I am using Keil software to run the example code of 52832 or 52840 (preferably 52832) on the 52833 chip. How should I modify this?

Now I am using the example code of sdk17.1.0 s32. After opening it with Keil, I found that it is the example code of 52832. I changed the device to nRF52833_xxAA, but after recompiling, there are still the following issues and it cannot run properly on 52833. What else do I need to do?

Rebuild started: Project: ble_app_multilink_central_pca10040_s132
*** Using Compiler 'V5.06 update 6 (build 750)', folder: 'C:\Keil_v5\ARM\ARMCC\Bin'
Rebuild target 'nrf52832_xxaa'
Note: source file 'RTE\Device\nRF52833_xxAA\system_nrf52.c' - object file renamed from '.\_build\system_nrf52.o' to '.\_build\system_nrf52_1.o'.

Hi,

With Keil it is easier to change the files in the GUI. But you need to do essentially the same things (change chip variant, change defines, remove startup files etc related to the old chip and add files related to the new chip, and adjust memory start addresses and sizes). It is a good idea to compare with an exmaple project for nRF52833 (there are some of those in the SDK), as it is easy to miss somethings.

Regardign the error, it looks to me like you hav emade a lot of changes but not cleaned the build folder? When you do big changes, you need to clean all before doing a re-build. If it still fails (and after you have updated everythign as outlined), can you share the full log? (You can also change the project so that I can have a look on my end.)

hi I will configure according to what you said：“FLASH_PH_START=0x0;FLASH_PH_SIZE=0x40000;RAM_PH_START=0x20000000;RAM_PH_SIZE=0x8000;FLASH_START=0x27000;FLASH_SIZE=0x19000;RAM_START=0x20002ae8;RAM_SIZE=0x5518”；But now there are some errors：

".reserved_ram is too large to fit in RAM1 memory segment

.data_run is too large to fit in RAM1 memory segment

.bss is too large to fit in RAM1 memory segment

section .heap overlaps absolute placed section .stack

section .reserved_ram VMA wraps around address space

section .stack VMA [20002000,20003fff] overlaps section .reserved_ram VMA [20000000,00004397]"

As above,The error in the last line seems to be due to overlapping addresses. How should I modify this?

just to add :

I am currently porting the example code of 52832 to 52833 in Keil; On Egger Embedded Studio, the sample code of 52840 is ported to 52833. May I ask which one is better to operate?
