nand_write_data_op(9)

💖 nand_write_data_op — a Kernel API Manual moment 💖

ok so bestie, we're in the Kernel API Manual today and the main character is nand_write_data_op. she writes data. to the NAND. that's the whole vibe. let's get into it 🫶

---

✨ NAME ✨

nand_write_data_op — Write data from the NAND

📜 SYNOPSIS 📜

int nand_write_data_op (struct nand_chip *chip , const void *buf ,
       unsigned int len , bool force_8bit );

🧚 ARGUMENTS 🧚

• chip — the NAND chip in question, the one and only 👑
• buf — the buffer holding the data you're sending out on the bus, like her little care package 💌
• len — length of the buffer, aka how much of it is actually real
• force_8bit — force 8-bit bus access. yes ma'am, we're doing 8-bit, no negotiating 💅

🌸 DESCRIPTION 🌸

okay so listen. this function does a raw data write on the bus. no fancy stuff, no extra steps, just the raw write, periodt.

usually you're calling her after launching another NAND operation — like nand_write_page_begin_op — like she's the second half of a collab 🤝

and here's the thing bestie, important one: this function does not select/unselect the CS line. not her job, not her problem, not her era. 🙈

Returns 0 on success, a negative error code otherwise. so like, 0 is the slay, negative is the "we need to talk" 💀

and that's the page!! 💅✨

so like, this one's filed under ./drivers/mtd/nand/raw and it's stamped October 2026 — write that down bestie, it's giving future icon energy 🎀💖 go forth and write your data, mwah 🫶🌸
