Overview

stc8prog - STC MCU ISP flash tool

stc8prog is a command line flash programming tool for STC 8051 series microcontrollers, Currently, only STC8H/STC8G/STC8A8K64D4, STC15 (FWVER > 0x72) series are supported.

STC microcontrollers have an UART/USB based boot strap loader (BSL). It utilizes a packet-based protocol to flash the code memory and IAP memory over a serial link. This is referred to as in-system programming (ISP). This tool is built according to the ISP described in STC8H datasheet.

Tested MCU Types:

STC8A8K64S4A12
STC8A8K64D4
STC8G1K08A
STC8H1K08
STC8H3K32S2
STC8H3K64S4

How To Use

CLI Tool

Usage: stc8prog [options]...
  -h, --help            display this message
  -p, --port <device>   set device path
  -s, --speed <baud>    set download baudrate
  -f, --flash <file>    flash chip with data from hex file
  -e, --erase           erase the entire chip
  -d, --debug           enable debug output
  -v, --version         display version information

Baudrate options: 
   4800, 9600, 19200, 38400, 57600, 115200, 230400, 460800, 500000, 576000,
   921600, 1000000, 1152000, 1500000, 2000000, 2500000, 3000000, 3500000,
   4000000

Check

Communicate with MCU without changing anything. It will communicate in 2400 baud first, then switch to a higher baud for a second check

# 2400 baud -> 115200 baud
./stc8prog -p /dev/ttyUSB0

You can specify other baud with parameter -s

# 2400 baud -> 1152000 baud
./stc8prog -p /dev/ttyUSB0 -s 1152000

Erase Flash

This will erase the flash.

./stc8prog -p /dev/ttyUSB0 -e

Write Flash

Suggest to erase before writing flash

./stc8prog -p /dev/ttyUSB0 -e -f foo.hex

High baudrate will speed up the writing

./stc8prog -p /dev/ttyUSB0 -s 1152000 -e -f foo.hex

PlatformIO Integration

1. Add it to packages

By default PlatformIO places packages at /home/[username]/.platformio/packages, create a folder named tool-stc8prog under it, and place stc8prog executable under it.

2. Configurate platformio.ini

Create a new env in platformio.ini, it can be a clone of existing one, change the name and change upload_protocol option to custom, then configurate the rest accordingly, for example:

[env:stc8h3k32s2-stc8prog]
platform = intel_mcs51
board = stc8h3k32s2
upload_protocol = custom
upload_port = /dev/ttyUSB0
upload_flags =
    -p
    $UPLOAD_PORT
    -s
    1152000
    -e
upload_command = ${platformio.packages_dir}/tool-stc8prog/stc8prog $UPLOAD_FLAGS -f $SOURCE

If you want to make this env default, set it to default_envs

[platformio]
default_envs = stc8h3k32s2-stc8prog

For more options, please read platformio section_env_upload

3. First time upload

You can trigger upload with hotkey Ctrl+Alt+U.

If there are any erros and you want to see more detailed logs, run it in the verbose way:

Click PlatformIO icon in the left navigation panel
Expand [your env name] in PROJECT TASKS
Expand Advanced
Click Verbose Upload, this will output the full log of all commands

Build From Source

Install DEV-tools

sudo apt install build-essential

Checkout the project

git clone https://github.com/IOsetting/stc8prog.git

Compile the project

cd stc8prog
make

Comments

feat: extension of the --reset option to alternatively accept an exte…

…rnal command to reset or power cycle the MCU

The --reset option alternatively accepts an external command, which resets or power cycles the MCU, e.g.:

stc8prog -p /dev/ttyUSB0 -r tools/koradctl /dev/ttyACM3 off-on \; -e -f obj/ledtest.ihx
Loading hex file:    Loaded 363 bytes between: 0000 to 0171
Opening port /dev/ttyUSB0: done
Running reset command and waiting for MCU: detected
MCU type: STC8G1K08A-8PIN
Protocol: STC8G/8H
F/W version: 7.3.12U
IRC frequency(Hz): unadjusted
Switching to 115200 baud, chip: set, host: set, ping: succ
Erasing chip: succ
Writing flash, size 370: 100.00% done

The command must be terminated with a semicolon.

For the above example I used a STC8G1K08A 8pin MCU on a breadboard powered by a Korad KD3005P lab power supply. The command "koradctl" is a very simple Python program:

#!/usr/bin/python3
# Very simple control script for Korad KD3005P Lab Power Supply

import argparse
import serial
import time

commands = ('ident', 'on', 'off', 'off-on')

parser = argparse.ArgumentParser()
parser.add_argument("port", help="serial device, e.g. /dev/ttyACM0")
parser.add_argument("command", choices=commands, help="command to execute")
args = parser.parse_args()

with serial.Serial(args.port, timeout=1) as port:
    if args.command == 'ident':
        port.write(b'*IDN?')
        print(port.read(30).decode('ascii'))
    elif args.command == 'on':
        port.write(b'OUT1')
    elif args.command == 'off':
        port.write(b'OUT0')
    elif args.command == 'off-on':
        port.write(b'OUT0')
        time.sleep(1)
        port.write(b'OUT1')

The new feature has only been tested on Linux.

STC8G1K08A-8PIN 7.3.12U on MacOS: doesn't flash

Even though macOS isn't supported, I was able to compile the binary using Linux termios.c dep.

Testing on STC8G1K08A-8PIN was initially promising:

./stc8prog -p /dev/cu.usbserial-1440

However, upon trying to flash an actual firmware, I stumbled upon this issue where the MCU just won't reply back:

./stc8prog -p /dev/cu.usbserial-1440 -d -f ../projects/blink/test.hex

Additionally I tested the erase feature, which actually worked. I flashed a simple blinky via STC-ISP and after erasing it stopped executing, so I assume it actually erased the flash contents:

I know it was never stated that this was supposed to work on macOS, but maybe it's not something macOS related or the problem is something really simple that we can easily fix. I can assist from my side in case you need any further details or help. Thanks!

EDIT: I've also tried using different baudrates from 300 up to 115200, didn't help.

build on macOS

The project builds perfectly with Linux termios serial dependency, however macOS' headers lack some of the predefined baudrates which I had to redefine in termios.c. Amended Makefile to make it aware of Darwin target OS. Added build instructions in README.md

Tested on latest macOS 12.6 and STC8G1K08A-8PIN

Windows support

Now stc8prog could be compiled in Windows under Cygwin to work under Windows environment.

For more reliable firmware uploading while reset option is applied, mcu resetting could be performed up to 3 times if no mcu has been detected in a given time.

Project structure has changed - added folders with source.

Changed Makefile to use system environment variables.

feat(reset): add possibility to reset the MCU before flashing by pull…

Most of usb-uart converters have dtr pin. It's can be used to reset the MCU before flashing to remove unnecessary physical operations. To make reset by dtr flag 'r' added.

[Windows]Opening port COM16: can not open port
I compiled stc8prog with Cygwin64 but the software can not open the COM port on Windows. I tried both way and it doesn't work. The MinGW version that I managed to compile also doesn't connect.

Tested on ARM-DAPLink and a genuine FT2232. Both of them don't work.
