M25P(4)
πΎ M25P(4) β like, the kernel interfaces manual, bestie πΎ
okay so this is the m25p page from the Kernel Interfaces Manual and honestly? it's short, it's sweet, and it's giving "niche driver that absolutely slays at one specific job." let's get into it π
β¨ NAME β¨
m25p β the STMicroelectronics M25P family of SPI-connected flash devices π
like, that's the whole vibe. a family of flash chips, all SPI-connected, all M25P. iconic behavior, no notes. π
β¨ SYNOPSIS β¨
m25p* at spi0 slave 0
that's it. that's the configuration. she attaches at spi0 on slave 0 and minds her own business. simple, clean, main character energy. πΈ
π¦ DESCRIPTION π¦
k so the m25p driver is the one that provides support for STMicrolelectronics' M25P family of SPI connected NOR flash devices. that's literally the whole thing. it's a driver, it supports the family, the family is NOR flash, the flash is SPI connected. periodt. π
π«Ά SEE ALSO π«Ά
spi(4)β go read about the SPI bus if you want the full lore, iykyk π§
β HISTORY β
fun fact time, gather round besties: the machine-independent m25p driver was written by Garrett D'Amore for the Champaign-Urbana Community Wireless Network Project (CUWiN), and it appeared in NetBSD 4.0. so like, this driver has roots. it has a whole origin story. we love a humble beginning. π
π BUGS π
okay so this is the part where we get real. some important bits that are vital for use as a mass storage device are still missing. and by "some important bits" we mean:
- there is no API to erase the device π
- there is no support for device partitioning π
so like, yes she's a flash driver, but no, you cannot just treat her like a disk yet. mass storage? not today, bestie. she's not there. do not attempt. π
so there u have it: tiny page, huge personality, one(1) syscall-shaped hole where erasing should be. stay hydrated, read ur man pages, and remember β m25p* at spi0 slave 0. π
β this cutie came to you from Debian, dated October 9, 2006, and it's filed under M25P(4) β¨ mwah, love u, bye π
