Cloning, Manual¶
See also
This page details cloning a Mecrisp-Stellaris image from a existing STM32F MCU or Board, complete with the Dictionary, Kernel, your user Words, the init Turnkey Word, … everything.
This reproduces exactly the same bootable system on another STM32F MCU or Board simply by flashing the cloned image to it.
Download the cloning file. It’s named “f051-clone.fs” as I tested it on a STM32F051 Discovery Board.
Download f051-clone.fs
Note
This code is essentialy code by Mattthias Koch found in his Mecrisp-Stellaris distribution in mecrisp-stellaris-x.x.x/lpc1114fn28/hexdump.txt
Set up something to capture the iHex file that will be generated by f051-clone.fs In the example I used the e4thcom terminal and the Unix ‘tee’ command to clone the terminal text into a logfile. You could use Picocom just as easily, or a logfile if your GUI serial terminal application has one.
e4thcom -t mecrisp -d ttyUSB0 -b B115200 | tee e4thcom.log
Load f051-clone.fs onto your chip/board and run ‘clone’, you should see something like this:-
clone
:100000008C030020754800000547000005470000EC
:1000100000000000000000000000000000000000E0
:100020000000000000000000000000002F4700005A
... lots more of the same
:108DF00000000270720000B5FBF72EFAF9F758FC7C
:108E0000043E2E732000F9F7F8FCF9F7EAFB00BDE9
:108E1000FFFFFFFF60080570722E66737047000049
:00000001FF
Remove any log preamble and postamble then save it as clone.hex
Create a binary file from the iHex file
arm-none-eabi-objcopy -I ihex -O binary clone.hex clone.bin
Flash the binary to your STM32F chip/board
st-flash write clone.bin 0x08000000
Test the Clone
Optional; make a MD5SUM of your Clone binary, as it may come in handy later to find the exact same binary.
md5sum clone.bin > clone.bin.md5sum
Finished!
