Ciao Jonathan,
OpenOCD runs binary code on the target CPU to speed-up some operation
that through JTAG would take too long.
Programming the Flash is one of them.
In the CFI driver there is the binary code for generic ARM only.
armv4_5_info.common_magic = ARM_COMMON_MAGIC;
STM32 is a Cortex M3 CPU, and it requires code to be labelled
"ARMV7M_COMMON_MAGIC" to run it. This is why you get that error.
At this point I already see something to double check in the code:
Cortex M3 code defines the macro CORTEX_M3_COMMON_MAGIC, but then
requires ARMV7M....
What you found is a missing feature of OpenOCD.
The fix would require one of the following:
- a specific code for ARMV7M (this will solve your case only)
- a fall-back C code in case of no binary for target (solves all
cases, but slow)
This has been on my todo list for a while.
A temp workaround is to not use a working area - it will be a lot slower
however.
My init script for the stm32 fsmc can be found here:
