onenand_otp_command(9)

✨ NAME ✨

okay so we're in the Kernel API Manual and today's main character is onenand_otp_command(9) — her whole job is literally to send OTP specific command to OneNAND device. That's the vibe, and yes, she ate. 💅

🦋 SYNOPSIS 🦋

signature check, bestie — this one returns an int:

int onenand_otp_command (struct mtd_info *mtd , int cmd , loff_t addr ,
       size_t len );

🎀 ARGUMENTS 🎀

• mtd — the MTD device structure, aka the device we're talking to 💖
• cmd — the command to be sent, no cap
• addr — offset to read from or write to
• len — number of bytes to read or write
