IMSProg - I2C, MicroWire and SPI EEPROM/Flash chip
Programmer - is a program to read, write EEPROM chips use the
CH341A programmer device.
The IMSProg makes respect to QHexEdit2 hex editor and SNANDer programmer. The format of the chip database is based on the format used in EZP2019, EZP2020, EZP2023, Minpro I, XP866+ programmers. Warning, format is not the same!
IMSProg is a collection of tools:
-
IMSProg - the chip programmer (it's the main part).
-
IMSProg_editor - chip database editor.
-
IMSProg_database_update - script to update chip database using external web-server.
git clone https://github.com/bigbigmdm/IMSProg.git && cd IMSProg
cd IMSProg_programmer
mkdir build
cd build
cmake ..
make -j`nproc`
sudo make install
cd IMSProg_editor
mkdir build
cd build
cmake ..
make -j`nproc`
sudo make install
These commands are included in the build_all.sh file.
For build are needed:
- g++ or clang
- CMake
- libusb 1.0
- Qt5
- Qt5 Qt5LinguistTools
- pkgconf or pkg-config
- udev
On Debian and derivatives:
sudo apt-get install cmake g++ libusb-1.0-0-dev qtbase5-dev qttools5-dev pkgconf
On Debian >=13 and Ubuntu >=23.10:
sudo apt-get install systemd-dev
On older:
sudo apt-get install udev
Optionally if you want to use IMSProg_database_update script:
- zenity
- wget
sudo apt-get install zenity wget
ℹ️ Debian < 11 and Ubuntu < 20.04 are not supported, you may unable to have it working on them.
- Insert the chip into the appropriate slot of the CH341A programmer. The
24xxxand25xxxseries chips must be inserted directly, according to the markings on the PCB of the CH341A programmer. The93xxxseries chips must be inserted into the93xxx adapterand the adapter into the marking25xxxprogrammer slot.
- If the chip supply voltage is 1.8 volt he must be inserted in
1.8 volt adapterand the adapter into needed programmer slot.
- Plug the CH341A programmer into the USB socket of your computer and running
the
IMSProg. - You can plug and unplug the programmer device (CH341A) to the USB port at any time when basic operations (reading, checking, and programming) are not in progress.
- Read more about adapters here.
Select the type of chip used from the Type pop-up menu: SPI FLASH when
using SPI NOR FLASH chips of the 25xxx series, 24_EEPROM when using I2C
EEPROM of the 24xxx series, 93_EEPROM when using MicroWire EEPROM of the
93xxx series.
When using 25xxx series SPI NOR FLASH chips (Menu item type -> SPI_FLASH),
the Detect button will be available. When the Detect button or
or <Ctrl+D> is pressed, the JEDEC information is
read from the chip and all parameters of that chip are loaded from the chip
database. Any parameter (size, page size, block size, VCC voltage,
and 4-bit address length) can be changed manually. You can manually enter
the Manufacture and Name pop-up menu data - all other parameters will be
automatically loaded from the chip database.
When using 24xxx or 93xxx or 95xxx or 25xxx SPI EEPROM (non NOR FLASH)
series chips, it is necessary to manually enter the Manufacture and Name
pop-up menu data - all other parameters will be automatically loaded from the
chip database.
-
Pressing
Reador
or <Ctrl+R>to read data from the chip into the computer buffer. -
Pressing
or <Ctrl+W>to write data from the computer buffer into the chip. -
Pressing
or <Ctrl+E>will erase all data in the chip. -
Pressing the
or <Ctrl+T>button causes the data in the chip and in the computer buffer to be compared.
The progress bar shows the progress of the read, erase, and verify operations.
-
The
Autobutton is used to perform erase, write and verify operations in sequence. If one of these operations is not needed, you can uncheck the checkbox for that operation. -
The
or <Ctrl+I>key is used to force interruption of chip read/write/erase/verify operations. -
The
ikey show the connection chip to CH341A device image form. -
The
Main menu -> Programmer -> Chip infoor<Ctrl+P>item shows the Serial Flash Discoverable Parameter (SFDP) register and the status registers of the SPI NOR flash memory chips.
If the SPI NOR FLASH chip is detected normally, but is not read (gives the
message Error reading sector 0), then in the Chip info window you can
change bits BP4 and BP3 to zero and press the Write registers button.
Then repeat the chip reading operation.
If the SPI NOR FLASH chip is read unreliably (with a different checksum each
time) and Status Register 2 is available in the chip, you can change bits
DRV0 and DRV1 to zero and press the Write Registers button. This will
increase the power of the output stage of the DO pin of the chip. Then
repeat the chip read operation.
For 25xxx, 95xxx series chips that have only one status register, the
Chip info form is as follows:
-
The
or <Ctrl+S>button is used to save the computer buffer to a file. -
The
or <Ctrl+O>button is used to save the file in the computer buffer. -
The
or <Ctrl+Shift-S>button is used to save a part of the computer buffer to a file (the start address and length of the part must be entered). This operation can be used when splitting a binary data image into parts. -
The
or <Ctrl+Shift-S>button is used to load a small file to a certain address in the buffer. The data fragment in the buffer will be replaced with new data from the file. -
The
or <Ctrl+Q>button is used to invoke the chip database editor. -
The menu item
File / Import from Intel HEXis used to save the Intel HEX file in the computer buffer. -
The menu item
File / Export to Intel HEXis used to save the computer buffer to a file in Intel HEX format.
The hexadecimal chip editor (right side of the screen) is used to display and modify buffer data.
It contains the following controls: 
undo,
redo, and the 
search/replace. The [Ctrl+A] key used to update the CRC24 checksum. The
[Ctrl+G] key used to to move the cursor to the entered address.
Chip base editor - IMSProg_editor is a stand-alone program that can be launched
from the Development menu or from the IMSProg program by clicking on
.
All operations in the editor become available only after loading a chip base file with .Dat extension.

The most recent version of the chip database file can be downloaded from this page in both .Dat and .csv formats.
IMSProg_database_update uses the zenity graphical Gnome utility. Once started, it copies the downloaded database to the ~/.local/imsprog folder. The script then displays the number of of chips in the database before and after the upgrade.

The latest version of the chip database can be found here. You can download it and copy it to the ~/.local/imsprog folder:
cp IMSProg.Dat ~/.local/imsprog
-
There is a work in progress for add IMSProg to official
Debian(and derivatives repositories)For some Ubuntu versions you can use this PPA by adding
ppa:bigmdm/imsprogto your system's Software Sources.
sudo add-apt-repository ppa:bigmdm/imsprog
sudo apt update
Is also possible manually build deb package using debian/latest branch.
