AllWinner全志V3s荔枝派zero板子用MX25L256 spi nor flash, sunxi-fel烧完之后发现启动不了:

有没有大神遇到过这个问题？

赶脚， 应该没毛病.
能检测出制造商和器件Id, 容量也检出 32MiB

修改 sun8i.h,
把spi 速度降到12M, 重新编译,
再烧一次flash,
看看有没有效果.

然鹅，还是没卵用:

换了一片 MX25L256 还是一毛一样的问题！
看来可能是板子有问题。

刚刚拿了两片板子交换Falsh,
正常的板子用W25Q256, 不正常的板子用MX25L256,
发现正常的板子变不正常，
不正常板子变正常了，
说明问题出在MX25L256 这个 FLASH上。
下午继续查查

根据这行你查下代码看看是什么问题？
在u-boot源码目录根据 w25q256字符串搜到 ./drivers/mtd/spi/spi_flash_ids.c
找到 c2 20 19 那行: {"mx25l25635f", INFO(0xc22019, 0x0, 64 * 1024, 512, RD_FULL | WR_QPP) },
发现前面有个宏: #ifdef CONFIG_SPI_FLASH_MACRONIX
突然灵光一闪，去 .config 把这个宏打开，重新编译烧录运行，果然可以了。
感谢大神.
