🦋 DESCRIPTION 🦋

Okay so the Firmware Image Download command downloads all or a portion of an image for a future update to the controller. Like, that's the whole gig. The Firmware Image Download command downloads a new image — in whole or in part — to the controller. Both of those things. Yes, literally both. 👑

The way this image can be built? It may be constructed of multiple pieces that get individually downloaded with separate Firmware Image Download commands. So you're not locked into one giant blob, you can piece it together like a lil puzzle 🧩

Each Firmware Image Download command includes a Dword Offset and Number of Dwords that specify a dword range. Those two are the ones telling the controller exactly which slice of the image you're handing over. 🙈

⚠️ Genuinely important, bestie: the new firmware image is not activated as part of the Firmware Image Download command. Downloading ≠ activating, those are two separate moments, do not confuse them 💀 Use the nvme_mi_admin_fw_commit to activate a newly downloaded image. That's the glow-up step. Periodt. ✨

🌈 RETURN 🌈

0 on success, non-zero on failure. Iconic either way, but you want the 0. 🍓
