Compilation Errors

[Murthy Udupa]

BACKGROUND

We have a new custom board in production and have noticed.

1. We cannot do a DFU. We always have to flash by wiring it

2. Sometime the board crashes and needs restart.

We were told by the Manufacturer to use PCA10100 and S113 as the Processor was nRF52833

On further investigation we realised that the processor is not nRF52833 but its a nRF52840 /resized-image/__size/640x480/__key/communityserver-discussions-components-files/4/IMG_5F00_20230722_5F00_085625.jpg

When we tried to recompile with PCA10100 and S140 (as processor is nRF840)  we got the following errors.

ugmurthy$ nrfjprog --recover --log
ERROR: No debuggers were discovered.

Can the reader provide some clues as to how we may proceed to compile our code

Hello,

It would be better if you could start with a 'PCA10056' (Supported boards) project which is configured for the 52840 DK board. Just changing the pre-processor definition from 52833 to 52840 is not sufficient, you would also need to change the linker settings, startup files, debugger settings to match the device type. 

The nrjprog error indicates a connectivity problem between your PC and debugger. It should not be related to the FW or board you are trying to program. Have you tried to see if it works on another PC or USB cable?

Best regards,

Vidar

Thanks Vidar Berg,

I will try with 'PCA10056' first. 

I had not connected any board to USB and the nrfprog could be related to that. My first goal was to see it the code compiles.

Hi Vidar,

Made necessary changes to sdk_config.h and can now compile without errors.

However, I get 100+ linkers errors : I know I am missing some linker settings (you had mentioned this will need change) but cannot resolve. Grateful for any leads on this one.

Thanks in advance

Hi,

The linker errors suggest that you are either missing source files in your project or they haven't been enabled in sdk_config.h. For example, does your project include the nrfx_saadc.c file?

Thanks very much. That is good enough clue for me to pursue this.

Hi Vidar,

All compilation issues solved. Yes, the issues was many files were not included.
