Alternativly 🗲FLASH WITH A BROWSER🗲 (Chromium based browsers only).
Thanks go to egzumer for providing this tool.

The rest of this readme is the original from the parent egzumer firmware project.

Open re-implementation of the Quansheng UV-K5/K6/5R v2.1.27 firmware

This repository is a merge of OneOfEleven custom firmware with fagci spectrum analizer plus my few changes.<br> All is a cloned and customized version of DualTachyon's open firmware found here ... a cool achievement !

[!WARNING]
Use this firmware at your own risk (entirely). There is absolutely no guarantee that it will work in any way shape or form on your radio(s), it may even brick your radio(s), in which case, you'd need to buy another radio. Anyway, have fun.

Radio performance

Please note that the Quansheng UV-Kx radios are not professional quality transceivers, their performance is strictly limited. The RX front end has no track-tuned band pass filtering at all, and so are wide band/wide open to any and all signals over a large frequency range.

Using the radio in high intensity RF environments will most likely make reception anything but easy (AM mode will suffer far more than FM ever will), the receiver simply doesn't have a great dynamic range, which results in distorted AM audio with stronger RX'ed signals. There is nothing more anyone can do in firmware/software to improve that, once the RX gain adjustment I do (AM fix) reaches the hardwares limit, your AM RX audio will be all but non-existent (just like Quansheng's firmware). On the other hand, FM RX audio will/should be fine.

But, they are nice toys for the price, fun to play with.

User customization

You can customize the firmware by enabling/disabling various compile options, this allows us to remove certain firmware features in order to make room in the flash for others. You'll find the options at the top of "Makefile" ('0' = disable, '1' = enable) ..

Build optionDescription
🧰 STOCK QUANSHENG FERATURES
ENABLE_UARTwithout this you can't configure radio via PC !
ENABLE_AIRCOPYeasier to just enter frequency with butts
ENABLE_FMRADIOWBFM VHF broadcast band receiver
ENABLE_NOAAeverything NOAA (only of any use in the USA)

ENABLE_TX1750side key 1750Hz TX tone (older style repeater access)
ENABLE_PWRON_PASSWORDpower-on password stuff
ENABLE_DTMF_CALLINGDTMF calling fuctionality, sending calls, receiving calls, group calls, contacts list etc.
ENABLE_FLASHLIGHTenable top flashlight LED (on, blink, SOS)
🧰 CUSTOM MODS
ENABLE_BIG_FREQbig font frequencies (like original QS firmware)
ENABLE_SMALL_BOLDbold channel name/no. (when name + freq channel display mode)
ENABLE_CUSTOM_MENU_LAYOUTchanges how the menu looks like
ENABLE_KEEP_MEM_NAMEmaintain channel name when (re)saving memory channel
ENABLE_WIDE_RXfull 18MHz to 1300MHz RX (though front-end/PA not designed for full range)
ENABLE_TX_WHEN_AMallow TX (always FM) when RX is set to AM
ENABLE_F_CAL_MENUenable the radios hidden frequency calibration menu
ENABLE_CTCSS_TAIL_PHASE_SHIFTstandard CTCSS tail phase shift rather than QS's own 55Hz tone method
ENABLE_BOOT_BEEPSgives user audio feedback on volume knob position at boot-up
ENABLE_SHOW_CHARGE_LEVELshow the charge level when the radio is on charge
ENABLE_REVERSE_BAT_SYMBOLmirror the battery symbol on the status bar (+ pole on the right)
ENABLE_NO_CODE_SCAN_TIMEOUTdisable 32-sec CTCSS/DCS scan timeout (press exit butt instead of time-out to end scan)
ENABLE_AM_FIXdynamically adjust the front end gains when in AM mode to help prevent AM demodulator saturation, ignore the on-screen RSSI level (for now)
ENABLE_AM_FIX_SHOW_DATAshow debug data for the AM fix
ENABLE_SQUELCH_MORE_SENSITIVEmake squelch levels a little bit more sensitive - I plan to let user adjust the values themselves
ENABLE_FASTER_CHANNEL_SCANincreases the channel scan speed, but the squelch is also made more twitchy
ENABLE_RSSI_BARenable a dBm/Sn RSSI bar graph level in place of the little antenna symbols
ENABLE_AUDIO_BARexperimental, display an audio bar level when TX'ing
ENABLE_COPY_CHAN_TO_VFOcopy current channel settings into frequency mode. Long press 1 BAND when in channel mode
ENABLE_SPECTRUMfagci spectrum analyzer, activated with F + 5 NOAA
ENABLE_REDUCE_LOW_MID_TX_POWERmakes medium and low power settings even lower
ENABLE_BYP_RAW_DEMODULATORSadditional BYP (bypass?) and RAW demodulation options, proved not to be very useful, but it is there if you want to experiment
ENABLE_BLMIN_TMP_OFFadditional function for configurable buttons that toggles BLMin on and off wihout saving it to the EEPROM
ENABLE_SCAN_RANGESscan range mode for frequency scanning, see wiki for instructions (radio operation -> frequency scanning)
ENABLE_DOCKEnables the features required for remote operation with Quansheng Dock
🧰 DEBUGGING
ENABLE_AM_FIX_SHOW_DATAdisplays settings used by AM-fix when AM transmission is received
ENABLE_AGC_SHOW_DATAdisplays AGC settings
ENABLE_UART_RW_BK_REGSadds 2 extra commands that allow to read and write BK4819 registers
🧰 COMPILER/LINKER OPTIONS
ENABLE_CLANG**experimental, builds with clang instead of gcc (LTO will be disabled if you enable this)
ENABLE_SWDonly needed if using CPU's SWD port (debugging/programming)
ENABLE_OVERLAYcpu FLASH stuff, not needed
ENABLE_LTOreduces size of compiled firmware but might break EEPROM reads (OVERLAY will be disabled if you enable this)

