My application stopped running properly after I edited the nrf_drv_twi.c file

[Robert Haddad]

Hi,

So I was having an error which caused my application to stall in the "do_stop_check" part of the nrf_drv_twi.c file, so I added a bit of code to check if I could figure out the issue. This code caused the stall to happen immediatley instead of it happening after a good amount of time (which was new). So I removed the code I put and now my application is stalling before it even starts the main loop. When I put back the code it goes back to stalling at nrf_drv_twi.c immediately but I can't get it back to what it was before. Please someone help.

Here is the code I added:

// In the top
uint8_t do_stop_check_count = 0;

// At the end of the static bool twi_transfer function before the last statement (return true;)
		if(do_stop_check_count >= 5){
			do_stop_check_count = 0;
			return false;
		} else {
			do_stop_check_count++;
		}

Thank you in advance,

Robert

Hi,

Which SDK version are you using? nrf_drv_twi.c has not contained the function twi_transfer() since SDK 14.2.0. Have you tried migrating your application to a more recent SDK version?

Best regards,
Jørgen

Hi Jørgen,

Yes I'm using SDK version 12.3. That's what I started with and I'm scared to migrate to something else because I'm still getting the hang of the system.

Best regards,

Robert
