大家好：
我正在使用 NRF 连接 SDK，nrf916 硬件。
我同时使用 spi flash 和 mcuboot。这是我的一些配置：
fstab {
compatible = "zephyr,fstab";
lfs2: lfs2 {
compatible = "zephyr,fstab,littlefs";
mount-point = "/spi_flash";
partition = <&lfs2_part>;
read-size = <1>;
prog-size = <1>;
cache-size = <128>;
lookahead-size = <32>;
block-cycles = <100>;
};
};
&mx25l256 {
partitions {
compatible = "fixed-partitions";
#address-cells = <1>;
#size-cells = <1>;
lfs2_part: partition@0 {
label = "spi_flash1";
reg = <0x00000000 0x00010000>;
};
};
};
***
flash0: flash@0 {
compatible = "soc-nv-flash";
label = "NRF_FLASH";
erase-block-size = < 0x1000 >;
write-block-size = < 0x4 >;
reg = < 0x0 0x100000 >;
partitions {
compatible = "fixed-partitions";
#address-cells = < 0x1 >;
#size-cells = < 0x1 >;
boot_partition: partition@0 {
label = "mcuboot";
reg = < 0x0 0x10000 >;
};
static void recreate_file_system(void)
{
const struct flash_area *pfa = NULL;
int rc;
unsigned int id = (uintptr_t)(m_mp->storage_dev);
rc = flash_area_open(id, &pfa);
if (rc < 0) {
LOG_WRN("can't find flash area %lu: %d", id, rc);
return;
}
LOG_ERR("%d '%s'", __LINE__, m_mp->mnt_point);
LOG_DBG("%d '%s' at 0x%x for 0x%x bytes", __LINE__, pfa->fa_dev_name,
(unsigned int)pfa->fa_off, (unsigned int)pfa->fa_size);
/* Optional wipe flash contents */
if (IS_ENABLED(CONFIG_APP_WIPE_STORAGE)) {
rc = flash_area_erase(pfa, 0, pfa->fa_size);
LOG_WRN("%d Erasing flash area ...[0x%x] ?%d", __LINE__, pfa->fa_size,
rc);
}
flash_area_close(pfa);
}
日志是：

挂载点是'/spi_flash'，没错。 但是起始地址和大小是 0x0、0xc000 ， 它们是mcuboot的。
