timer is not woring

[ps_anu]

hi........

i am using nrf52382 , merged the uart , timer and twi .while debugging i am getting the error unknown function 0x000008C8

Hi,

It sounds like you have ended up in the error/hardfault handler. Did you follow this debug method, to see if any functions are returning error codes?

Which instance number are you using for the TIMER? Note that the softdevice use (and block access to) TIMER0. Can you post your sdk_config.h file?

Best regards,
Jørgen

Have a look at this video tutorial. I need your entire sdk_config.h file, what you posted only show that you have enabled the timer driver.

i couldn't able to post my code , finding some issues

i am getting error in uart event handler

 

[Jørgen Holmefjord]

Most likely you get an error on the UART peripheral, which is passed on to error handler. The errors reported from UART driver, usually corresponds to the errors in ERRORSRC. From your image it looks like the error code is 4, or a FRAMING error. Did you run this on a custom board, or a nRF52 DK? Try running the code one more step, to see what is assigned to error_info struct. Then check the code on the given line number to see if you can catch the error when it is coming in.

i am using custom board nrf52832  ,  i ran the program step by step , it getting error while it entering the

uart_app. see the pic you can clear get
