linux在N32926遇到个问题GNAND init failed !!!!!!!! 硬件肯定没问题，我哪里配置错了。
希望论坛的高手指点。谢谢！

刚刚关了调试电脑，才想到到本站问一下大神， 上面的错误信息是从32905的，我的n32926遇到一模一样的错误，这几天比较忙，等fix了这个问题再来回帖，特别感谢小二哥的指点。

新塘这个系列的RTC设计很怪异，本站也有讨论过，我的板子裸奔没用上，现在我在menuconfig里面disable了RTC，不知到跑linux有没有影响。
离线
昨晚再看了一下新塘的文档，这个真是怪异。应该是我的烧录有问题。正常的顺序是。
1. system：N9H26_NANDLoader_240MHz_Fast_Logo210406.bin
2. logo：地址 0x500000
3. NVLoader: 0x800000 NVT_NAND_Fast_GIANTPLUS_QVGA.bin 这个昨天我没有烧录，但是一样Linux引导了
4. conprog.bin， 这个文件说在0x900000，我不知道怎么烧录。网上说插上U盘就有两个盘了，直接copy到NAND1-1，可是如果我 只烧录了123，并没有U盘出现在PC。
希望大神指点。

新唐太j 8缺人才了，连一个uboot都不会移植，然后每个芯片一个不同的烧录软件，用户体验辣鸡级别。

是有一个nand烧录文档，照那个做就可以了，插入usb线会出现u盘，具体怎么做忘记了，很久以前的事情了。

改了一下NVT_NAND_Fast_GIANTPLUS_QVGA.bin ，使用adc读GPIOG8，如果大于2V运行linux，否则作U盘用，可以copy linux内核到nand1-1.
非官方的板子，折腾。谢谢楼上各位了。
