From 1df9cbd70f56bdbb3b8b004d51c8eea7379a28b2 Mon Sep 17 00:00:00 2001 From: Heinrich Schuchardt Date: Mon, 27 Jan 2025 07:49:36 +0100 Subject: [PATCH] examples/api: improve determination of LOAD_ADDR The current load address for the 'demo' binary does not work for qemu_arm_defconfig. The suitability of an address to load an ELF binary and run it does not only depend on the architecture but also on the memory layout of the board. On most boards we can assume that 8 MiB of memory is available above $loadaddr. So $loadaddr + 0x400000 should work there.
