Detailed Description

The producer/consumer dual-core pattern: the Cortex-M85 releases the Cortex-M33 and then does nothing but wait while the M33 runs a counting loop entirely on its own, publishing progress into a shared-SRAM struct. The M85 confirms the M33 booted from a signature field, yields on a bounded poll, and reads the final count back – a value only the second core actually executing can produce. dualcore_mailbox is the other shape, where the M85 drives every request/reply round.

The shared struct is pinned at 0x22100000, the start of the upper on-chip SRAM region and below the M33's own bank at 0x22190000; both linker scripts leave that address unclaimed, so the same physical bytes back the struct on both sides. The M33 image is built separately, objcopy'd into a .cpu1_image blob and linked into the M85 ELF, so one flash drops both cores' code into MRAM.
