WitrynaThe above procedure assumes that U-Boot and the Linux kernel are configured to access the NAND flash using the same parameters and ECC method. I used nand scrub to remove the bad block introduced by the successfull UBI image installation by the ubiformat tool. It's a good point that the write.trimffs should be used. Witryna27 lip 2024 · The multilevel per cell technology and continued scaling down process technology significantly improves the storage density of NAND flash memory but also brings about a challenge in that data reliability degrades due to the serious noise. To ensure the data reliability, many noise mitigation technologies have been proposed. …
