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 chip database format is clone with EZP2019, EZP2020, EZP2023, Minpro I, XP866+ programmers. You can edit the database use the EZP Chip data Editor
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
- pkgconf or pkg-config
- udev
On Debian and derivatives:
sudo apt-get install cmake g++ libusb-1.0-0-dev qtbase5-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
24xxx
and25xxx
series chips must be inserted directly, according to the markings on the PCB of the CH341A programmer. The93xxx
series chips must be inserted into the93xxx adapter
and the adapter into the marking25xxx
programmer slot.
- If the chip supply voltage is 1.8 volt he must be inserted in
1.8 volt adapter
and 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.
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
Read
oror
<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 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
Auto
button 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
i
key show the connection chip to CH341A device image form. -
The
Main menu -> Programmer -> Chip info
or<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.
-
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 HEX
is used to save the Intel HEX file in the computer buffer. -
The menu item
File / Export to Intel HEX
is 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.
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.

chipEditor
is finishes. Added chips to the database. - Ver. 1.1.1 - Changing application folders according to Debian policy. Added new language translation.

- Ver. 1.1.6 - SPI erase procedure fixed, deleted unused SPI procedures. Fixed program crash when reading/writing large size chips (25Q256/25Q512). Fixed error diagnostics.
- Ver. 1.1.7 - Fixed building errors.
- Ver. 1.1.8 - Adding support the Intel HEX files format.
- Ver. 1.1.9 - Increased speed of program operation at the moment of chip type change.
- Ver. 1.1.10 - Fixed program crash on chip size mismatch with INTEL hex file size.
- Ver. 1.1.11 - Added support for ASUS CAP files.
- Ver. 1.1.12 - Minor changes to UDEV USB rules.
- Ver. 1.2.1 - The path to the chip database file was changed from /etc/imsprog to /usr/share/imsprog . When updating and editing the chip database, they now work on a copy in the user's home folder (~/.local/share/imsprog). Now there is no need for root permissions to change and update the file. You can use the name of the .bin file as a command line parameter: IMSProg <File.bin>
- Ver. 1.3.1 - Added support 25xx SPI EEPROM chips.
- Ver. 1.3.2 - Bugfix: the hex editor plugin is not resized when the form is resized. Added dynamic polling of the programmer status (connected / not connected).
