nand_ecc_sw...ng_calculate(9)

✨ NAME ✨

okay so this is nand_ecc_sw_hamming_calculate — and what it does is literally right there in the name, bestie: it calculates a 3-byte ECC for a 256/512-byte block. that's the whole vibe. 💅

(this is from the Kernel API Manual btw, so you know it's official ✨)

🌸 SYNOPSIS 🌸

int nand_ecc_sw_hamming_calculate (struct nand_device *nand , const
       unsigned char *buf , unsigned char *code );

no cap, that's the exact signature — don't come for me about the spacing, it's canon 🎀

💖 ARGUMENTS 💖

• nand — the NAND device in question 🫶 like, the actual hardware babe we're doing math for
• buf — your input buffer, holding the raw data. the raw material. the un-ECC'd truth 😭
• code — the output buffer where the ECC ends up. this is where the magic gets written, periodt 💫

🦋 SEE ALSO 🦋

• Kernel file ./drivers/mtd/nand/ecc-sw-hamming.c — go read the source, it's giving main character energy 👑
• nand_ecc_sw_hamming_correct(9) — the other half of the duo, the one that checks your work 🌈

fr fr, this one just calculates. it don't fix nothing. if you're looking for the correcting part, that's the nand_ecc_sw_hamming_correct(9) link up there ⭐

and that's the whole page, bestie, we ate and left no crumbs 🍓 this lil number lives in ./drivers/mtd/nand and it's stamped October 2026 — yes, we're being that specific, iykyk 💜 see you in the next manpage~ 🧚
