Arduino for STM32

Finally i managed to make it work somehow and it does the job nicely. Currently i have no time to post the full code here but if anyone is interested just let me know.

Is there an example on how to implement I2S with HAL for the official core? I'm using STM32F4 Discovery board and would like to setup full-duplex communication with an external CODEC (Analog Devices adau1701). The stm32 should be the master and generate the master clock as well serial clock and word...

There are 2 SRAM: SRAM1 and SRAM2. They are contiguous so normally, you should have 112k(SRAM1) + 16k(SRAM2). Setting the estack at 0x2001 C000 is to use only SRAM1. Maybe a config issue on your board. Ok thank you, I've noticed that, so I should set it to 0x2001FFFF (or 0x20020000 ?) to include SR...

An easy way to do that is to modify only the boards.txt file by adding the following 2 lines: # DISCO_F407VG board Disco.menu.pnum.DISCO_F407VG=STM32F407G-DISC1 Disco.menu.pnum.DISCO_F407VG.node=DIS_F407VG Disco.menu.pnum.DISCO_F407VG.upload.maximum_size=1048576 Disco.menu.pnum.DISCO_F407VG.upload....

Don't know, don't have the right knowledge to link (no pun intended) the missing dots :D However if I replace this line : _estack = ORIGIN(RAM) + LENGTH(RAM) ; with this: _estack = 0x2001c000; the application (simple blink) starts from address I set. All the rest is almost the same. The memory decla...

ok, somehow after trying sooo many times i made it work by coyping the stm32_flash.ld file (attached) to ldscript.ld

Is there a better way of doing it without replacing core files? I'm sure there is but i can't figure it out.

ok thank you, now it doesn't spit errors at compile anymore. However i still can't make the application start from different address. I have the build_opt.h file with vector offset declared and the linkerscript modified as this: MEMORY { CCMRAM (xrw) : ORIGIN = 0x10000000, LENGTH = 64K RAM (xrw) : O...

I've been trying to do the same thing with CubeIDE as explained in ST application note and it works fine. From CubeIDE project i only need to change the following files: system_stm32f4xx.c #define VECT_TAB_OFFSET 0x8000 /*!< Vector Table base offset field. This value must be a multiple of 0x200. */ ...

Ok, i googled a bit and i guess the linker script is stm32_flash.ld where i can find the following: MEMORY { FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 1024K RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 112K MEMORY_B1 (rx) : ORIGIN = 0x60000000, LENGTH = 0K } This is from the upgrade application firmwa...

Thank you for fast reply.

Unfortunately i don't know what linkerscript is and where i can find it. Can you help?
