nrf52 RTT LOG

PiKa PiKa

Hi

how can i display application logs after merging application and secure_bootloader

the secure_bootloader souce I used is \examples\dfu\secure_bootloader\pca10040_uart_debug\ses

but after merging application and secure_bootloader I can only see the bootloader logs,

how can i display application logs?

    Hi,

    The problem is that the bootloader and application are completely independent, and the RTT viewer will search for an RTT block in memory and select the first (whichever it is). A simple way to work around this is to only use RTT logging in either the bootloader or application at the same time, but for a proper solution the best is probably to ensure they use the same memory block for RTT. A customer described how you can do that in this thread (exact method depends on which toolchain you are using, but the principles remain the same).
