spear_mtd_read(9)

✨ NAME ✨

Okay so this is the spear_mtd_read(9) page from the Kernel API Manual, bestie, and it's giving "flash read operation requested by the user" energy. No cap. 💅

spear_mtd_read — performs flash read operation as requested by the user.

🌸 SYNOPSIS 🌸

int spear_mtd_read (struct mtd_info *mtd , loff_t from , size_t len ,
       size_t *retlen , u8 *buf );

🎀 ARGUMENTS 🎀

• mtd — MTD information of the memory bank. Like the flash chip's official little info card. 💳
• from — Address from which to start read. Where the reading begins, periodt.
• len — Number of bytes to be read. How much we're grabbing.
• retlen — Fills the Number of bytes actually read. So you know what actually happened.
• buf — Fills this after reading. Yes, that's literally what it says. 🙈

🦋 DESCRIPTION 🦋

Read an address range from the flash chip. The address range may be any size provided it is within the physical boundaries. Returns 0 on success, non zero otherwise. ✨
