nand flash shortage

memory is only 2 GB. What should I do?I have come up with a solution, that is, to split the volume, not to compress the volume, but to download files one by one and verify MD5 (if the image is downloaded incorrectly, it will be re-downloaded, obviously not good ), then put the NAND.I think it is much better to use livesuit (phonenixsuit). If you can try it.I want to figure out the busybox image first.Original tllHttp://forum.cubietech.com/forum.php? MoD = viewthread tid = 2007 extra = Page %

Requirement: The uboot and system have been transplanted, and the next step is to build the upgrade tool for later debugging convenience, and to learn by yourself Expectation: Understand the memory ing, understand the MTD device operation framework, and understand the TFTP source code. Plan: three steps: Step 1: port the TFTP source code: see the TFTP source code in busybox and put it in nandup as part of the upgrade tool. You can download the image file to the/tmp directory by executing./na

checkcode cp0 ~ Cp5, remaining 2 position 1: When writing data to NAND Flash, we generate a verification code and save it to the spare data area in flash. When reading data from flash, a new ECC verification code is generated, which is different from the old one read by the spare data area: Result 0: The data is co

between NANDFlash and DRAM will rapidly increase as system products move towards "affordable fashion"Although DRAM and NANDFlash complement each other in terms of functions, the trend of low-price fashion (high value/low price) is becoming more and more popular in systems such as Ultrabook and smart phones, DRAMeXchange expects that the future competition between DRAM and NANDFlash will gradually increase. We believe that the relevant OEM/ODM companies will use resources for NANDFlash
