芯片:STM32L496RGT,使用fal组件和easyflash。flash驱动用的是rtt的drv_flash_l4.c fal层分区是(0-1000KB)APP、(1000-1024KB)PARAMS。fal层初始化成功,因为曾经移植过littlefs,这部分比较熟悉。
easyflash格式化head不知道是不是成功了,如下: Read data success. Start from 0x00000000, size is 200. The data is: Offset (h) 00 01 02 03 04 05 06 07 08 09 0A 0B 0C 0D 0E 0F [00000000] 00 FF FF FF FF FF FF FF FF FF FF FF FF FF FF FF ................

easyflash的menuconfig配置大致如下: use ENV Erase MIN:2048;Write MIN:64bits;Start addr:0 Version:V4.1.0
问题是:初始化默认环境变量时,会从offset=8开始写入flash,而这里已经被head写过了,因此HAL_FLASH_Program函数失败了。
大致看了下代码,了解到写环境变量时将申请flash块地址,而这个申请是easyflash管理的,在不清楚原理的情况下不敢贸然改动。
想请教的是,easyflash移植到L4系列中是否有问题的地方?

详细读了项目readme,发现4.0以上版本不支持L4系列片内flash。切换到V3.3.0成功移植。
Sorry, something went wrong.
L4 的片上 Flash 不支持逆序写入,所以请使用 V3 版本,V4 版本是没法使用的哈
