Hi,
I am doing the project in nRF2832 , where I need to collect some data from the sensor and temperature value that i need to save in the .CSV file format in SD cARD. and I need to Transfer the particular File to the Central device (Mobile phone or another nRF52 device) using BLE .
I have gone through the FATFS example there i found the interfacing the SD card and creating the file and writing the text in it . and build and run successfully.
When I am try to read the file i have occur an issue called
Building ‘fatfs_pca10040’ from solution ‘fatfs_pca10040’ in configuration ‘Release’
Compiling ‘main.c’
Linking fatfs_pca10040.elf
.bss is too large to fit in RAM memory segment
.heap is too large to fit in RAM memory segment
section .heap overlaps absolute placed section .stack
Build failed
I gone thorugh the link and attached file also here
Main.c file is
