nand_get_features_op(9)

💅 nand_get_features_op(9) 💅

okay bestie, welcome to the Kernel API Manual page for nand_get_features_op(9) — it’s giving niche kernel lore, and honestly? iconic. no cap. 💖

---

🌸 NAME 🌸

nand_get_features_op — Do a GET FEATURES operation. that’s the whole assignment, fr fr. ✨

---

✨ SYNOPSIS ✨

here’s the exact signature, bestie — do not freestyle the commas:

int nand_get_features_op (struct nand_chip *chip , u8 feature , void
       *data );

the way that struct nand_chip *chip is just sitting there being main character energy? obsessed. 🫶

🧚 ARGUMENTS 🧚

• chip — The NAND chip. hi bestie 👋
• feature — feature id. yes, just the id. 🎀
• data — 4 bytes of data. literally 4. 😭

---

💖 DESCRIPTION 💖

okay so here’s the tea: this function sends a GET FEATURES command and waits for the NAND to be ready before returning. it’s giving patient, it’s giving polite. 🦋

also important: this function does not select/unselect the CS line — not even a little. so don’t @ it for that, iykyk. 💅

Returns 0 on success, a negative error code otherwise. periodt. 🌈
