【求助】N32926启动提示GNAND init failed
从 https://github.com/OpenNuvoton/N32926_Linux_BSP 拉下来的最新代码。使用的Nand型号为：MX30LF1G18AC
然后按照下面步骤编译下载到板子上：
1. tar zxvf rootfs-2.6.35.tar.gz
2. make w55fa92_defconfig
3. ./build nand
4. AutoWriter烧录到nand
重新断电启动后，打印如下：

看了下 drivers/scsi/nuvoton_nand/w55fa92_NandDrv.c 应该已经对这个nand做过支持的，驱动里面有这个nand的ID
有遇到过类似问题的朋友吗？帮忙指点下。谢谢！~ 看到你在群里的信息了，没有遇到过，纯属帮顶。 可以换其他flash试试 楼主的问题搞定了么？同样遇到。 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: 0x800000NVT_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， 0x900000，插上U盘就有两个盘了，直接copy到NAND1-1，
