The address and sizes look correct now for the corrected memory.x. For the old memory.x file:

```txt
/* Define sections for placing symbols into the extra memory regions above.   */
/* This makes them accessible from code.                                      */
SECTIONS {
  .sram1 (NOLOAD) : ALIGN(8) {
    *(.sram1 .sram1.*);
    . = ALIGN(4);
    } > SRAM_1
};
```

The . = ALIGN(4); seems to be problematic, and here I also get the unchanged addresses where .data/.bss/ etc are at the old base address even though flip-link is used.