Compiler

arm-none-eabi GCC version 10.3.1 is recommended, which is the current version on Ubuntu 22.04.03 LTS. Other versions may generate a flash file that is too big. You can get an appropriate version from: https://developer.arm.com/downloads/-/gnu-rm

clang may be used but isn't fully supported. Resulting binaries may also be bigger. You can get it from: https://releases.llvm.org/download.html

Building

Github Codespace build method

This is the least demanding option as you don't have to install enything on your computer. All you need is Github account.

  1. Go to https://github.com/egzumer/uv-k5-firmware-custom
  2. Click green Code button
  3. Change tab from Local to Codespace
  4. Click green Create codespace on main button
<img src="images/codespace1.png" width=700 />
  1. Open Makefile
  2. Edit build options, save Makefile changes
  3. Run ./compile-with-docker.sh in terminal window
  4. Open folder compiled-firmware
  5. Right click firmware.packed.bin
  6. Click Download, now you should have a firmware on your computer that you can proceed to flash on your radio. You can use online flasher
<img src="images/codespace2.png" width=700 />

Docker build method

If you have docker installed you can use compile-with-docker.bat (Windows) or compile-with-docker.sh (Linux/Mac), the output files are created in compiled-firmware folder. This method gives significantly smaller binaries, I've seen differences up to 1kb, so it can fit more functionalities this way. The challenge can be (or not) installing docker itself.

Windows environment build method

  1. Open windows command line and run: 
    winget install -e -h git.git Python.Python.3.8 GnuWin32.Make
winget install -e -h Arm.GnuArmEmbeddedToolchain -v "10 2021.10"
  2. Close command line, open a new one and run: 
    pip install --user --upgrade pip
pip install crcmod
mkdir c:\projects & cd /D c:/projects
git clone https://github.com/egzumer/uv-k5-firmware-custom.git
  3. From now on you can build the firmware by going to c:\projects\uv-k5-firmware-custom and running win_make.bat or by running a command line: 
    cd /D c:\projects\uv-k5-firmware-custom
win_make.bat
  4. To reset the repository and pull new changes run (!!! it will delete all your changes !!!): 
    cd /D c:\projects\uv-k5-firmware-custom
git reset --hard & git clean -fd & git pull

I've left some notes in the win_make.bat file to maybe help with stuff.
