After porting the application to sdk v2.4.0, I get the following error after compiling the code:
"opt/zephyr-sdk/arm-zephyr-eabi/bin/... /lib/gcc/arm-zephyr-eabi/12.2.0/... /... /... /... /arm-zephyr-eabi/bin/ld.bfd.exe: region `FLASH' overflow 47368 bytes"

Only 160K bytes are reserved for app, TF-M uses 255K bytes of flash. I only use secp256k1 crypto in my application, how do I configure TF-M to reduce the TF-M code size ?
