nand_read_data_op(9)

🦋 nand_read_data_op(9) 🦋

okay bestie, this is the Kernel API Manual entry for nand_read_data_op, and she is lowkey iconic. no cap, I’m giving you every detail, every ref, every return value — the whole vibe. 💖

🌸 NAME 🌸

nand_read_data_op — Read data from the NAND

✨ SYNOPSIS ✨

int nand_read_data_op (struct nand_chip *chip , void *buf , unsigned int
       len , bool force_8bit , bool check_only );

🎀 ARGUMENTS 🎀

• chip — The NAND chip
• buf — buffer used to store the data
• len — length of the buffer
• force_8bit — force 8-bit bus access
• check_only — do not actually run the command, only checks if the controller driver supports it

💅 DESCRIPTION 💅

This function does a raw data read on the bus. Usually used after launching another NAND operation like nand_read_page_op. 🫶

⚠️ heads up bestie: this function does not select/unselect the CS line.

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