Announced versus available Flash size on F103
|
|
============================================
|
|
Up to Stlink V2, the CPU soldered on the board was a F103C8 with 64 kiByte
|
|
flash. Up to about version 280 of BMP, this limit was not hit when linked
|
|
against nanolib.
|
|
|
|
StlinkV2-1 has a STM32F103CB, like a genuine BMP.
|
|
|
|
However with more and more devices supported, BMP at about version 282 hit
|
|
this limit. There are two ways to work around:
|
|
- Branch STlink V2-1 as separate platform and and care for the original STlink
|
|
platform by restricting/ommitting features.
|
|
- Rely on uncertain upper flash on F103C8
|
|
|
|
The first option needs more care as an additional platform is introduced and
|
|
will restrict usage of older STlinks as BMPs.
|
|
|
|
However F103C8 and F103CB have the same chip and upper flash exists on F103C8.
|
|
This flash may have been tested bad, or not have been tested at all,
|
|
or, in the best case, was tested good but market requirements made STM sell
|
|
it as F103C8.
|
|
|
|
Ignoring the chip marking and using an F103C8 blindly as a F103CB is done
|
|
already with no known problems on many STM board and china boards (e.g. blue
|
|
pill) with genuine STM32. China stlinks clones with a GD32F103x8 will
|
|
probably not work. Best is to get new genuine ST hardware. The
|
|
STLINK-Vmini is < 10 $ without VAT or to resolder a genuine
|
|
STM32F103CB chip. Think also about using the pc-hosted pc-stlinkv2
|
|
platform on stlinks with revent firmware.
|
|
|
|
Flash above the announced size with recent bootloader/BMP:
|
|
==========================================================
|
|
|
|
Use either the provided python tool, as script/stm32_mem.py
|
|
does not care for the announced size and verifies:
|
|
|
|
> ../scripts/stm32_mem.py blackmagic.bin
|
|
|
|
or compile and use the upgrade executable.
|
|
|
|
> cd upgrade
|
|
> make (PROBE_HOST=...)
|
|
> ./blackmagic_upgrade
|
|
|
|
To long to read
|
|
===============
|
|
Use the BMP provided upgrade tools:
|
|
- scripts/stm32_mem.py
|
|
- Compiled upgrade tool in upgrade
|
|
Only if mismatch is reported, think further.
