What modifications are needed to run the example code for Nordic 52832 on 52833?

as show:What modifications are needed to run the example code ble_multilink_central for Nordic 52832 on 52833? Please provide a detailed explanation

[curt_z]

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?

[curt_z]

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'.

[curt_z]

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?

Hi,

I would not expect to see these errors. But there are some strange values here, like 32 kB RAM size, which I see is my mistake as I picked a 100100e project to copy values from and not a 100100 project.

The line should be like this (but still with project specific adjustments as needed:

      linker_section_placement_macros="FLASH_PH_START=0x0;FLASH_PH_SIZE=0x80000;RAM_PH_START=0x20000000;RAM_PH_SIZE=0x20000;FLASH_START=0x0;FLASH_SIZE=0x80000;RAM_START=0x20000000;RAM_SIZE=0x20000"

*_PH_* sizes si the total physical size. And the other start address and sizes is the remaning memory (flash and RAM) left to the application, excluding what is used by the SoftDevice.

If you still don't get it working, can you share the project files (all fiels within the project folder) so that I can take a look?

I would personally prefer Segger Embedded Studio as that is the IDE that we promote with resent versions of the nRF5 SDK. It is also free for use with Nordic devices, unlike Keil. It also has some additional benefits like being cross platform and a slightly more modern feel. But Keil is also a supported IDE, so you can use whichever you prefer.

hi Due to some reasons, I am unable to try it on the board at the moment. I can only paste the areas that I believe need to be modified to port the example code from 52840 to 52833 chip, as follows：

Could you please check if there are any further areas that need to be modified? I will try again on the board later and then post the results.

[curt_z]

According to your modifications, it is still incorrect (52840 to 52833 in Segger Embedded Studio)

[Einar Thorsrud]

Hi,

I don't see any obvious mistakes here. Can you show in what way this fails? And show errors?

Also, can you upload the project files here? (you can zip and drag and drop or use Insert -> Image/video/file). That way I can get a better overview, and if you incldue the full project I can test on my end. (If you do not want to share it in public you can make a private ticket and refer to this one).

[curt_z]

hi

I am currently using the sample code in 17.1.0sdk, and have not made any changes. You can download it on the official nordic website. The code I am debugging is in the F:  nrf_sdk  DeviceDownload  nRF5_SDK_17.1.0_ddde560  nRF5_SDK_17.1.0_ddde560  examples  ble_central  ble_app_multilink_central  pca10056  s140  ses directory

[curt_z]

just to add : In my opinion, “F:\nrf_sdk\DeviceDownload\nRF5_SDK_17.1.0_ddde560\nRF5_SDK_17.1.0_ddde560\examples\ble_central\ble_app_multilink_central\pca10056\s140\ses”this code is running on board 52840. I would like to run this code on board 52833. Please paste the modified differences

[Einar Thorsrud]

Hi,

I see I forgot one thing. The linker_section_placements_segments also needs to be adjusted. I have uploaded a new project file for ble_app_multilink_central for the nRF52833 DK here, which has all the changes you need: 6837.pca10100.zip
