STM32F2xx support in Chibios 3.0.3

[ana_lazareva]

Hi!

How to configure ChibiStudio to work with STM32F2?

What I have already done:
1. External Tools Configuration -> arguments for openocd.exe: -c "telnet_port 4444" -s "C:\ChibiStudio\tools\openocd\scripts" -f "interface/stlink-v2.cfg" -f "target/stm32f2x_stlink.cfg"
2. board.h:

/*
* MCU type as defined in the ST header.
*/
#define STM32F2XX

3. mcuconf.h: #define STM32F2xx_MCUCONF


But it does't work still.
Need help!)

Hi,

You need to start from an F407 project, the changes you made are OK however you should better describe the problem.

Also check:
- Maximum frequency, it is 120MHz for the F2, you need to set proper values in mcuconf.h.
- Board files, those are board-specific so you need to create new ones for your board.

Maybe I should change STM32F407xG.ld file, because memory setup is wrong there?

There is
MEMORY
{
flash : org = 0x08000000, len = 1M
ram0 : org = 0x20000000, len = 128k /* SRAM1 + SRAM2 */
ram1 : org = 0x20000000, len = 112k /* SRAM1 */
ram2 : org = 0x2001C000, len = 16k /* SRAM2 */
ram3 : org = 0x00000000, len = 0
ram4 : org = 0x10000000, len = 64k /* CCM SRAM */
ram5 : org = 0x40024000, len = 4k /* BCKP SRAM */
ram6 : org = 0x00000000, len = 0
ram7 : org = 0x00000000, len = 0
}

and I need (I just think so):

MEMORY
{
flash : org = 0x08000000, len = 256k
ram0 : org = 0x20000000, len = 128k
ram1 : org = 0x00000000, len = 0
ram2 : org = 0x00000000, len = 0
ram3 : org = 0x00000000, len = 0
ram4 : org = 0x00000000, len = 0
ram5 : org = 0x00000000, len = 0
ram6 : org = 0x00000000, len = 0
ram7 : org = 0x00000000, len = 0
}


And what about Makefile? Should I specify MCU?

There is: MCU = cortex-m4
I need: MCU = cortex-m3

Maybe I should write board-scecific file here: os/ext/CMSIS/ST?

Hi,

I will post a template application here tomorrow, I will not be able to test it because I don't have any F2 HW but it will compile.

Giovanni

[ana_lazareva]

Ok, thanks!

[Giovanni]

Hi,

I added the demo to the repository as \demos\STM32\RT-STM32F207-DISCOVERY

You need to checkout the latest code from subversion: https://sourceforge.net/p/chibios/svn/HEAD/tree/trunk/

It compiles fine but I have not tested it on HW, it assumes an STM32F407-Discovery board with the MCU replaced by an STM32F207.

Hi!

Thanks for the demo.

What I've done:

1. Added files: sym32f2xx.h, system_stm32f2xx.h and stm32f207xx.h to the \os\ext\CMSIS\ST directory.

2. Created directory \os\common\ports\ARMCMx\devices\STM32F2xx and added there file cmparams.h with right cortex model number.

After that my project builds well.

But now I have the other problem:
My project runs well, but when I try to debug I have this message in the Console tab:
WARNING! The target is already running. All changes GDB did to registers will be discarded! Waiting for target to halt.

Why?
