After spending another 30 hoiurs or so experimenting, the following prj.conf settings helped to resolve the issues.

# Heap and stacks
CONFIG_THREAD_NAME=y
CONFIG_HEAP_MEM_POOL_SIZE=16384
CONFIG_MAIN_STACK_SIZE=16384
CONFIG_SYSTEM_WORKQUEUE_STACK_SIZE=4096
CONFIG_HW_STACK_PROTECTION=y

#AWS FOTA MEMORY
CONFIG_DOWNLOAD_CLIENT_HTTP_FRAG_SIZE_1024=y
CONFIG_DOWNLOAD_CLIENT_STACK_SIZE=4096
CONFIG_DOWNLOAD_CLIENT_BUF_SIZE=2048
CONFIG_DOWNLOAD_CLIENT_MAX_HOSTNAME_SIZE=128

#AWS FOTA

Tha application is mainly GPS, AGPS and collecting data from UART.

I've increased stack variables to 32768, it seemed to help a little bit, by that FOTA occasionally ran and completed, but usually failed.

Hello,

The technical support team will be out due to Easter Holiday until Tuesday April 19. We're sorry for the inconvenience.

Looks like you might need to increase the stack size e.g.

CONFIG_MAIN_STACK_SIZE=1280

What does your application do? Where does it give a hard fault?

Kind regards,
Øyvind
