I am trying to build the sys_heap example with tfm and mcuboot with a very simple custom board based on the nrf9160dk_nrf9160 using NCS v2.2.0. But when I run it on my board, MCUboot is unable to find a bootable image. Some times the examples runs correctly, but most of the times it doesn't. The reason for mcuboot not finding a bootable image is because it is using the flash partitions defined in the device tree, but the memory report shows the correct flash partitions . I have determined this by editing get_flash_area_from_id in flash_map_priv.h (see both code blocks). I am not sure how to fix this issue, I have included my project.
static inline struct flash_area const *get_flash_area_from_id(int idx)
{
for (int i = 0; i < flash_map_entries; i++) {
printk ("flash_map_priv %02u -> (%02u/%02u): %08lx-%08lx (%08x) %s\n", idx, flash_map[i].fa_id, flash_map_entries, flash_map[i].fa_off, flash_map[i].fa_off + flash_map[i].fa_size, flash_map[i].fa_size, flash_map[i].fa_dev->name);
if (flash_map[i].fa_id == idx) {
return &flash_map[i];
}
}
return NULL;
}
