t3_load_fw(9)

🌸 NAME 🌸

t3_load_fw — download firmware 💾✨

Okay so real talk, this is page t3_load_fw(9) from the Kernel API Manual, and its entire personality is "download firmware." That's it. That's the job. And honestly? Iconic of it to not overexplain 🎀

---

✨ SYNOPSIS ✨

int t3_load_fw (struct adapter *adapter , const u8 *fw_data , unsigned int size );

Three args, no drama, no cap 💅

---

🎀 ARGUMENTS 🎀

• adapter — the adapter. The whole card, the main character, the one we're doing all this for 👑
• fw_data — the firmware image to write. It's giving "the payload," "the actual goods" 🦋
• size — image size. So we know how much of the good stuff we're dealing with 📏

---

🔥 DESCRIPTION 🔥

So here's the vibe: you take the firmware image you were handed and you write it to the card's serial flash. That's the whole task, no plot twists 💫

But before you go shoving bytes around, bestie, know that this FW image has sections, and they're in a very specific order:

1. size - 8 bytes of code and data 👀
2. followed by 4 bytes of FW version 🔢
3. followed by the 32-bit 1's complement checksum of the whole image ✅

The checksum covers the whole image — every last byte of it. It's literally guarding the entire thing, like that one friend who keeps the group chat receipts 😭
