Debugging fail with "Unknow function at 0x00000A60"

[shubham gupta]

Hiii... Team,

I am developing a project based on the nRF52833 with the nRF5 SDK 17.0.2 and Soft Device S140

code is successfully built.. when i try to debug it showing problem

it shows ("Unknow function at 0x00000A60")

Actually i m using the nrf52832 kit as a "debugger" and my external module is nrf52833.

in simple way i m flashing the code in nrf52833 with help of nrf52832 development kit.

i m uploading the screenshot and my project folder as well.

please help to solve it.

plese open the zip file as given path

C:\nRF5_SDK_17.0.2_d674dde\examples\ble_peripheral\ble_app_uart\pca10056\s140\ses

thanks in advance.0020.ble_app_uart.zip

Hi,

You need to select the PCA101000 (nRF52833 DK) configuration when building for the nRF5833. PCA10056 is for the nRF52840 DK, so that is why you are getting a fault exception on startup.

Best regards,

Vidar

Hi,

You had not enabled the TWI and you had not included your own source files:

[shubham gupta]

Hi,

thanku so much :)

[shubham gupta]

Hi, Vidar.

Howz You?

I want to ask 1 thing..

Actually the code you given to me which is "ble_app_uart_283383.zip"

This code is compiled as i told you before..

but when i dump that code in my external module it is not showing output.

hope You can help.

Thanks..

[Vidar Berg]

Which module is it? Also, do you see if the program gets stuck somewhere when you debug the application? Please post screenshots to show what you  are seeing.

[shubham gupta]

Actually it is My Project Module.. Nrf52833 with AFE4404 (Heartrate and oximeter sensor) and BMA400 (Acclerometer)

this window is showing while debugging..

and on tera term no output.

Thanks.

[Vidar Berg]

You have to press the "play" button to make the application run. The screenshot shows the program is paused at the start of main().
