I have a project in which I've started from the proximity app example code and added some UART stuff using app_uart.c. The linker is giving me this error immediately after building app_uart.c:
ld: region RAM overflowed with stack
Can this be true? The RAM is 8kB, right? Attaching linker scripts and a screenshot that shows everything included in the project.
More detail from my map file:
