urge you to read Advanced compilation parameters
We define generic Proxmark3 platforms as following devices.
Supported
- RDV1, RDV2, RDV3 easy
- Ryscorp green PCB version
- Radiowar black PCB version
- numerous Chinese adapted versions of the RDV3 easy (kkmoon, PiSwords etc)
- Proxmark3 SE (Special Edition) (BLE enabled)
- Proxmark3 X
- Note: Community tested
- Note: unknown device hw
- iCopy-X
- Note: Compatible ONLY after installation of iCopy-X Open Source firmware
- Factory firmware is not compatible (Client Commands are different / Factory UI closed source / Factory Firmware enforces tag DRM)
Not supported
- ⚠ Proxmark Evolution (EVO)
- Note: unknown pin assignments.
- ⚠ Ryscorp Proxmark3 Pro
- Note: device has different fpga and unknown pin assignments.
- Note: Company have disappeared, leaving their customers in the dark.
Experimental support
- ⚠ Proxmark3 Ultimate
- Note: unknown device hw
- Note: FPGA images is building for it. Use on your own risk.
Unknown support status
- ⚠ VX
- Note: unknown device hw
When it comes to these new unknown models we are depending on the community to report in if this repo works and what they did to make it work.
256KB flash memory size of generic Proxmark3 platforms
⚠ Note: You need to keep a eye on how large your ARM chip built-in flash memory is. With 512KB you are fine but if its 256KB you need to compile this repo with even less functionality. When running the
./pm3-flash-allyou can see which size your device have if you have the bootloader from this repo installed. Otherwise you will find the size reported in the start message when running the Proxmark3 client./pm3.
What has changed?
See the Changelog file which we try to keep updated.
Development
⚠ Note: This is a bleeding edge repository. The maintainers actively is working out of this repository and will be periodically re-structuring the code to make it easier to comprehend, navigate, build, test, and contribute to, so DO expect significant changes to code layout on a regular basis.
👉 Remember! If you intend to contribute to the code, please read the coding style notes first. We usually merge your contributions fast since we do like the idea of getting a functionality in the Proxmark3 and weed out the bugs afterwards.
The public roadmap is an excellent start to read if you are interesting in contributing.
Supported operating systems
This repo compiles nicely on
- WSL1 on Windows 10
- WSL2 on Windows 10/11
- Proxspace environment release v3.xx
- Windows/MinGW environment
- Ubuntu, ParrotOS, Gentoo, Pentoo, Kali, NetHunter, Arch Linux, Fedora, Debian, Raspbian
- Android / Termux
- macOS / Homebrew (or MacPorts, experimental) / Apple Silicon M1
- iOS (Jailbroken, rootful)
- Docker container
Precompiled binaries

Proxmark3 GUI
Most community driven GUI for Proxmark tends to be quite old and out-of-date. Here is a list of a few:
- Proxmark3 Universal GUI will work more or less.
- Proxmark3 GUI cross-compiled which is recently updated and claims to support latest source of this repo.
- Proxmark3_GUI simple gui in vb.net
