Hi everyone,
I am using nrf52832 with SDK version 11.0 for an IoT application. I am communicating with Atmel ATWINC 1500 module through SPI in order to connect to Wifi. My code was working fine until I added few new lines of code unrelated to SPI. Now when I run the project on Nordic hardware I get following SPI read errors.
(APP)(ERR)[spi_data_read][385][nmi spi]: Failed data response read...(00) (APP)(ERR)[spi_read_reg][625][nmi spi]: Failed data read...
I know that this error occurs when there is some issue with pin assignment for SPI interface but I have verified all the pin assignments. The stranger thing is that the project starts working fine if I comment out any part of the project totally unrelated with SPI. Following are the results when I compile the project using Eclipse.
'C:/Program Files (x86)/GNU Tools ARM Embedded/5.4 2016q3/bin/arm-none-eabi-size' _build/nrf52832_xxaa.out text data bss dec hex filename 56312 1436 37904 95652 175a4 _build/nrf52832_xxaa.out
It might be a memory issue or some other issue. I have tried debugging it but failed so any leads or suggestion about where the problem might be or how to debug such an issue will be highly appreciated. My Make file and start up file is attached.
