And there's no specification on how that wear-leveling works (or doesn't work).

- hwh 5y agoThat is not true. See https://github.com/littlefs-project/littlefs/blob/master/DESIGN.md https://github.com/littlefs-project/littlefs/blob/master/DES... Sorry, as a commenter on this pointed out, the comment I was replying to was probably talking about eMMC. For which indeed no wear levelling is specified by the JEDEC standard - it is a standard that defines the communication protocol between a device and a host system. Newer JEDEC standards define the interface to access vendor specific "health reports", the actual method of wear levelling isn't regularly disclosed by vendors.
- phs2501 5y agoI think the GP was commenting on the lack of specification of eMMC wear leveling, not Littlefs.
- stjohnswarts 5y agoSandisk has multiple documents on this. "They" is a pretty big paintbrush.
- kevin_thibedeau 5y agoYou never know if a marginal brand has licensed the Sandisk patents or implemented them correctly.
