SW4STM32 and SW4Linux fully supports the STM32MP1 asymmetric multicore Cortex/A7+M4 MPUs

   With System Workbench for Linux, Embedded Linux on the STM32MP1 family of MPUs from ST was never as simple to build and maintain, even for newcomers in the Linux world. And, if you install System Workbench for Linux in System Workbench for STM32 you can seamlessly develop and debug asymmetric applications running partly on Linux, partly on the Cortex-M4.
You can get more information from the ac6-tools website and download (registration required) various documents highlighting:

STM32F072RBT6 not properly modeled in OPENOCD? 64K instead of 128K

Hi


Check the linker script on your project. The memory definitions are in this script file:

/* Memories definition */
MEMORY
{
RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 16K
ROM (rx) : ORIGIN = 0x8000000, LENGTH = 128K
}

I don’t know if this has a connection with the OpenOCD.


Regarding the OpenOCD script, do you use this script: “nucleo_f072rb.cfg” ?

Above file include “stm32f0x.cfg”. In this last file seems that the flash size is checked.
But I don’t know further detailes. I have seen that there is a stm32f1x !. Possibly this is not correct.

flash size will be probed
set _FLASHNAME $_CHIPNAME.flash
flash bank $_FLASHNAME stm32f1x 0x08000000 0 0 0 $_TARGETNAME
