STM32H563ZI LINKER

[Recep]

Hi,

I am working on freertos plus tcp library with STM32H563ZI, but how must I make memory otions in linker file?

like: 

RAM (xrw) : ORIGIN = 0x20000000, LENGTH = 320K
FLASH (rx) : ORIGIN = 0x08000000, LENGTH = 2048K
RAM1 (xrw) : ORIGIN = 0x20000000, LENGTH = 256K
RAM2 (xrw) : ORIGIN = 0x20040000, LENGTH = 64K
RAM3 (xrw) : ORIGIN = 0x20050000, LENGTH = 320K

it is wrong I know but how can I make this right ?

thanks

but I made it like this:

and still didn't work

gave me this error:

Hi @Recep , 

You need to modify the SRAM address as showing :
SRAM1 : 0x0A00 0000
SRAM1 : 0x0A04 0000
SRAM1 : 0x0A05 0000

The eth memory in FreeRTOS+ TCP for STM32H7 is defined here.

Documentation: https://github.com/FreeRTOS/FreeRTOS-Plus-TCP/blob/b3289a7788710b6ad1ce5f5ff92dce29f3fd4529/source/portable/NetworkInterface/STM32Hxx/readme.md?plain=1#L38

 

They don't seem to have a separate source for STM32H5 yet.

Hi Recep,

I'm just starting a project with ethernet on the H563ZI and am considering using lwip or FreeRTOS+TCP.

Would you have references for the porting that you did? I see only H7 is included in the official FreeRTOS+TCP project. 

Thanks

hi,

just used  https://github.com/FreeRTOS/FreeRTOS/releases/download/202212.01/FreeRTOSv202212.01.zip

Freertos + TCP  libraries  in this

but  you need to change the hal h7 includes  to  h5 includes   

 

path is like -> FreeRTOS-Plus-TCP/source/portable/Networkinterface/STM32Hxx/Networkinterface.c

all the codes in the Networkinterface.c  almost the same  but includes

[Egolt.1]

Hi @Recep, I tried to follow your suggestion of using the files in FreeRTOS-Plus-TCP\source\portable\NetworkInterface\STM32Hxx for STM32H5 by just renaming the relevant H7 files to H5 but I have this compiler error at stm32hxx_hal_eth.h that seems to refer a define that H5 does not have (In the H7 version it is exist in stm32h743xx.h):

How did you resolve this?

Thanks!
