Hi,
Just curious to know if anyone else had this issue and how they solved it.
My colleagues and I are working on code based on the Nordic Uart Service, in SDK13.1.0 with SD132v4.0.2 on an nRF52832 chip. For better context, colleagues develop using Kiel on Windows, where as I am developing on a Mac (NetBeans + GCC setup, GNU_VERSION = 6.3.1).
Our test project interfaces with sensors via TWI and SPI and sends data over BLE. When programmed through kiel, the device works fine (i.e. can set up interfaces, collect data, connect and send data etc.).
The same project when downloaded into my environment, can compile, build and flash code just fine. Except the following:
- TWI init() works fine.
- on attempting to initialize the first sensor and writing to it over TWI, the twi handler never gets called, and hence hangs. (e.g. nrf_drv_twi_tx() returns NRF_SUCCESS)
Similar behavior is also seen with the SPI.
I know my development environment works fine when I have to program a PCA10040 dev kit, with code from the example projects for testing. I also have a pretty good understanding of setting up the Makefile and adjusting the RAM allocations through the .ld file. sdk_config.h also has the necessary flags enabled for running the interfaces (else they wouldn't work when programmed through Kiel either). I am confused as to why a project would compile and run fine through Kiel, but will not run the same through GCC.
I have also tried flashing the twi_scanner project to a devkit, without the soft device, which works fine too.
I am guessing that I may be missing something else in my development setup, but it just does not seem obvious to me. I would be glad if some one has found the solution to this before!
Thanks, Jai
